“I realise now that I wanted to disappear. To get so lost that nobody ever found me. To go so far away that I’d never be able to make my way home again. But I have no idea why.” -Jessica Warman
When you think about the galaxies up there in the night sky, only visible with the most powerful telescopes in the world, it also behooves us to think about how incredibly rapidly they’re moving.
As the Universe expands, the space between us and them expands as well, causing an incredibly fast apparent recession. It also means that these galaxies, given enough time, disappear from the farthest regions of space we’ll ever be able to reach. In other words, as time marches on, the number of galaxies reachable by us continues to drop!
How many are left? And how quickly are things disappearing? Go read the whole thing and find out!
