Here's a take on what gravity is. It has to do with the big bang theory. That a giant star exploded and in the space that the star existed the "void" because of pressure begins to draw in matter until it has created a ball so big that it still draws in matter but not as strongly.
Now this new weaker force is gravity. And over time the gravity will dissopate and seese to exist until the earth looses hold of itself and disentigrates into space or explodes like a bomb that it could be.
It is afterall a huge ball of matter with mountains of pressure and filled with molten lava. This could all be true yet a very "slow" process.
