LIGO detected gravitational waves radiating from two black holes that crashed together about 1.3 billion years ago, simulation pictured. Researchers from Kyoto University have suggested the two black holes detected by Ligo could be ‘primordial’ black holes, instead of traditional black holes

An interdisciplinary team of physicists and astronomers at the University of Amsterdam’s GRAPPA Center of Excellence for Gravitation and Astroparticle Physics has devised a new strategy to search for ‘primordial’ black holes produced in the early universe. Such black holes are possibly responsible for the gravitational wave events observed by the Laser Interferometer Gravitational-Wave Observatory LIGO.

The researchers specifically show that the lack of bright X-ray and radio sources at the center of o...

Binary black holes recently discovered by the Ligo-Virgo collaboration could be primordial entities that formed just after the Big Bang. Primordial black hole binaries were discussed extensively in the 1990s. However, interest in them waned when observations implied that their number was limited

New scenario from Japan offers clues about the early universe. Binary black holes recently discovered by the LIGO-Virgo collaboration could be primordial entities that formed just 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.

In February, the LIGO-Virgo collaboration announced the first successful detection of gravitational waves...
