Thinking of the Universe makes my tummy hurt

Seriously, I get this weird sinking feeling in the pit of my stomach whenever I think about the universe and how big it is. My brain starts hurting like I can't even conceive its vastness. Yep, there it goes again... stomach sinking... brain squeezing... lungs closing up. How can something really go on forever? But then again it would be just as weird to think that the universe has an end.

On the other hand, have you ever seen pictures from the hubble space telescope? Pretty awesome stuff. I try to look at the pics and just think of how pretty they are and not how big or how far away this stuff is.
