Wann müssen wir die Erde verlassen?| Grenzen des Wissens

The sun is getting hotter over time and will eventually become a red giant star that will swallow the Earth. At some point, we will have to leave Earth. Energy and technology are the keys to our long-term survival. If we reject this, we will go the way of the dinosaurs: waiting for extinction.
