German educational design studio Kurzgesagt turns to a sobering truth of astrophysics: the fact that 94% of the observable Universe is so far from us that we will never go there, even if we achieve light-speed travel. To wit:
…there is a cosmological horizon around us. Everything beyond it, is traveling faster, relative to us, than the speed of light. So everything that passes the horizon, is irretrievably out of reach forever and we will never be able to interact with it again. In a sense it’s like a black hole’s event horizon, but all around us. 94% of the galaxies we can see today have already passed it and are lost to us forever.
And if that twists your melon, consider this: by the time you’ve watched the video, 22 million more stars will have drifted off beyond our reach.
