That's the idea of locality. Spacetime locally works about the same everywhere. If you are in the same gravity well, or travelling at the same near-light speed as something else, the stuff around ...

Home > Extreme Spacetime curvature measured using a vanishing star As one star spins another out of view for the next century and a half, astronomers use it to weight an incredible binary system.

Spacetime curvature is generally represented by a downward funnel poked into a 2-dimensional sheet, the weight of ball bearings on a trampoline.

Gravity is the curvature of spacetime, and massive objects create significant curvature. The experiment utilized this fact of time dilation to measure the amount of spacetime curvature in “ ...

It is also shown that a four-dimensional spacetime with divergence-free semiconformal curvature tensor admitting a proper semiconformal symmetry is locally of the Petrov type O or has four distinct ...

But of course, when it comes to a theory of real gravity, or general relativity, larger masses will determine space-time curvature and space-time curvature will determine what counts as free fall.

A team of researchers working at Stanford University has used time dilation in an atomic fountain to measure the curvature of space-time. In their study, reported in the journal Science, the group ...

However, the more accurate measurement of gravitational redshift provides more constraints on the curvature of space-time, which may influence the development of a theory of quantum gravity.
