Yea I read about this.
Quantum entanglement is still such a sci-fi concept that it's hard to almost accept that it's real.
I mean, doesn't completely destroy Einsteins relativity theory? There must be some form of communication between the particles that are faster than the speed of light yes?
Spooky to the max.
It is nothing new. I studied it on college.
It is not that crazy, really.
A very brief explanation. You have two entangled electrons, you don't know their spin.
If you measure one of their spins and it is +1/2, the other is automatically -1/2 when you measure it. I don't know how to explain but scientists proved the spin is not determined before you measure it.
So if you have two entangled electrons, one here and another in another galaxy, you can by measuring an electron here, cause the electron in another galaxy to be the opposite spin. Automatically, so yeah you caused an effect faster than light.
But it is random, and there is no way to send a message.
If you could CHOOSE the spin here you could create a system of communication, like every positive spin(negative on the other side) represents 1 or 0 in binary. But you can't.
Veritasium on youtube did a much better explanation of course.
