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.
