Newton saw the apple fall to the ground and deduced gravity was pulling it down, but, what if we are wrong and gravity is pushing the apple down from the tree. Nothing changes to the observer but the force acting on the apple is changed 180 degrees from a pull to a push!
So if gravity is a push we can deduce the force is coming from space, to explain this imagine space is a medium made up of space/time/gravity force in other words an "ocean" like medium.
This medium applies force to all bodies within it (just like an ocean).
Bodies/mass cause a distortion within this "ocean" (
https://ancient-code.com/scientists-...on-space-time/)) such that the bodies are surrounded by a sphere of distortion. The size of the sphere would dictate the pressure (gravity force) exerted at its center, huge for a Black Hole tiny for an atom. The gravity force exerted by the "ocean" will force adjoining spheres together exactly as we observe now.
Things to like about this theory.
Recently discovered gravity waves are easily explained as ripples in the medium(ocean).
There is no need for gravitons, gravity force only works in one direction.
We have evidence for bodies distorting space.
Space being a medium goes towards explaining the speed limit of light (think speed of sound in an atmosphere!)
Worth a thought??
