In my physics class, we learned that everything accelerates towards each other at 6.67 x 10-11. I'm not sure what about that doesn't make sense (We didn't talk about it much, but we're expected to know about it) but something doesn't. How can EVERYTHING accelerate at the gravity? Uhhh, wouldn't a bigger mass go faster? Earth goes 9.8 m/s2, so where does G come in to play? And how the crap did someone figure that out, anyway?
