Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. … Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.

And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. … The Universe will be completely dark.
