How does gravity work?

Question

Why don't we float off the earth?

Answer 1

Newton's laws, as others have suggested, is a theory describing how gravity operates, but it does not explain where gravity comes from - it merely says that objects that have mass generate gravitational fields. Einstein's theory of general relativity is a similar theory, which says that objects that have mass distort the fabric of space-time. But neither of these theories really explain *why* gravity exists - why do massive objects produce these results? That is unknown.

Answer 2

everything has mass "think of it as weight" gravity is the force between the two masses. The larger the mass, the lager the gravity force it has. So the earth(huge, so huge gravity) exerts it force on you, so the two of you are "attracted" to each other. -in real life it is much more complicated, but this is all you need to know right now.

Answer 3

Gravity is space displaced by matter, trying to return to it's pre-matter shape. The pull is down, where the center of the displacement is. Before too long, someone's going to figure out how to manipulate that effect and we'll have our first gravity drives.

Answer 4

They are trying to prove that gravity waves exist.

Something like light waves but a lot longer.

Answer 5

The answer is because the earth is rotating so quickly that we act like a magnet to it if you could spin a ball fast enough and put dust on it, it would stick

Answer 6

Type "Newton's laws" in a search engine

Answer 7

Too complicated for this forum... but when it comes right down to it, no one really knows.
