Einstein-Podolsky-Rosen Paradox ?
EPR Paradox was essentially a thought experiment counterintuitive during that time. It argued that the reality around us described by quantum mechanics is incomplete. The idea of spooky action at a distance is a part of this paradox. According to it, if two particles are formed at the same time, they are in a quantum-entangled state, which means that if we measure the spin of one of the entangled particles, then we can accurately predict the spin of the other entangled particle (placed even light years away!!) as it's spin is just opposite to the first particle this is popularly referred as spooky action at a distance. But this mysterious communication channel was always a topic of debate as it challenged Einstein's relativity, as the speed of communication is greater than the speed of light. The Nobel prize in physics for 2022 dives into the spooky action and attempts to explain most of it. I will attach links at the end to resources related to this year's Nobel prize in
