Scientists detect biggest ever black hole collision
New Delhi : In a new development, scientists have detected huge collision between two black holes in a distant galaxy. The gravitational waves from the collision are leading to the formation of a new, huge black hole 80 times larger than our sun.
Experts mention that it is their fourth number detections in this week, using data from the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) which detects gravity waves, tiny ripples in space and time.
Professor Susan Scott of Australian National University (ANU) said that the event occurred nine billion light years away. The ripples were observed from the merger on 29 July 2017.
The ripples were detected from the merger on 29 July 2017.
‘This event also had black holes spinning the fastest of all mergers observed so far. It is also by far the most distant merger observed,’ Professor Scott said.
Record says that three black-hole collisions were detected between 9 and 23 August 2017, were between three and six billion light-years away and ranged in size for the resulting black holes from 56 to 66 times larger than our Sun.
‘These were from four different binary black hole systems smashing together and radiating strong gravitational waves out into space,’ said Professor Scott.
‘These detections of black-hole collisions greatly improve our understanding of how many binary black hole systems there are in the universe, as well as the range of their masses and how fast the black holes spin during a merger.’
As of now, researchers are planning to continuously improve the gravitational wave detectors so they can detect cataclysmic events much further out in space, with the hope to reach back to the beginning of time just after the big event.
