Earlier this year, gravitational waves were found in what was called the 'discovery of the century'.
The Laser Interferometer Gravitational-Wave Observatory (Ligo) detected gravitational waves radiating from two black holes that crashed together about 1.3 billion years ago.
Now evidence is building that these black holes might be 'primordial' black holes, instead of traditional black holes.
If they are, they could be the answer to what makes up the mysterious dark matter, an unidentified substance that makes up 85 per cent of the mass of the universe, some researchers have said.
Researchers from Kyoto University have published a study in the journal Physical Review Letters today, suggesting the two black holes detected by Ligo could be 'primordial' black holes, instead of traditional black holes.
This means instead of being created when stars collapse at the end of their lives like most black holes, these might have formed from the extreme density of matter present soon after the big bang.
If further data support this observation, it could mark the first confirmed finding of a primordial black hole, guiding theories about the beginnings of the universe.Read more: http://www.dailymail.co.uk/sciencetech/article-3712650/Have-new-kind-black-hole-Gravitational-waves-come-primordial-objects-old-universe.html#ixzz4G0pA2oMs
