Astronomy=Biology?!

I became intrigued we started to increase the spacial scale to bigger and bigger sizes. Before this week, I had never really thought of Biology as consisting of anything bigger than a whale or a tree. I had never really thought of how the cosmos related to and affected the Earth. To put it more plainly, I had never really thought of Astronomy and Biology as being connected. Astronomy to me was just a bunch of stars and galaxies far, far away that didn't really have that much to do with us on Earth. Biology was the study of a bunch of animals and plants and the like.

It is very hard for me to wrap my brain around the fact that the universe has an end. I know it would be impossible for it to go on and on forever (although it seems like it does anyway since it is so big), but I keep thinking "Okay... What's the next thing bigger than universe?" I find it quite hard to imagine that after the universe ends there is nothing. And not just empty space nothing. What would happen if you reached the end of the universe? Is the universe square and you would fall off the edge? (Probably not... But if the Earth was thought to be a cube, then why can't the universe be?)
