Is gravity bent space-time which causes mass to "slide down hill" or is it a push force or pressure that is everywhere the universe that is shielded by mass?

What experiments do or would show which model is correct?

This is only my opinion, not proven or anything.

At first I was thinking it was just a for because of some molecular attraction, but as I think about it more, It seems to me that gravity may be bent space-time. I have come to this conclusion from the illustration of a black hole. It has an immense gravitational field and when it is drawn out, it looks as though a bend in space time, in the same shape as the strength of gravity.

I do not know of any experiments that would show this, but at least it gives you some basis for reasoning on one side or the other.

Remember, this is just my guess.
