Is spacetime elastic "fabric" that can be displaced and is that what causes curvature and gravity?
Visualization in my head:
Spacetime is like flexible elastic packing foam. I sandwich a ball bearing between two sections of foam. The ball bearing displaces the foam which causes the foam around the bearing to compress. The foam is elastic so it wants to go back to its original state.
Is spacetime being displaced and compressed around a planet? Is that compression what causes gravity and curvature at the quantum level? Like spacetime wants it's space back so it pushes back into the planet. I dunno just thinking.
