Really? How bizzare...

As someone once said,

   "Gravity is far weaker than electromagnetism. To demonstrate this, 
consider a person jumping off the top of a tall building. It takes 60 
seconds for gravity to accelerate your body as you fall, but only 0.08 
seconds for electromagnetism to bring it to a halt at the bottom."

Mmm, messy. :-D
