Gravitation is, so far, not understandable in terms of other phenomena.
You think Earth's gravity is really something when you're climbing the stairs. But, as far as physics goes, it is a pipsqueak, infinitesimal, tiny little effect.
The fall of a given weight from a height of around 365 meters corresponds to the heating of an equal weight of water from 0° to 1°.
And I was crying for gravity. It had sent me down the stairs, and I'd thought that meant something, but maybe it was just the direction that all things tend to flow.
We must see whether the same clock with weights will go faster at the top of a mountain or at the bottom of a mine; it is probable, if the pull of the weights decreases on the mountain and increases in the mine, that the earth has real attraction.
I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity.
I need physics more than friends.
