A group of scientists have detected gravitational waves due to the largest collision of observed black holes and formed a new black hole about 80 times larger than the sun.
Efe News reported on Tuesday that an international team of scientists led by the US Advanced Laser Interference Gravitational Wave Observatory (LIGO) and Canberra’s Australian National University (ANU) detected this integration with three other black holes.
The Australian National University said in a statement that in July 2017, the fusion of the black hole binary system was detected more than 9 billion light years and led to the largest black hole.
Susan Scott, a physicist at the Australian National University, said: “In all the mergers observed so far, the black hole of this event is also the fastest. It is also the most distant merger currently observed.”
The other three collisions were discovered between August 9 and 27, 2017, between 3 billion and 6 billion light years, resulting in 56 to 66 times more black holes than the sun.
Scott said: “These systems come from four different binary black hole systems that come together to radiate powerful gravitational waves into space.”
The expert emphasizes that observing these collisions will help to better understand how many binary black hole systems exist in the universe, as well as their mass range and the speed at which they rotate during the merger.
The researchers detected the collision after reanalysing the gravitational wave data obtained by LIGO.
The gravitational wave was predicted by Albert Einstein a century ago. It is a time-space vibration that produces some of the most violent events in the universe – like a star’s explosion – that produces a lot of energy.
In the past three years, the team of international scientists has discovered a gravitational wave of ten black holes combined with a neutron star. A neutron star is the densest star in the universe, about 20 kilometers in diameter.
