Godlike Aliens

We believe Mars may once have had oceans and sky, but lost them from a lack of a magnetosphere. How does this happen, and how can we create a magnetosphere for Mars so we can terraform and live on it?

Making a Magnetosphere for Mars

One day humanity might journey to new worlds and settle them, or discover life already on them, but first we'll have to find those exoplanets under aliens suns.

Surveying For Habitable Interstellar Star Systems

Many don't realize that most of our satellites and space stations aren't intended to be far from Earth, but rather, as close as we can get them and still maintain a stable orbit. How much lower can we go in the future?

In the future humanity may build enormous structures, feats of mega-engineering that may rival planets or even be of greater scope. This episode catalogs roughly 100 major types of Megastructure, from those that are cities in space to those that rival galaxies.

The Megastructure Compendium

The Silurian Hypothesis contemplates how long the ruins of a civilization would be detectable, on Earth or even other worlds, and if we could ever know if a world had once been inhabited by a technological civilization.

Science Fiction has shown us humanity exploring the stars at hundreds of times faster than light speed, but what if the fastest ships we can make never even reach a hundredth of light speed? Can we still settle the galaxy and what will that colonization entail?
