With so many dramatic events happening down here on our beloved Earth these days, let’s take a deep look at the skies for a change.
It’s been revealed that gravitation-wave astronomers have detected a collision between two black holes of different masses that opened up a new view on astrophysics and the physics of gravity.
Shocking black hole evidence
The space-time ripples are offering the first unmistakable evidence from the technique that at least one black hole was spinning before merging.
This offers astronomers important info about one of the few features that they can study in the dark objects.
Maya Fishbach, an astrophysicist at the University of Chicago in Illinois said that this is an exceptional event.
It’s also worth mentioning that similar mergers on which info was published all took place between black holes that had similar masses, and this new one is dramatically upsetting that previous patterns, she said.
This collision was detected back in 2019 and it has been revealed a few days ago on April 18.
Nature.com writes that the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo observatory in Italy both spotted the event, identified as GW190412, on 12 April 2019.
The LIGO-Virgo collaboration also includes Fishbach, and posted its findings on the arXiv preprint server.
More findings will be published
LIGO made its every first discovery of gravitational waves back in 2015 and found space-time ripples from two emerging black holes. After Virgo joined LIGO, ten more detections were made: one collision of two neutron stars and nine more black hole mergers.
It’s important to mention the fact that the LIGO-Virgo collab will continue to publish more findings from their unpublished data. This includes individual events that are exciting and interesting at the same time.
The harvest seems to be quite good, according to the opinion of physicists at the National Insitute for Subatomic Physics in Amsterdam.
Not too long ago, it’s been revealed that for decades now, experts have suspected that some of the light that’s escaping from around enormous black holes almost does not make it and now they have finally seen this happening.
