discover the entire known universe

This is freaking incredible. It makes you feel sooooo small and inconsequential, like maybe some much larger, much smarter civilisation has set up planet earth as some kind of dry run?!

Planet Earth is so teeny in the grand scheme, when compared to the universe. We're just tiny.

How is it possible for scientists to even map this far out? It's amazing. I'm amazed. I need to take a break and make a cup of tea, I'm that impressed.
