Contradiction of propagation speed of gravitational waves with non-locality of gravity?
Although LIGO at 2016 verified the speed of a traverse gravitational wave being the speed of light in a vacuum $c$ there is also the fact that gravity is a non-local phenomenon, meaning that it is not ...

Nonlocal Gravitational energy: How to localize nontrivial topology in GR?
Ok, This question has been beaten to death. I just wanted to look at it from a slightly different angle: Einstein, Rosen, and later Wheeler considered the possibility of particles as spacetime ...

Could Planck scale wormholes be a solution for non-locality?
When two entangled particles are separated, an observation made on one particle seems to be able to act at a distance to determine the state of the other particle. Is it possible, or has anyone in ...

Have fractional order differential models been explored as an alternative to standard gravitational field theory?
Since Einstein introduced his field equations and general theory of relativity, experimental evidence, at least on the cosmic scale has repeatedly supported the theory. Nevertheless, many seeking to ...

What is space according to quantum mechanics?
We have a pretty good idea what space is in general relativity, yet the strange fact of non-locality in quantum mechanics tells a different story.
Interestingly enough this non-locality doesn't seem ...

What exactly are the high energy problems between general relativity and quantum field theory? [duplicate]
I know there are many questions on physics stack exchange devoted to the question of quantum gravity and reconciling GR and QFT, but don't mark this as a duplicate because my question is a bit more ...

Why Shy away from non-local nature of gravitational energy/momentum? [closed]
Feel free to tear me a new one, This is something that has been bothering me a while.
The very nature of attempting to write gravitational energy/momentum (called the stress energy pseudotensor), ...

Dimension & non - locality problem in string theory
I have some questions with string theory:
Why is it that there is exactly 4 large spacetime dimensions while the rest remain small?
It is a nonlocal QFT. How could that fit in GR?
