Thats an answer I do not have. We can easily measure the effects of gravity... we know the cause is the mass and distance of two bodies... as to what that force actually IS, well thats a conceptual thought I suppose you will have to decide on yourself.
The problem is, we cannot SEE gravity. We can measure it's effect. And we can predict it, and even use it to figure out where, what size and how heavy other objects are without seeing them.

I'm pretty sure your missing something there too... you're describing centrifugal force, not gravity. Gravity has nothing to do with the spin of an object or the centrifugal force applied to it. Gravity is purely a mass to distance ratio and it's effect on the objects nearby.
don't get me wrong, I'm not putting you down... nobody really 'gets' gravity. we can conceive of it in some forms, but our mind doesnt conceive of things very well if we can't visualise it.

Your right. That doesn't explain the moons gravity since it doesn't have an atmosphere.
Or the suns massive gravity. There's definitely something else going on there with the whole gravity thing.
sheep tents!!!!! wtf, have you never heard of a barn?
