Pretty confusing, right? I took two semesters of university-level astronomy/astrophysics, and I still can't wrap my mind around some of this stuff. :/

No I understand it. When I was a teenager my buddies and I would go down to Chinatown and do a straight line straight to the buffet. We would eat like pigs and then go to the bathroom and puke. Whereupon we would come back and start over at the buffet table thus returning to our starting point.
I just didn't know it had to do with gravity. Thought it was the mushrooms we had before heading down the hill but you live and learn every stinkin day!!!!!!!!!!!!
