Well Greathobo, Just exactly HOW does "massive amounts of mass" causes gravity?

Scorpion, you do have a point, but please explain what makes gravity a force?

The old professor says: Einstein sort of envisioned space like a cube made of fabric threads....like take a stack of bed sheets and then run threads vertically down through them. Now you have a block of cloth instead of sheets. In other words, you have an X,Y,and Z axis. This is what we call the "fabric" of space.
He said that mass can cause these threads to bend. Instead of a cube of space, lets just take a sheet...again, like a bed sheet. Now put a marble in the middle and note how it kind of dips down int the middle. Now put a bowling ball in the sheet and see how it REALLY sags in the middle. The more mass, the greater the sag...the more gravity, the greater the curve in the threads. So...to answer your question....matter is mass, and gravity is a property of mass and is directly proportional to the mass. The more mass, the more gravity, the greater the curve in the fabric of space.

Both, indirectly, gravity causes curved space. Massive amounts of mass cause gravity.

All matter curves space. The curvature of space results in a phenomenon we call gravity.

Gravity - how would matter? Gravity has a force.
