Scientists Found Two Particles That React Faster Than Light

When you measure one of two entangled particles, the other settles into its matching state instantly, across any distance, with nothing traveling between them to carry the message. It's been tested so many times it won the 2022 Nobel Prize, and one team even managed to put a floor on how fast the effect moves. This video walks through the actual experiments, what they measured, and the question they quietly leave open about what "distance" even is.

You'll come away understanding:

what "faster than light" really means here, and why it's not the same thing as faster-than-light communication; why the "it's just like a pair of gloves" explanation is wrong, settled by a single number from John Bell; what the 2015 Delft experiment closed that every test before it couldn't; how a team measured the speed of "spooky action," and why that number is only a floor, not the real speed; and why you can't send a single bit of information with any of it.

If you've ever searched whether quantum entanglement breaks the speed of light, this is the full answer, ending with the part most explainers skip. Tell us what we should break down next using the link below.
