My favorite related saying is:
GRAVITY:
It's Not Just a Good Idea...
It's the LAW
I don't like to dwell on gravity for too long. It always brings me down.
I independent of Newton discovered Gravity.
This may seem like a bold claim but since I was only 5 years old and never heard of Sir Issac, I think I can firmly claim the right.
I was a tiny child. I secured a rope to a 5 gallon bucket and threw the rope over the top of the jungle gym. I was small enough to entirely sit in the bucket.
My improvised elevator was moved by arm power to the top of said jungle gym. My ascent was relatively slow compared the the speed of my descent.
I in my juvenile mind thought that since I went up slow that I would go down slow when I released the rope.
As I impacted I discovered gravity, the law of acceleration of a falling body and the law of the bloody nose in the same moment.
I completing my body of research in physics decided I did not want to further my studies in this area. I decided that the medical field and the repair of bloody noses suited me better.
The entire universe is exapnding. Gravity is simply the observed effect of the expansion as particles accelerate outward from each other. Hence, things seem to be drawn together, but in fact they are merely getting bigger.
To simplify: Put Michael Moore in a room with a suicide bomber. MM is getting fatter, and the suicide bomber sets off his vest. They seem to be drawn together at different rates, but they are actually simply expanding, each according to their specific physical natures.
