The Ultimate Fate of the Universe: From Expansion to Darkness

TLDRThe universe is expanding at an accelerating rate due to dark energy. Galaxies will eventually be flung away from us, leaving us in the cosmic event horizon. The expansion will continue until all galaxies are invisible and undetectable. The universe will enter a dark, cold, and sparse void. Supermassive black holes will dominate the universe, until they eventually evaporate. The universe will then be consumed by a gigantic ultra-massive black hole, returning to a singularity. The fate of the universe is uncertain, with options ranging from a Big Crunch to an oscillatory universe.
