Are aliens using stars to communicate? According to a pre-print paper published by Imperial College London quantum physicist Terry Rudolph, an advanced civilization could modify the light coming from stars to communicate across enormous distances.

The idea is that aliens may use entangled photons from various stars to send messages that appear to be random blinking to bystanders, and while this is pure speculation, it is technically conceivable in terms of physics.

Rudolph writes that they've shown that free space diffraction of photons distributes highly useful entanglement.
