“The vastness of space truly boggles the mind.”
Yes, I was reading a book this summer, Multiple Universes, by Kaku and he said that astronomers estimate that we can only see a small part of what is out there, that if the universe was the size of a basket ball, what we can see would be only the size of a quarter.
I can’t comprehend the vastness of space, to me, there has to be an end out there like the walls of a box.
