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?

Making a Magnetosphere for Mars

A Galaxy of trillion of worlds, all separated by vast gulfs of time and space, it is very easy for pioneers and colonists to disappear. But what happens to these lost space colonies?

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?

Dark Sky Stations, Stratospheric Satellites, and Ultra Low Orbit Infrastructure

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.

The Megastructure Compendium

Every known planet, moon, and asteroid in our solar system occupies a volume of space both enormous and yet tiny compared to the vast empty gulf between stars. But interstellar space isn't truly empty and may one day be home to countless billions of isolated deep space habitats.
