NASA scientists detect parallel universe next to ours where time runs backwards

preview

An experiment in the frozen wastes of Antarctica revealed evidence of a universe born in the same Big Bang as ours – but with rules of physics that are completely the oppositeVideo UnavailableNASA scientists detected evidence of a parallel universe, right next to ours, where all the rules of physics seem to be operating in reverse. Fans of sci-fi and comic books have known all about parallel universes since the early Sixties. But while physicists have been debating since 1952 whether we actually live in a 'multiverse' – when quantum science pioneer Erwin Schrödinger gave a lecture that he himself admitted might "seem lunatic" – there’s been little evidence so far of dimensions beyond our own. But in 2020 a cosmic ray detection experiment found particles that just could be from outside our universe.Read MoreRelated ArticlesRead MoreRelated Articles’s Antarctic Impulsive Transient Antenna (ANITA) uses a giant balloon to haul delicate electronic antennas high into the cold dry air above Antarctica – where there is little or no radio noise to distort its findings. There is a constant “wind’ of high energy particles coming from – some of which are a million times more powerful than anything we can generate ourselves. Low energy particles – neutrinos – can pass completely through the Earth, barely interacting with the substance of our planet at all. But higher energy objects are stopped by the reassuringly solid matter of the Earth. That means that high energy particles can only be detected coming “down” from outer space. To detect a heavier particle – a tau neutrino – coming “up” out of the Earth would imply that these particles are actually travelling backwards in time. And that is exactly what the ANITA scientists have seen. Peter Gorham, an experimental particle physicist at the University of Hawaii and principal investigator at ANITA, was lead author on a Cornell University paper describing the bizarre phenomenon. Pointing out the sheer impossibility of the tau neutrino’s behaviour, Gorham suggests that the only way it could happen is if the particle changed into a different type of particle before passing through the Earth and then back again. It’s a billion-to-one shot that might just happen once. But the ANITA team have seen several of these “impossible” events. Even as the team wrote their paper they knew the shapeshifting particle idea was a bit of a stretch. “Not everyone was comfortable with the hypothesis,” Gorham told . The simplest – and therefore scientifically the most elegant explanation is this: at the moment of the Big Bang two universes were formed – ours, and another one that from our perspective is running in reverse. Of course if there were any inhabitants of this mirror universe, they’d see ours as the backwards one. While the extraordinary possibility of a twin ‘Benjamin Button’ universe is an exciting prospect, some other researchers say it’s too soon to say for certain that ANITA has received a signal from the anti-universe. Pat Scott, from the University of Queensland, says that while the idea "is plausible” it’s not the only explanation for the phenomenon. He told : There's nothing that necessarily makes it a detection of a parallel universe." Geraint Lewis, an astrophysicist at the University of Sydney., agrees with him. "Whilst parallel universes sound exciting and sexy when discussing the ANITA signal, alternative ideas are still on the table," he says.Read MoreRelated ArticlesRead MoreRelated ArticlesFollow&nbsp;
