Is the "spooky action" of quantum entanglement truly instantaneous or limited by light speed?

The mathematics of QM predicts instantaneous interaction. Yes, this has been demonstrated experimentally to a reasonable number of significant figures.

As a side note, please ignore crackpots like the person above me.

t = ▲E / light-second

Quantum entanglement is true. Energy bends our perception of distance and time.

Think of it kind of like we're living in a bubble of 1 light-second all around. All of that energy we absorb goes into our perception of life, reality, relativity etc.

As we move along, our bubble always surrounds us. That bubble's range is the impassible "speed of light". We may move along different planes, and jump through slightly different ticking timezones. But our experienced time will typically always be relative to our start point. If we were to shoot in a straight line, faster than the speed of light to a star 5 light years away (relative to an earth observer, warping phenomenon would occur), then back again, the time we experienced in our own bubbles would be very close to the same time everyone else on earth experienced in their bubbles because by reseting your location to earth, your bubble now matches their bubble again - (more or less)

I believe this could be tested x-ray frequency modulation laser transmitter receiver scheme. Circuit modulation tuned for distance kind of like a Tesla power transmitter / receiver.

Also, atomic clocks shot long range, from earth, measure time dilation at peak, then time dilation should counter-act as the atomic clock comes back to earth in the same trajectory that it took off from.
