What happens when the last stars go out?

Long after our sun has died and the Milky Way has faded, what will be the very last light to shine in the universe? The final survivors will be the humble red dwarfs. These small, dim stars are the most common in the cosmos, and they are incredibly efficient, sipping their fuel so slowly that they can live for trillions of years—far longer than the current age of the universe. This short takes you to the ultimate future, an era when red dwarfs will be the only lighthouses in an ocean of darkness. We'll explore their incredible lifespans and what happens when even they, the last stars, finally go out, leaving the universe to a cold, dark eternity. If you've ever wondered how the story of the cosmos ends, it ends with the quiet fading of a red dwarf.
