Scientists may have found the first evidence of primordial black holes, born in the very first seconds of the Big Bang. These tiny singularities can be smaller than a single atom but contain almost as much mass as our sun (artist’s impression)
Until now, no one has been able to prove that these bizarre, ancient objects exist.
But by looking for ripples in the fabric of spacetime, known as gravitational waves, researchers think they could have found the ‘smoking gun’ to prove they are real.
On November 12, the Laser Interferometer Gravitational–Wave Observatory (LIGO) and its European counterpart, Virgo, detected an unusual signal from deep space.
The gravitational wave looked like it was coming from colliding black holes, but was much smaller than any known black hole could possibly be.
If it wasn’t a glitch, the only remaining possibility is that the objects producing these faint ripples are the elusive primordial black holes.
Dr Djuna Croon, an astro–particle theorist at Durham University who was not involved in the observation, told Daily Mail: ‘If it’s real, then it’s enormous.’
