has anyone even figured out what gravity is?

Bingo. Science has no explanation for electricity, magnetism, and gravity. It can predict their occurrences and measure them, but has no way of explaining what exactly they are.

thanks, that's what I thought

[Dead Corpse]

Wrong oh Mighty Brain-bot. Electricity and Magnetism are well known.

They are working on gravity. Give 'em some time.

Jeez, you don't think the world is flat do you?

In science, things are exactly what can be measured/determined about them. For example, an electron is a particle with certain mass, charge, spin, and quantization potential properties belonging to a class of particles known as leptons. That is exactly what "they are." To ask for more goes into the realm of philosophy and metaphysics. The latter realm is generally unproductive and unreliable, imho.
