The Paperclip Maximizer (Narration Only)

Science & Futurism with Isaac Arthur ·

2019/09/01

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. Watch the video version: https://youtu.be/3mk7NVFz_88 Visit our

Space Derelicts

Science & Futurism with Isaac Arthur ·

2019/08/29

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?

Things Which Will Never Exist

Science & Futurism with Isaac Arthur ·

2019/08/22

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?

Fusion (Narration Only)

Science & Futurism with Isaac Arthur ·

2019/08/08

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.

Threats to Interplanetary & Interstellar Civilizations

Science & Futurism with Isaac Arthur ·

2019/08/01

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?

Invasive Aliens

2019/07/25

Alien Invasions have been a staple of science fiction for years, with motherships and UFOs assaulting Earth, but how realistic is such a thing? We'll take a look at what might motivate an attack, how it might happen, what alternatives might make more sense, and what might prevent extraterrestrials from trying.

Boltzmann Brains

Science & Futurism with Isaac Arthur ·

2019/07/21

We continue our discussion of the Boltzmann Brain - a hypothetical randomly assembled mind rather than an evolved one - by looking at the Anthropic Principle and the Fine-Tuned Universe Theory, alternative ways of viewing the probability of our existence than the classic Copernican Principle.

Space Whales

2019/07/18

The idea of spaceships or other machines that were essentially alive and able to repair and operate themselves has long been a popular one in science fiction. We'll take a look today at how that might be possible in the future, what advantages it would have for interplanetary or interstellar colonization, and how it might lead to entire artificial ecosystems dwelling in the void of space.

Void Ecology

Science & Futurism with Isaac Arthur ·

2019/07/14

The possibility of extraterrestrial life on other worlds has long fascinated us, as has the idea of alien life living in space itself, but while the former is often considered quite probable, the idea of anything evolving on airless moons, comets, and asteroids seems less likely. But with scientists uncovering life in ever more extreme and inhospitable environments on Earth, perhaps it is more likely than we think.

Space Tourism (Narration Only)

Science & Futurism with Isaac Arthur ·

2019/07/11

Space is an awesome place filled with virtually infinite wonders to explore, and human colonization will likely make far more. It may soon be possible for people to journey up to orbit as tourists, and in the more distant future this might become a vast trade, with tourism in Space Station Hotels or on the Moon or Mars or traveling to countless other planets, moons, asteroids, or megastructures.
