Quantum physics contains a theory of entanglement, where two particles originating from a single source – for example, two electrons created from the energy of a collision – are created with a special kind of never-ending connection (communication) between them. Whatever happens to one of the particles instantaneously affects and changes the other (and vice versa).
What is amazing about this connection beyond its timelessness (instantly and forever) is that it is nonlocal, meaning no matter how far apart the particles travel from each other, even if they travel across the universe from each other, the connection never fades. They always mirror each other. They are forever intertwined… separate particles connected as one across space and time.
