Quantum entanglement. Quantum mechanics

In 1982, Alain Aspect sent two simultaneously created photons to opposite-direction spin (polarization) detectors. It turned out that measuring the spin of one photon instantly affects that of the other photon, which will be the opposite. This proved the possibility of the quantum entanglement of elementary particles and quantum teleportation. In 2008, scientists were able to measure the state of quantum-entangled photons at a distance of about 90 miles, and interaction between them was still instantaneous, as if they were at the same place or there was no distance.

It is believed that if such quantum-entangled photons appear at opposite ends of the Universe, then interaction between them will still be instantaneous, even though it would take tens of billions of years to cover that distance at the speed of light.
