Today we return to the Fermi Paradox to contemplate the notion of civilizations which neither expand outwards to colonize the galaxy nor go extinct, but exist as long-term, high-tech civilizations just on their own planet or solar system. To discuss the possible motives and reasoning we will look at the many arguments raised for and against space exploration.
This episode ends Year 2, not with predictions for the future, but rather a discussion of concepts of Black Swan Events and Outside Context Problems, highly unpredictable events which massively impact civilization.
In this episode we begin our look at possible Alien Civilizations by considering the impossible ones. Fiction has introduced a lot of misconceptions about aliens we need to clear away before we can seriously consider them and that begins by looking at some of the common ideas and removing any that rely on the concept of advanced civilization being quite stupid.
We continue our look at hypothetical alien civilizations by discussing the various possible circumstances in which we might first contact them or be contacted by them.
A look at advanced means of altering or controlling the planet's climate and geography, drawing on concepts proposed for terraforming other planets.

In this episode we'll be looking at improvements to rocket systems, with the main focus on re-usability. We will also look a bit deeper at rocketry principles, at some other improvements and alternative uses for rockets, such as oceanic launches, and discuss Metallic Hydrogen, a potential game changing fuel.
We examine the concepts of cyborgs, clarify what they are and how they differ from bionics, androids, and similar concepts. We also discuss some of the lesser known options for augmentation and explore the notion of man-machine integration.
While potentially dangerous, nuclear powered spacecraft offer far faster and more efficient spacecraft than traditional chemical rockets. Today we will examine the various means of using atomic power sources to propel spacecraft, both to get off Earth and to travel to other stars.
Science Fiction loves the Many Worlds Interpretation of Quantum Mechanics, but its implication go far beyond basic Alternate Universes and histories. Today we will explore some of the mind-bending consequences of this theory.
We return to the Moon to explore ways to go beyond simple Lunar Bases to a full-fledged productive colony that can help us travel to other worlds and expand our own.

Part 2 of our look at mega-engineering projects civilizations may tackle on their way to achieving Kardashev 2 status. Teaming up again with Fraser Cain & Universe Today, we look at artificial magnetospheres, mining and disassembling comets, asteroids, and even whole planets, and harvesting the Sun itself.
Today we look at using Space Towers, Buoyant Structures, Airships, and Space Fountains as means of launching spaceships, as well as their other applications to create enormous structures that normal materials could never permit.
This episode begins our look at solutions to the Fermi Paradox - the question of why the Universe appears empty of intelligent life besides ourselves - by looking at some of the reasons why life may simply be very uncommon. Before we can contemplate what might be special about Earth, we first need to consider what might be special about our region of space, and even our epoch of time, or our Universe itself.
The Orbital Ring is a type of launch-assist system that goes beyond moving small ships and crews into space and allows cheap movement of bulk cargo up to space, into orbit, and beyond.
We return to the Megastructures series to examine the the concept of a Dyson Sphere, a means of enclosing a star to gather all of it energy. We will look at myths and misconceptions about Dyson Spheres, as well as a number of additional purposes they can be put to, from allowing interstellar travel to generating black holes or running computers large enough to simulate whole Universes.
In the previous episode we saw how civilizations might not simply survive after all the stars in the Universe had died, but might indeed thrive far better during the Black Hole Era of the Universe. Today, we will go beyond even the Dark Era to examine the concepts or Iron Star Civilizations, Boltzmann Brains, Reversible Computing, and even reversing Entropy itself.
We continue our look at possible explanations why life may be very rare in the Universe by examining our planet itself, and looking at which of its characteristic might be important to intelligence developing and how improbable those traits are for a given planet in a given solar system.
Force fields are a staple of science fiction, but usually regarded as only science fiction, not science fact. Today we'll examine the notion and see what options we might have inside known science, as well as what alternatives might achieve similar effects.
It is often suggested that the reason we don't hear from alien civilizations is that they are in hiding. In this episode, we will explore that notion, and examine why a civilization might hide and how they would go about doing it.
Many technologies are greaty anticipated and predicted, and promise to change our lives. Today we will be looking at some that get less fanfare, but hold the promise to change our lives in profound ways.
We begin the new Outward Bound series by discussing the Colonization of Mars, and survey all the colonizing and terraforming options from the early settlement days to the far future and a Green Mars. We will also look at alternatives to terraforming which might make more sense for Mars, like bioforming the people to the environment, rather than terraforming it to our environment.
We conclude our look at possible explanations why life may be very rare in the Universe by looking at the evolutionary pathway to intelligence and the hurdles between life starting on a planet and migrating off of it.
Following on our look at Space Warfare concepts, we look at popular ideas from science and science fiction for war between planets, or inside a fully colonized solar system or Dyson Swarm.
We continue our look at colonizing the solar system by visiting Venus, and exploring both the options for vast floating habitats in the upper atmosphere as well as full terraforming of the planet.
Ringworlds are a type of megastructure that engulf an entire star, first popularized in Larry Niven's classic novel Ringworld. These constructs a million times larger than Earth have captivated minds for nearly half a century but been considered impossible to build under known science. Today, we will attempt to show otherwise.
We continue our look at hypothetical Alien Civilizations by examining concepts such as Zoo Hypothesis - that aliens may be keeping us secluded from the rest of the galaxy - and the motivation for non-interference, such as the Star Trek Prime Directive.
The concept of enhancing and augmenting animal minds & bodies to be able to use and understand human technology, known as Uplifting, has long fascinated us. Today in this two-part collaboration with John Michael Godier, we will explore this concept as well as the possibility of using such technology with alien races, the polar opposite of the classic Star Trek Prime Directive.
Part II of a collaboration with Isaac Arthur on the subject of uplifting, the concept of increasing an animal or alien species' intelligence. Further, we explore the concept of Downshifting, the idea of making deliberately making something less intelligent.
Androids, machines that look and act human, are rapidly leaving the realms of science fiction and entering science fact. In this episode we explore their uses, dangers, ethical dilemmas, and more.
We continue our look at colonizing the solar system by visiting Saturn's moon Titan. We will examine the options for less classic colonization by exploring alternatives to manned colonization and classic terraforming.
A look at methods and concerns for augmenting the human mind. Today we will be looking at Mind Augmentation, the basic concepts, methods, ethical concerns, and possible pitfalls entailed.
It is often thought that if we cure aging or find out how to upload a human mind that humans will be immortal. Today we will examine that notion and see how well it holds up against astronomical time lines.
Today we discuss the concept of trade throughout a colonized solar system, and ask how viable it is and what challenged it faces. While Interplanetary trade faces many challenges, Interstellar Trade faces even more, this episode will seek to examine in detail what can be traded between worlds, what probably can't, and what technologies might impact that.
In memory of Carl Sagan, this episode will review many of the topics he covered during his career and see what what we've learned about the Cosmos and its inhabitants since then.
A look at creating artificial planets, ones vastly bigger than Earth. We return to the Megastructures series to discuss various ways of creating artificial planets, the special issues with making an Earth-like planet much larger or smaller than Earth, and the maximum size they can be, potentially larger than entire solar systems.
Jupiter and its moon are a rarely considered prospect for colonization, but potentially the ripest opportunity for it in the solar system. In this episode of the Outward Bound series we will examine the options for colonizing each of Jupiter's primary moons and even discuss ways to colonize the giant planet itself.
The possibility of Artificial Intelligence turning on humanity has been a concern for as long as we've had computers. Today we will look at some of those fears and see which ones might be valid and which might not be cause for alarm.
The concept of linking many minds together to act in concert, or even fuse into a new singular entity, has been popular in science fiction for decades. Today we will explore the idea and Networked Intelligence in general, to see how realistic it is, and what benefits or concerns might arise from it.
Could the cold outer reaches of the solar system ever be called home? Far beyond even Pluto and the Kuiper Belt is a vast and mostly empty region of space that we theorize may contain trillions of comets and other icy bodies. Frozen and barren though they would be, we will consider how they might one day become thriving and comfortable habitats for us.
The concept of Interstellar Empires has fascinated us for as long as we've know those stars in the night sky were other solar systems, and it's become a staple of science fiction. But rarely do we consider how realistic such galaxy-spanning confederations are, and what special challenges they'd face.
We often discuss the notion of settling the galaxy but do we need to stop there? This episode will examine the additional difficulties with traveling between galaxies and ask just how far we might be able to journey even without faster than light travel.
We contemplate colonizing planets, but what about the stars themselves? Containing virtually all the mass and resources of the solar system, the Sun, the Sun is the ultimate asset for a growing interplanetary civilization. While typically assumed too hot to touch and so out of our reach, we will challenge that notion today.
The End of the World is nigh... how do you escape? This episode will look at many of the potential ways the world might be destroyed, from supernova to asteroid strike, as well as looking at how we might survive such disasters and go about saving civilization.
A discussion of various theories for the End of the Universe. How the Universe began and why is a question that's obsessed humanity for at least as long as civilization has existed, at the same time, how it will end has equally fascinated us. Today we are joined by Astrophysicist Paul Sutter for a two-part episode looking at the science and history of how the Universe came to be and may end.
Ever since we started finding fossils of long extinct species we've dreamed of getting to meet them, either by finding some secluded group of survivors, using a time machine, or resurrecting them. As our knowledge of genetics grows, this last option is fast approaching as a possible reality and raises many additional concerns about the technical and ethical challenges, not least of which is where to put them, with their former environments now used by people or other critters. We will examine these challenges today.
We explore the history and future of missions to Mars. For years following the Moon landings it seemed liked Mars would be our next step and sooner than later, but the costs and risks discouraged interest for around a decade after that. We pick up from part 1 when renewed interest arose and examine many of the more recent plans and what options they give us for manned missions to the Red Planet in the next decade.
We return to the Upward Bound Series to look at spaceports, giant structures dwarfing the modern International Space Station, with a focus on the Gateway Spaceport design.
The idea that alien civilizations may exist but be hiding or asleep is a popular explanation for the Fermi Paradox, the apparent contradiction between the immensity of the Universe and the seeming absence of civilizations in it. Today we exam the concept that civilization may hibernate and what their motives for doing so would be.
A journey out to the stars to colonize Alpha Centauri. We've looked at colonizing our own solar system, from Mars to Venus, and all the way inward to the Sun itself and out to the dark edges of the Oort Cloud. In this episode we conclude the Outward Bound Series by heading to our nearest neighboring star system, Alpha Centauri, and look at the trials and tribulations of colonizing binary star systems and red dwarves.
To explore space and expand beyond Earth we will need a robust orbital infrastructure to serve as our beachhead. Today we will explore the necessary components for that, how we will go about creating them, and threats to them like Kessler Syndrome, a potential cascade destruction of all our space-based assets.
A look at the future of warfare in the void between the stars. Today we will examine the concepts from science fiction of how such conflicts might occur and see how realistic they are under known science.
This episode begins an in-depth look at Post-Scarcity Civilizations, seeming Utopias where virtually anything is available to its citizens at the snap of their fingers. One of the exceptions to that may be privacy, which might be inherently impossible in such a society, and we will explore that challenge as we begin our series on such civilizations..
To see deeper into space, we will need much bigger telescopes. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ As astronomy seeks to find and study distant planets and peer further and more accurately into space and time, the limitations of ground based telescopes, especially optical telescopes, represents our largest barrier. Today we will examine what those limitations are, and ways to make vastly more enormous telescopes and arrays.
The possibility that ancient civilizations might have encountered or even been influenced by extraterrestrials has fascinated us for as long as we knew there were distant suns they might visit from. Today we will examine the evidence and consider the numerous scenarios form the perspective of the Fermi Paradox, to see how reasonable the Ancient Aliens hypothesis is, and ask if the evidence of UFOs visiting us in the past is credible.
The ability to be able to copy or upload the mind has been discussed much in science fiction, and increasingly in science in recent years. Today we will examine many additional uses of Mind Uploading, along with how it works and some of its implications for concepts like Consciousness, Identity, and Individuality. We will also explore how these themes appear in Dennis E. Taylor's newest novel, The Singularity Trap, our Book of the Month.
Today we take a trip inward, to explore Sun-Scorched Mercury. Mercury is the nearest planet to the Sun, a seeming airless wasteland little discussed in conversations about colonizing our solar system. Today we will challenge that, and show that Mercury may be one of the most promising places for humanity to make new homes on.
A look at the possibility of future civilizations rising and falling. It's long been observed that empires tend to rise and fall in a seeming cycle, never identical but sharing many similarities. Today we will examine the idea that this may be the reason that we have encountered no advanced civilizations in our own galaxy, and that the solution the Fermi Paradox, as to why we have seen no alien civilizations, may be that they are caught in a perpetual loop. Unable or unwilling to use technology which might allow them to travel the cosmos. We will also consider if such a loop may await us, or that we are already in it.
Try out Ecosia and support reforestation: https://ecosia.co/isaacarthur Technology may one day grant us a Utopia in which virtually all tasks are performed by robots and artificial intelligence. In such a post-scarcity civilization, people may have difficulty finding a purpose to existence. Today we will explore how this may come about, what the consequences of this existential threat might be, and what purposes people may find for themselves in such a future.

Ceres, a dwarf planet amid the Asteroid Belt, hold the potential to be the hub of a vast mining and manufacturing network in the Belt, as well as potentially growing the food to support future colonists. Today we'll look at colonizing Ceres and asteroid mining, faming in space, and a potential distant future of a developed asteroid belt.
Today we will begin our look at the spaceships we might use for colonizing interstellar space in the future. In order to cover the vast distances between even the nearest stars in our galaxy within the boundaries of known physics, we need vessels able to voyage at high speeds for very long periods of time while carrying everything they need to colonize another solar system, a concept typically known as a space ark or generation ship. We will explore the challenges and options for such a vessel, as well as some alternative approaches to the problem.
For today's 2-part episode we team again with John Michael Godier to discuss the future of humanity should we head out to colonize the galaxy and find it empty, and how we might end up encountering aliens even then.
Part II of a collaboration with Isaac Arthur on the possibilities of a galactic human future and what that might entail.
Beaming energy down from satellites in orbit to replace the production of electricity on Earth may solve many of our problems, and avoid a potential economic or ecological crisis such as energy bottlenecks or global warming. Today we will explore how wireless microwave transmission of energy down to rectennas may not only be possible, but could be massively profitable in the near future and spur our exploration and colonization of space.
In order to colonize the galaxy, we are going to have to spend huge times on board equally huge spaceships. To move thousands of people, and our ecosystem, to distant planets, will require not only giant ark-like starships, but entire fleets of them. Today we will examine how we could do this even if physics never offers us any superior methods in the future for covering the void of interstellar space faster.
Today, we're discussing 5 plausible ways that the world could end, and I'm thrilled to be doing this as a 2-part collaboration with the one and only Isaac Arthur. Check out his video here:
Today we team up with Joe Scott to discuss 5 catastrophes that might threaten humanity in the future, and what we can do to prevent or mitigate them. Here in part 2, we will look at ways of dealing with those threat, which will include artificial intelligence, global warming & climate change, asteroids & comets, gamma ray bursts, and the eventual death of the Sun.
Since the advent of technology, there have been concerns about it replacing jobs and leaving people without an income. Technological disruption has often eliminated entire industries. However, new fields of employment have always arisen to replace those, typically focusing more on training and skills, as machines have no minds and little flexibility. While artificial intelligence may one day change that, today we will examine what sort of jobs might be available to people in the future.
In order to do serious exploration and colonization of space, we will need a source of food beyond Earth. But can we go beyond simply small hydroponic gardens to entire vast space farms in orbit of our planet, and could those farming on satellites and space stations eventually replace earth-based agriculture as our main food source at home?
Alien puppeteers arriving on UFOs, body snatchers, and mimics are a staple of science fiction, but are they realistic? Today we'll examine these concepts and see if they might be possible under known science, or what similar scenarios extraterrestrial evolution or technology might be produce.
In order to terraform new planets, we will need to be able transport entire ecologies & ecosystems through interstellar space in the future. Today we will examine how we could build and maintain such environments inside vast arks, generations ships able to colonize our galaxy, and the challenges these starships will face maintaining not just stores of DNA and genetic material but living organisms which depend heavily on other members of their species and other species to survive and thrive, not least of which is human ourselves.
Drones are becoming more common for military, commercial, and recreational purposes, today we will explore how these will impact us in the near future and far, for peace and warfare, on Earth and in the void of space. We will also examining the fundamental differences in the problems and challenges drones represent compared to more mentally sophisticated artificial intelligences or robots.
The Icy Giants, Neptune and Uranus, are often overlooked for as candidates for colonizing our solar system. Even when noted, the focus tends to be on their larger moons like Triton. Today we will challenge that notion by looking at way we might place a colony on the planet itself, and how Orbital Rings and Chandelier Cities might let us colonize any gas giant. We will also look at how helium-3, a core ingredient of aneutronic fusion abundant on Neptune, might serve as the fuel of future starships, and the physics behind some other starship drives future science might give us access to, such as laser propulsion.
We often worry about the possibility of a civilization developing methods of brainwashing to indoctrinate its population and turning into a totalitarian dictatorship. We will examine both existing and possible future methods and technologies for mind control, such as neuro-hacking and genetic programming, as well as the possible defenses against such brainwashing or conditioning and implications it has for civilization.
Our first end-of-the-month livestream Q&A session, with hopefully minimal technical glitches. Join us 2pm EST, Sunday, Sep 30, and get you questions about the channel and episodes on chat to be answered!
Our seas and oceans have long been central to human civilization, while at the same time we built dikes and islands to reclaim land. As technology improves, we may see even more ambitious efforts in the future. In the episode we will explore the options, both for ways we may extend our civilization to the sea and the motives of doing so. We will also look at seasteads and seasteading, artificial islands built in international waters with the intent of being new, sovereign nations.
As we continue our look at Generation Ships, vast vessels designed to carry many thousands of colonists to distant and alien worlds centuries away, we must ask just how far and how long such ships can be made to last? Can space ships be made that will endure even longer voyages of thousands or even millions of years in the void of interstellar or even intergalactic space? Will ships, and their crews, fall apart or turn into Cargo Cults who no longer remember how their technology functions or what their mission was?
Our seas and oceans have always been central to our civilization, but only the thin layer at the top. In many ways the ocean depths remain more of a mystery to us than distant worlds. And yet, they may be of great value to us as future homes for humanity.
A look at environments and ecology on truly massive space stations. As we expand in space and build ever large space stations, true space habitats, we will need to incorporate ecosystems into them. However, such space habitats will have their own weather and cycles unlike those of Earth, and we will need to adapt to those unique conditions, which will vary by size and type. Today we will look at everything from smaller rotating habitats like Kaplana One and O'Neill Cylinders to vast structures such as Ringworlds, Supramundane Planets, Mega-Earths, and see the unique challenges each of them will offer us in the future.
Our second end-of-the-month livestream Q&A session. Join us 2pm EST, Sunday, Oct 28, and get your questions about the channel and episodes on chat to be answered!
Lifespans have been slowing increasing as medical technology improves, but could they extended massively or even indefinitely? We will explore the science of aging and Strategies for Engineered Negligible Senescence, SENS, the field looking at how to improve geriatric medicine to extend our lives and possibly even makes us biologically immortal.
Our deserts have been slowly expanding, consuming arable land and neighboring ecosystems. Can we push them back, or even turn them into lush oases and fertile farmland? We will investigate the available options, and consequences, with both modern technology and those which may emerge in the future.
The Fermi Paradox asks us where all the alien civilizations are? Today we will ask if the might be hiding in the Voids, from those between the stars to the massive Supervoids like the Boötes Void. Could they be home to Extraterrestrial Empires so large they dwarf even Kardashev-3 Civilizations?
A Moon Base may be built within a generation, but long term colonization will take many more. As more people travel and immigrate their, establishing more lunar colonies, tension between them and Earth could lead to conflicts and possibly even warfare.
To journey across the stars requires voyages of centuries or more, ensuring the crew will be long dead by the time they arrive. If you want your crew available to colonize new worlds after their interstellar voyage, you either have to extend their lives, train their descendants, or freeze them till they arrive. We will examine the third option day, freezing people with cryonics, using hibernation, or suspended animation, or some other form of stasis the future might offer.
Our planet is so enormous that it can often appear flat to those living on it, as time went on and we determined it was a sphere, many still chose to assume it was a flat disc. While this notion is outdated, it is possible to construct an artificial planet as a discworld, and such worldbuilding shapes may have some advantages over a sphere. In this episode we will examine a number of Flat Earth models and some variations on the theme, and see what advantages and disadvantages they have, along with the challenges in constructing them
Our third end-of-the-month livestream Q&A session. Join us 7pm EST, Friday, Nov 20, and get your questions about the channel and episodes on chat to be answered!
So often expanding into space can seem like a Catch-22, where every proposed idea for development can only be practical if space is already developed. Today we'll take a look at some potential options for pushing forward our orbital infrastructure such as asteroid mining or power satellites, and take a look at what other technologies and industries might start the avalanche to our future in space and on other planets.
Humanity has long had outposts in the barren tundra lands of the arctic, but only in recent times have we visited the poles or the entire continent of Antarctica. In this episode we will explore how me use technology in the future to make cold permafrost into verdant farmland through greenhouses, solar mirrors, geothermal, or other techniques, as well as how we might follow a different path, and adapt our civilization to prosper among perpetual winter and ice.
To ring in the New Year, we're joining up with Kaspersky Lab's Earth 2050 project to make some predictions about how our world will change over the next generation as we make improvements in technologies on medicine, data storage and manipulation, and robots & AI.
Revolutionary improvements to automation and production may one day create machines able to produce almost anything, quickly and cheaply, and far faster and more varied than modern 3D Printers. Such devices are sometimes known as Santa Claus Machines, Cornucopia Devices, or Clanking Del-Replicators, and today we will examine how likely such technology is, how far off in the future they might be, and what impact they would have on society.
The galaxy is a vast place with billions of potential new worlds for humanity to colonize, but interstellar space is so enormous that reaching even the nearest stars and planets by spaceship would take decades at best, and maybe many centuries. Even on arrival terraforming those barren planets would take just as long. Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars.
35 years ago, Science Fiction's Grandmaster, the late Isaac Asimov, made some predictions for 2019. As we head into the New Year, we'll take a look at those predictions and see what he got right, what he got wrong, and what it tells us about trying to predict our own future, 35 years from now.
Many believe humanity's future lies among the stars, colonizing distant planets around alien suns, or perhaps building artificial worlds, space habitats, and megastructures. But what if instead of traveling to worlds far away in outer space we create virtual worlds to live in instead, colonizing inner space? We will explore this possibility of simulated universes and what it might mean for humanity, and also ask if this might be a solution to the Fermi Paradox, the strange absence of other life in our own universe.
Without the Sun our world would be a frozen wasteland, and for this reason any efforts to colonize the galaxy must focus on huddling in the tiny oases of warmth around stars, separated from each other by enormous gulfs of interstellar space. But what if we could make our own stars at the places of our choosing? And can we merely mimic nature or create stars unlike anything which nature has formed?
Historically humanity has often taken shelter in caves or underground, and it is often thought we might do so again, on other worlds, in event of disasters, or simply because we run out of room on the ground above. In this episode we'll explore the concept of building underground, from simply subways and basements to advanced bunkers or entire cities beneath the Earth.
Our monthly livestream Q&A session. Join us 4pm EST, Sunday, January 20, and get your questions about the channel and episodes on chat to be answered
Many a land was settled by exiles and prisoners, and many a science fiction story contemplates that we may use such methods when colonize new worlds. But are such methods viable? and what methods might we use in the future for dealing with criminals?
The Dark Forest Theory is a proposed solution to the Fermi Paradox from Cixin Liu which suggests all alien civilizations remain intentionally quiet, hiding from SETI efforts and possible hostile civilizations. It also argues they may attack any civilization which does not remain silent, like us.
Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we'll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source. We will explore the impact this concept would have on the Fermi Paradox if true.
The galaxy is an immense place, with billions of solar systems to colonize, and interstellar voyages to even nearby stars can take centuries. In order to explore and settle those new worlds, we may wish to take advantage of a type of generation ship that stops at planet after planet, colonizing each in turn, and entire colonial fleets that grow as they venture outward from Earth, creating new spaceships as often as terraforming new worlds.
To celebrate Valentine's Day, we'll take a look at relationships in the future, both the romantic and platonic friendships. We'll see what options and challenges might lay in store as we have to tackle the rising effect of social media and online dating, as well as more advanced technologies like virtual reality, artificial intelligence, cloning, and life extension.
Today we're joined by Fraser Cain of Universe Today to discuss the future of astronomy, how you can get started in it as a hobby, and a wide-range of other topics.
Humanity has long wished to dwell among the clouds, today we'll look at what options we may have in the future for floating a city or home high in the sky.
Our monthly livestream Q&A session. Join us 5pm EST, Sunday, February 22, 2019, and get your questions about the channel and episodes on chat to be answered!
The possibility that aliens might be regularly visiting Earth is one of the most popular Fermi Paradox solutions. In this episode we will look at UFOs and flying saucers theories and arguments, as well as examining the logic and possible motives of such extraterrestrial visitors.
The Galaxy is an enormous place, and moving from your planet to worlds in a different solar system over vast interstellar distances will be no easy voyage. Today we'll consider how someone would go about hitchhiking around on spaceships, as a tribute to Sci-fi's master of humor, Douglas Adams.
A new paper has come out discussing how the Fermi Paradox might be explained by the rigors of traveling space for interstellar colonization, causing settlements to be rare and and possibly not long-lived. We'll look at this model for spreading humanity out across the galaxy and see what insights or flaws it might have.
Science Fiction often presents us technologies that go far beyond the realms of known science, but many of these, such as force fields, inertial dampeners, anti-gravity, or faster than light travel might be possible if our future knowledge of physics holds some surprises. Today we will look at many technologies that are currently fanciful but may not be ruled out, what we call Clarketech, and consider what their implications would be if we could get them working.
One of the biggest reasons for colonizing other worlds is to ensure we don't die with our own sun, but even those alien suns we might travel to will die one day. And yet, our image of stars living than erupting spectacular as a red giant or supernova, present a somewhat false impression, as those stellar remnants often last far longer than the stars which bore them. Could civilizations survive around these dead stars? Could they even outlast the End of the Universe, as the last stars fade away?
Earth has often been compared to a spaceship, one that's successfully orbited our star and the galaxy many times over billions of years. So what about moving our planet or even converting it or another world into a spaceship? Can we use entire planets to cross the intergalactic void to settle planets in distant galaxies or superclusters? And what sort of engine and drive could move a whole planet?
Our monthly livestream Q&A session. Join us 4pm EST, Sunday, March 31, 2019, and get your questions about the channel and episodes on chat to be answered!
Fears about technology and it's impact on our civilization, or on individuals even when new tech is net benefit, are often shown to us in fiction as giving rise to technophobic cultures that abandon science. Today we'll take a look at such concerns and if they might be common or rare, rogue examples. Or if, counter-intuitively, they benefit us in settling the galaxy in the future.
Perhaps one of the most common technologies seen in science fiction is anti-gravity and gravity manipulation. Today we'll examine if there's an scientific pathways in physics to permit such technology, and what sort of amazing options it might offer if developed in the future.
To celebrate International Pet Day, we'll take a look at what the future might have in store for our furry friends, and what sorts of new pet might emerge as technology improves.
Giant Robots, or Mecha, in films and comic books fascinate audiences, but are usually considered impractical even with improved technology in the future. Today we'll look at them and concepts like power armor and exoskeletons and see if such suits might have a practical role in warfare or uses other than comba
The galaxy contains countless billions of planets we might colonize, and we may build far more living area as space station habitats and megastructures, but Earth will always be unique and living here prized. Today we will see what we can do make Earth larger, by adding many layers of terrain in concentric spheres around us.
The End of the World is a popular topic in science fiction and a source of serious worry for modern civilizations. If Doomsday comes, what can a Prepper do to survive and what would those civilizations look like? How long would recovery take and what technologies would remain? Just how grim is such a possible future?

Black Holes are often considered the greatest dangers to spaceships in science fiction, but they may turn out to be the perfect power source for future spaceships.
The option of using floating platforms, balloons, or cargo air planes to launch rockets into space and save fuel is often discussed but rarely employed. Today we'll look at stratostations, rockoons, and other suggested methods for getting into space using these methods.
Natural disasters can topple civilizations, even in modern times, but with more and more technology civilizations become more robust and capable of predicting future calamities and preventing such ruin. So what other threats face spacefaring civilizations, both at the interplanetary and interstellar scale?
Nuclear Fusion holds the potential to free us of so many of the constraints offered by everything from fossil fuels to renewable energy option like wind and solar, if we can just get it working. Today we'll look at the challenges facing us in terms of the physics and engineering, the various possible reactors like the Tokamak, Poylwell, NFI, and more, and see what a bright future fusion might offers us. Check out the Butterfly Effect: https://watchnebula.com/isaacarthur
In the future humanity might build structures of incomprehensible size and splendor, megastructures and artificial worlds, but somebody is going to have to build and maintain these feats of science and engineering and clean up all the orbital debris.
It's popular to say nothing is impossible, especially in regard to the future and our Universe, but are there somethings which might turn out to be impossible or at least so impractical they never occur?
Science fiction delights in showing us brave adventurers boarding abandoned spaceships, exploring ancient alien worlds and space hulks, or surviving on planets turned into giant garbage dumps, but how realistic is this idea? And what sort of civilizations and cultures might spring up around such efforts?
A Paperclip Maximizer is an example of artificial intelligence run amok performing a job, potentially seeking to turn all the Universe into paperclips. But it's also an example of a concept called Instrumental Convergence, where two entities with wildly different ultimate goals might end up acting very much alike. This concept is very important to preparing ourselves for future automation and machine minds, and we'll explore that today.
Humanity has a long and inventive history of sports and games, and the future will offer us many new options for athletics as we move out in space, be it racing around the Moon, climbing the mountains of Mars, hang gliding on Venus, or zero-g gymnastics. We'll also explore potential challenges and opportunities offered by genetic enhancement, cybernetics, and virtual reality.
Colonizing Mars and terraforming it to be a comfortable future home for humanity is quite the challenge. How would we go about it and how close is close enough for our purposes? How would we let life grow on the open surface of Mars and how would we give air and water and potentially even alter its day, year, and gravity?
The Fermi Paradox ask us how in a Universe so vast and ancient we seem to be the only intelligent civilization around, with no older interstellar alien empires visible in the galaxy. But could extinction play a role in that, or might extinction events instead drive evolution forward?
Discussion of advanced extraterrestrial civilizations often hinges on the idea that they may have ascended to a higher state or higher level of reality, and lost interest in us and the rest of the galaxy. While we can't know what technologies or enlightened paths they might have available, we can ask how realistic the portrayals of those aliens might be, and if this notion make sense as a Fermi Paradox solution.
There's many dangerous places on Earth, and everywhere off Earth is downright lethal, from the emptiness of space to the airless and radiation soaked Moon to the smoldering inferno of Venus, humanity can't visit them without protection. We'll see what options for spacesuits are under works and what options might emerge for even better ones in the distant future.
Venus is a desolate scorching world on which no life can exist. Yet if it can be cooled down, there is no other planet we know of more suitable for terraforming and colonization. We will examine methods of cooling Venus down and preparing it to be settled in the future.
When people get lost, stranded, or stuck in dangerous situations, we go and rescue them. Today we'll look at what new dangers may face us in the future and what new tools technology might offer us to improve survival chances.
The Butterfly Effect is the principle that notes that even the smallest actions can have sweeping effects on everything in the long term. Today we'll look at that effect and ask what it means toward chaos, inevitable events, fate, and free will itself.
The ability to link mind and machine has long been the realm of science fiction, but now improvements in our understanding may allow us to network brain to computer in the near future. Companies like Neurolink have begun to explore how to link our neurons to machine, and we'll explore now such neural interfaces might function and how they might change our lives.
The Fermi Paradox, the big question of where all the aliens are, has many proposed solutions focusing on what might lower the odds of intelligent species arising on another world, or what might end technological civilizations or cause them to go unseen by us and our SETI efforts. But what if intelligence rarely leads to technological civilizations in the first place? Could there be countless planets in our galaxy occupied by species who never came to value technology?
Cloning people is a staple of science fiction, and now something science can do, but what are the future social and legal consequences of cloning, and can we learn to make fully grown clones or even duplicate our memories?
Every age produces new wonders and new challenges, and for the information age one of those is cybersecurity. We'll attempt to demystify the topic and explain some of the core concepts of keeping your computer secure and your personal data private.
From the most basic rockets to future ships designed for interstellar or even intergalactic flight, spaceship design is all about mission purpose, available technology, and keeping your crew safe and comfortable.
We often consider interacting with Aliens and Robots in the future, but what about Alien Robots? Today we'll ask what artificial intelligence created by aliens might look like and what sort of circumstances we'd encounter them, and if they may be the only aliens we ever encounter.
The Fermi Paradox asks why we don't see any alien civilizations with our SETI efforts. The Late Filters are common solution suggested, that intelligent species may often arise but either destroy themselves or unwilling or incapable of interstellar travel to reach new worlds and colonize the galaxy.

H.P. Lovecraft is known as the father of the Cosmic Horror genre of fiction. The creator of Cthulhu and many other terrifying dark gods in his novels paints a bleak and decaying view of our world and the Universe. Today we'll examine what it might imply if that nihilistic and grim view of reality was correct.
We often wonder how we might first meet extraterrestrials, picturing flying saucers and UFOs landing and aliens emerging asking to be taken to our leader - but joining the galactic community might be a very strange experience.
All of our civilization exists only a thin layer of Earth's surface, and our deepest mines barely scratch our planet. We often talk about finding new mineral resources on other worlds or asteroids in the future, but are we ignore a treasure beneath our feet, and what other technologies and engineering might we utilize in Earth's depths?
We often accuse people of being paranoid about extraterrestrials, flying saucers, and UFOs - but what if it's the aliens who are paranoid?

Is time travel possible, and if it is, what sort of civilizations would result? We'll explore the science that might permit it as well as the classic science fiction examples to see if they make sense.
Alien Conspiracy theories are too numerous to count, but are they simply being paranoid about UFOs or might aliens be conspiring against us? Alternatively, could an extraterrestrial civilization be conspiratorial by nature, and what motives might a galactic civilization have for involving themselves with us in secret?
Fire is often considered the foundation of human technology, but there may be many worlds on which it would not be likely to practical, such an ocean planets, and on which intelligent life like Dolphins might emerge. Could such worlds host technological civilizations anyway? Or would they be forever stuck at little to no technology?
The Moon is gateway to space, and in the future it might serve as an industrial and mining complex fueling vast production of spaceships, rocket fuel, satellites, space stations, and colonial habitats.

Mankind's future is among the stars, but not necessarily on other planets. Instead we might forge giant space stations that are entire artificial worlds, and today we'll explore some of those megastructure designs, like the McKendree Cylinder, Bishop Rings, Banks Orbital, Topopolis, and more.
Science fiction loves to show us disembodied heads or brains floating in jars, but could this be one route to extending our lives? Or could you already be one living in false reality?
Our future lies out among the planets and stars, but to climb out in to space we must take many steps to get off, and today we'll look at those first steps to becoming spacefaring species. From cheaper rockets & space stations to asteroid mining & defense to space tourism & commercialization, we've a long road ahead, but we have a roadmap.
Our solar system contains many planets, moons, and asteroid that we may one day call home, but the future might instead be artificial space habitats, stations, and megastructures of vast size and numbers, using all those celestial bodies as raw materials to be dismantled for construction.
If the Universe is inhabited by older alien civilizations, those who have ventured out to the stars and colonized galaxies, we would expect to see a footprint of extraterrestrial activity. Could the many stars whose brightness has dimmed be indicative of Dyson Spheres or other Megastructures? Could the Cosmic Voids vastly bigger than any galaxy be the work of even greater and older starfaring species?

To travel to other planets, we will first have to build up are infrastructure closer to home, in orbit of Earth. The best place to get all the mass for those space stations and rocket fuel depots is from the Moon, and we'll examine the milestones we'll need to reach to start lunar resource harvesting and building up space settlements.
Asteroids represent a serious hazard to Earth, past, present, and future, but will be even more of a concern to humanity as we venture out to space beyond beyond our atmosphere's protection. We will explore what technologies and methods may be available to help protect us from asteroids.
Nuclear Fission was once hailed as the solution to our power & energy needs, but has grown unpopular of fears of radiation, meltdowns, and radioactive waste. However, advances in science and reactor design may make atomic energy safer and more attractive in the future.
The genesis and origin of life may require a very rare and delicate mixture of certain chemicals. One of those is phosphorus, and trying to figure out how we ever got enough of it in Earth's primordial soup for life to form in the first place has long puzzled scientists.

It's been over half a century since we first went to the Moon, and nearly as long since we last went. To Return to the Moon we need a base with a purpose, and we'll look at what purposes we have in mind and what the bases might be like as we head back to establish a Lunar Colony.
Science Fiction delights in showing us grim, dark, giant, and dystopian future cities of covered in garbage and where life is cheap, but how realistic are such metropolises and how can we avoid living in them?
Recently the Military released Navy footage of 3 separate UFO or UAP - unidentified aerial phenomena - we will review that footage and consider both mundane explanations and the not-so-mundane, like secret projects, extraterrestrial origins, and what it might indicate about the technology and motivations of such alien civilizations if they are visitors from out in the galaxy.
We typically imagine interstellar civilizations as vastly superior in technology to modern times, but could the future see planets colonized by spaceships little better than our modern ones? Could some alien worlds allow space travel to develop far sooner and easier than it did on Earth? Or could civilizations abandon more advanced technology?
To become an Interplanetary Species we need to colonize another planet, and Mars will be our first target. To establish a base there, and a future settlement, we need to get their first, so we will also examine the Aldrin Cycler, a type of spacecraft that may make traveling to other worlds far easier.

Aliens are portrayed in Science Fiction both as our potential saviors and best friends, as well as the stuff of nightmares. Would an extraterrestrial civilization be benevolent or terrifying, and how would we seem to them?
The Kardashev Scale measures how powerful a high-tech civilization is, with K-1 indicating a advanced society able to call on all the power of their planet, which we often envision as a Post-Scarcity Utopia. Is this the future of Humanity? And if so, how can we achieve it?
Establishing Interstellar Trade and Commerce in the future will require an entirely new approach to moving cargo, as years if not centuries might pass for shipments to arrive by even the fastest spaceships, but may be aided by the use of vast interstellar Cycler Castles traveling on century long trade routes.
One solution to the Fermi Paradox, the big question of where all the aliens are, is that extraterrestrials might hide from us to avoid altering our society, a concept we see in Star Trek called the Prime Directive. Is such a policy ethical, and if so, should we follow it?
Asteroids represent a threat to Earth, but in the future they may be a boon, serving as sources of vast wealth and resources, and as orbital settlements and keystones of interplanetary trade.
In order to colonize space, we will need colonists willing to travel to desolate planets, moons, and asteroids to settle those worlds. What would life be like as a pioneer to the alien frontier?

Machines may help bring about a Post-Scarcity Utopia, assuming they don't take over instead, and we dream of a future that is a Post-Scarcity Utopia, but its dark reflection is the Post-Discontent society, one where through deception or brainwashing people do not even known how they are being deprived or oppressed.
Water is one of the most common substances in the Universe, and Earth has far more seas than land and life arose in the ocean first. Planets covered entirely in water may be common and abundant with life, including intelligence extraterrestrial life.
For every yellow star like our own there are ten times as many smaller stars. Red Dwarfs are the most common type of star, outnumbering all the others combined, and as we head out into interstellar space to colonize the galaxy, the exoplanets around these red alien suns may be the most common home for settlers.

Many believe humanity's climb upward may have been assisted by outsiders. Is this possible, and if so, what does that tell us about our own past... and future?
Technology has shaped our civilization as it grew down the centuries, and since the industrial revolution, each new generation seems defined by some new technological revolution… So what will the next revolution be?
In the future, fleets of unimaginable scope may battle over light years, in conflicts that might last milliseconds or entire centuries.
Could something in the future alter the past, so that effect came before cause? Does quantum mechanics truly allow this, as often hinted?
The Moon is barren and lifeless, but as we return to the Moon and settle there permanently, might we transform the brightest jewel in our sky into a glittering emerald full of life?
In the future, we may colonize other planets or build artificial worlds for people to life on, but some may choose a nomadic life on spaceships instead.

One day we will journey to the Red Planet and perhaps settle there, but what great civilizations and cities will emerge on the red sands?
In the future we may have technologies sufficiently advanced that they are indistinguishable from magic, but could those civilizations also be indistinguishable from primitive ones?
Many seek a path to enlightenment through study and meditation, but what does science tell us about transcendence? And could entire civilizations seek to leave this reality behind?
Technology brings us many wonders, but it may also bring about the end of our privacy. What, if anything, can we do to protect it?
We often envision filling space with vast megastructures people might live on in the future, and mining asteroids to provide the materials for their construction, but what would life as an Asteroid Miner be like?
One of Earth’s most unique features is the enormous gemstone in our sky we call the Moon, but could the Moon be the reason why we even exist?
Explore the challenges and possibilities of colonizing Io, Jupiter's volcanic moon, as we delve into the extreme conditions, scientific innovations, and potential for human settlement on one of the most hostile environments in our solar system.
Fungus and Protista are far more ancient than animal life, and far more varied in form. So could alien fungi be more common in the galaxy, and might it spread through space by spores?
Humanity has often lived with one foot on land and the other in the sea, but in the future, we may build our homes in the seas, here and on other worlds.
Soon humanity may reach out to the galaxy and spread ourselves to every world in it, but in the billions and billions of years to come on those billions and billions of worlds, humanity shall surely diverge down many roads and posthuman pathways.
An exploration of the unsettling possibility we live in a universe of ancient galactic wars, ruins, relics, and leftover war machines scattered across the cosmos.
