Only one tiny thing they forgot to mention in the article: No one knows what gravity is.

Of course I should add my usual disclaimer:

What I don't know about physics could fill a book. (Hundreds of them, actually)

I was told in high school that gravity didn't exist...the world sucks. Since then, coomon sense tells me that gravity does not 'pull', it pushes. HOWZAT?
