From the point of view of our descendants 100 billion years from now, there’ll be nothing left in the universe apart from our local group of galaxies, which by then will have merged into a supercluster. We will be entirely alone in an endless ocean of blackness. In about 100 trillion years our local stars will have exhausted their fuel supplies, and the supercluster will then eventually collapse to form a black hole. At that point the show is over.
