Quantum entanglement allows particles to instantaneously interact.

Quantum entanglement is a fascinating phenomenon in physics where two particles become interconnected in such a way that the state of one particle directly affects the state of the other, regardless of the distance between them. This means that changes to one particle will be instantly reflected in the other, even if they are light-years apart. This mysterious connection, described by Albert Einstein as "spooky action at a distance," has been the subject of intense study and has profound implications for our understanding of the fundamental nature of reality at the quantum level.
