As per Imperial College London quantum physicist Terry Rudolph, alien civilizations might change the light coming off stars in order to make contact across far away distances, similar to a series of interstellar smoke signals. Rudolph published his preprint research last week.
The physics of the ordeal gets dense, which makes sense if interstellar civilizations are constantly communicating via star systems. But the main idea is to use entangled photons from several stars to send across messages that appear to be random twinkling at any stargazer.
Alien civilizations in the Milky Way
The scientist notes that this is possible if physics is the concern, but is purely hypothetical when it comes to any debate on alien technology. But he mentions in his research, any entangled communication among stars “can be rendered in principle indiscernible to those of us excluded from the conversation.”
So if there were a more advanced alien civilization in the Milky Way galaxy, communication along the lines of what Rudolph has suggested could shed light on why we haven’t found any signs of extraterrestrial life in the universe.
Rudolph concludes by saying that humans shouldn’t feel bad for not developing an interstellar entanglement communication network. It’s possible that otherworldly civilizations might be capable of exploiting quantum physics.
Should we try to communicate with aliens?
“Entanglement, in our experience, only manifests itself when the cleverest of our species capture and protect it appropriately in controlled and delicate experiments,” Rudolph wrote. “However, once one comprehends how incredibly robust, pervasive, and useful photonic entanglement is the question is flipped — why is it that we did not evolve to make use of it? Why is it that this entanglement did not help us in finding mates or bananas?”
Previously, Michio Kaku, a theoretical physics professor at City College of New York, has warned humans about reaching out to extraterrestrial beings. “I think it’s a terrible idea,” Kaku said.
He believes that we might make contact with the aliens within this century; however, doing so is more terrifying than exciting to the theorist. Kaku said that aliens might be friendly, although they could have nefarious intentions.
