Stars won’t last forever, but civilizations might. Join us as we journey into the post-stellar future, where Dyson remnants, black holes, and exotic physics could sustain life long after the galaxies fade.

Does the Universe stay quiet because alien species burn through fossil fuels and collapse? We explore alternative energy paths and ask if civilizations are doomed by geology.

Superpowers make great fiction, but evolution doesn’t work that way. We explore why mutations can’t give us instant abilities—and what real science could create instead.
