China launches quantum satellite to test spooky action at a distance

‘China has launched a satellite dubbed “Micius” that bears the Quantum Experiments at Space Scale (QUESS) instrument it will use to test quantum communications between Earth and space.
QUESS’ key payload is entangled photons. A quick primer: if you fire a photon at a certain crystals it will split into two photons. Both of those photons will have exactly the same qualities. Almost miraculously, any change to the first photon will be mirrored in the second. Just how that change propagates across space and time is not understood. It’s also thought that whatever it is that lets entangled photons share information may take place faster than the speed of light.’
