back then! Some Chinese scientists have measured the speed of quantum
entanglements, and it's at least 10,000 times faster than lightspeed!

Please look up "Aspect experiment," and then tell us what exactly is
new. (I'm not saying "nothing," but I doubt it's the basic concept.)

Unless there's something truly extraordinary here, the "spooky
action" doesn't allow sending information faster than light.

We probably won't know that until we actually test Bell's Theorem out in
real life, and not just in thought experiments.

I'm not sure what you mean, because aren't the experiments that established that quantum entanglement really exists, or this particular Chinese experiment, tests of Bell's Theorem? Some of the early experiments involved things like randomly changing the orientation of the polarizers too quickly for the information to travel to the other polarizer in order to exclude weird non-FTL possibilities.

You didn't actually look up "Aspect experiment," did you?
