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.

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.
