Boffins reckon they have received a signal from a parallel universe. ‌

In 2019 gravitational wave detectors on Earth picked up a ripple from deep space that left scientists baffled. ‌

Now they reckon the strange ripple - dubbed GW190521 - could have arrived from a parallel universe via a wormhole.

A team led by Dr Qi Lai, of the University of Chinese Academy of Sciences, believes it could be an ‘echo’
