Gravity isnt really a force, it just feels like one.
Acceleration by thrust, like in a car or F22 or Falcon9, IS a force.
But gravity is just space “flowing” toward matter. If something is blocking you from going with the flow, that blocking feels like a force.
All of space is always flowing toward all the matter in the universe, moderated by 1/distance(squared). If apple A is twice as far away as apple B, the gravitational attraction (flow) is 1/4th as strong.
And gravity “waves” as detected by LIGO from orbiting colliding black holes really are waves in the flow.
Crazy universe this is.
.....
Gravity.
It’s not just a good idea...
It’s the law!
IMHO...
Of course it is a universal law/force, but no one can figure what it exactly consists of.
