Gravity Seems Holographic. What Does That Mean for Reality?

To me (a total physics layperson with just an interest in it) space and time HAVE to be emergent and not fundamental because of the real phenomena of spooky action at a distance and dual slit craziness. All spacetime surely has to be connected is what it’s telling us.

As far as I understand it,the relative time as we know it, is just something that emerges from the fact that all particle interactions travel with constant light speed.

So if anything moves, the interactions don't change their speed, they stay constant, but the delta to the movement changes, and thus time dilates.

Would be interesting to know if there is some absolute/fundamental global time that has nothing to do with the time we perceive.

Or hear me out here… we as a species have developed measuring methodology that is precise enough at human scale but not actually correct and breaks down at larger scales.

"Spooky action at a distance" only happens in some interpretations of quantum mechanics, and not, for example, in MWI.
