Hey, I am an accountant so when it comes to science I am like ~duh...

The simplest explination of gravity ever! Put a ball on your bed and then stand next to it so it rolls toward you. Basicly the same thing happens with large objects in space they bend space times so things go toward them. As with the ball the futher away you stand the less gravity effects it.

Anything that has mass has its own force of gravity that it exerts on everything else. Of course, more massive objects exert more gravity. So the next time you pass by someone heavier than you, you'll know why you suddenly just fell over! (jk)

As one of my teachers used to say, "There is no gravity. The Earth sucks."

you may be thinking of the EMF emitted from earth. Gravity isn't really fully understood, though I did have a physics professor suggest to us once (from his work I guess) that the story might be on a subatomic level. I won't try to explain, as my physics understanding stops at clasical physics, though I know there are plenty of smart physics experts here who probablly can give u a modern physics outlook on it.

Wow. Thanks for all the responses. Strange stuff. I was going to ask if its similar to magnetic attraction, but then I realized I don't know anything about magnetic attraction - so that would have been a pretty stupid question.

Sometimes its boggling how little I really know about whats going on around me.

Magnetic attraction (explained by Maxwell's equations) is where my understanding of physics ends... that stuff is pretty crazy, too. When you start examining induced EMF's and induced magnetic fields, it makes you wonder how the world isn't a mess of magnetism from all the moving electric charge we use to power our lives. I'm really looking foward to my modern physics class this fall when I learn about relativity and quantum mechanics to get a better grip on the theory behind some of this stuff.
