The End of History

We have a capacity just within our own minds to think of things that we're not thought of hundreds of years from now. So there is a hubris in asserting- That we now know all the- That we know everything. Eventually, they'll be moving away from us faster than the speed of light spanning the gap between them. However many billions or maybe even trillions of years later, someone on planet Earth in the Milky Way would look up into the heavens and see only the stars of the Milky Way held together by local gravity. I can't wrap my head around it.
