If advanced extraterrestrial civilizations exist, they could be using stars to secretly communicate with each other in a way that would appear like random blinking lights to others listening in, a new study suggests.
The notion comes from Imperial College London quantum physicist Terry Rudolph, who theorizes 'paranoid' aliens are harnessing the power of entangled photons from various stars to send these hidden messages.
Entangled photons, or quantum entanglement, occur when linked particles of light affect each other no matter how far apart, according to NASA.
This type of communication 'can be rendered in principle indiscernible to those of us excluded from the conversation,' which, according to the pre-print paper published in arXiv, is why we have yet to find life beyond our own planet.

The idea of quantum entanglement is not new, having been dismissed by the
