Science & Futurism With Isaac Arthur

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.

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?

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.

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.

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.

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 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.

There are many reasons not to eat meat, or at least less of it: medical, ethical, economical, or ecological, but the stuff is quite tasty. Today we'll look at how artificial meat technologies in the near future might allow us to produce a genuine alternative to modern methods of standard agriculture or meat substitutes, and maybe even some exotic meats not available at the supermarket.

In order to get into space, we require either huge amounts of rocket fuel or dangerously powerful energy sources, making personal spacecraft a technology limited to science fiction. But by harnessing beamed power sources to run engines, we may be able to create a spaceplane cheap enough and safe enough that anyone could have one in the future.
