Aliens are trying to contact us, but their efforts are a colossal waste of time and space, scientists fear.
They say that aliens can send us messages in particles of light – and the dangerous interstellar journey turns them into cosmic traps.
A new report says intelligent aliens are most likely using “quantum communications” to send messages thousands of light-years away.
Messages are transmitted via tiny subatomic particles – so delicate that they could be destroyed if they reach us.
Scientists say that not only would they have trouble understanding messages about aliens, they wouldn’t even know if they even came from them.
The “quantum gibberish” theory could also be true the other way around – crushing hopes that ET will ever phone home.
Prof Arjun Berera, theoretical physicist at the University of Edinburgh, said: “In principle it should be possible to detect a quantum signal from an astrophysical body or even an intelligent signal from an extraterrestrial civilization.”
But he added: “Quantum states that you think are very delicate, and if there’s any kind of external interaction, destroy that state.”
However, there was some hope that all the little green men out there would eventually become less misunderstood.
The report, published in Physical Review, says new technology is being developed to allow scientists to search for quantum messages.
ET fanatic Spencer Yardley, 45, of St Albans, Herts said: “I am very certain that I will encounter an extraterrestrial life form during my time on Earth.
“I just hope they’re friendly and don’t come at us with lasers.”
