What if the Sun Suddenly Disappeared?

by Kenny Hoeschen

This video from Vsauce explains the frightening consequences if our Sun were to suddenly disappear. Of course, although the Sun will die in a few billion years, it will not suddenly disappear. Still, it’s interesting to consider what would happen in that event. Two things humans are particularly good at would likely occur first: confusion and mass panic. Our only source of light would be from the rest of the universe, much of it from the Milky Way galaxy. That’s equivalent to about as much light as 1/300th of a full moon, not enough to continue photosynthesis. The loss of the heat from the Sun would be devastating to life on Earth; except for those extremophiles that already exist at the bottom of the oceans without sun, surviving on geothermal heat for billions of years, all life on Earth would perish in the crushing cold.
