Is this why we have Gravity?
A correct theory of gravity will show us these four (4) things:
- It will show us why gravity also acts like acceleration (principle of equvalence).
- It will show us the actual cause of gravity.
- It will show us why gravitational mass and inertial mass are identical.
- It will show us the speed of gravitational attraction.
Newton said gravity was acting at a much faster speed than Einstein. Which one of them was right?
