comment Is there any limit on movement of space itself?
Every metaphor is imperfect simplification but that shouldn't prevent scientist from explaining concepts to layman. Strangely you don't like the rubber sheet metaphor - I used to think about objects in space as smarties in jello - if they are tunnelling through the jello they are moving. If the jello itself is warping bringing two objects closer or further then they were without them tunnelling through the jello then the space is moving while the objects are not moving. Or is this metaphor too far from reality?

Thanks for the undoing the hate. I am just a layman trying to understand interesting things.

So space can expand, warp, wave, bend, distort but not move. Got it. So is there a limit at which can space move but not move?

comment Mach's principle in empty universe, centripetal force and violation of Newton's laws of motion
I am not a physicist, I was merely reading Wikipedia when I got curious about the absolute rotation question and in there Mach's principle is presented as credible theory, certainly not outmoded like flat Earth. Does that mean that absolute rotation is accepted by mainstream physicists and Mach's principle is considered outmoded?

How is it different? Does the space not move when gravitation waves propagate through it?
