Experts uncover chilling theory behind mysterious signal from a parallel universe
The idea of a parallel universe existing is wild to even conceive, yet some experts believe that they've uncovered a chilly theory that could prove its existence, and it's all linked to a mysterious and unexplained sound that was picked up back in 2019.
Some theories from expert physicists have suggested that the Big Bang that started it all is merely a mirror that's hiding another universe currently going 'back' in time at the same rate of our own, but there's still very little to no evidence of this actually existing right now.
It's something that has continued to mystify scientists and astronomers, as the lack of information and evidence we have surrounding the wider reaches of the universe and its history mean that we can't necessarily rule it out.
One mysterious sound that was picked up back in 2019 could provide the key that experts need to investigate the existence of a parallel universe though, and one scientist believes that his chilling theory is what unlocks it all.

As reported by LADbible, the sound in question was picked up by LIGO and Virgo — two gravitational wave detectors that are currently on our planet.
These two apparatus identified an event that was named GW190521, which translated to a sound that existed for nothing more than a tenth of a second in duration, although there remain many questions surrounding its origin.
Many scientists believe that it was transmitted from the moment when two black holes collided, causing a snare that's typically associated with a drawn-out chirp-like sound.
However, a team of scientists led by Dr Qi Lai at the University of Chinese Academy of Scientists believe that this sound is 'proof' of a parallel universe, and it was indeed transmitted through a wormhole that was briefly open.
Dr Lai has suggested that the sound, which wasn't the typical chirp but instead a sharp and brief crack, is the echo of a wormhole collapsing that reverberated the sound of two black holes snaring in a different, parallel universe.
The signal's abrupt cut off is explained by Dr Lai as being linked to the short opening time of a wormhole, and he's firm in believing this contrasting viewpoint of the mystery sound.
"The wormhole represents such an object connecting either two separate universes or two distant regions in a single universe through a throat," he explains.
"The ringdown signal after BBHs (binary black holes) merged in another universe can pass through the throat of a wormhole and be detected in our universe as a short-duration echo pulse."
This would not only offer proof of the existence of wormholes – which remain an alluring mystery for many scientists – but that of a parallel universe too, and both would be equally fascinating and terrifying.
