Have you ever thought about the endless universe and how it goes on and on and on, infinitely? How does something continue to go on and on and on without ending? But then, try to imagine the idea of the universe just ending, like you get to the edge of it and then there is just nothing. But what is nothing? It's hard to imagine nothing! So I try to think about the universe never ending but it just boggles my mind too much. So then I just don't think about it anymore until I think about it again.
Do you know what I mean?
