Spooky action at a distance is an enigmatic term coined by Einstein meant to describe quantum entanglement, or the strange phenomenon when particles, or objects– potentially of any size and at any distance apart, become inexplicably linked together. These bonded entities become responsive to one another as if invisibly tethered in ways scientists do not really understand, and which can no longer be described as independent. The theory is so unusual that Einstein was essentially dismissive of the possibility even while reflecting on it, but the concept has since been documented and confirmed.
