What If Earth Became A Rogue Planet?

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?

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?

Our capability to render virtual realities better and better makes it seem likely one day we could simulate our world flawlessly, and perhaps our minds too. If so, perhaps we will in the future... and perhaps we already did in the past.

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.
