Black holes are invisible to us. Therefore it has also been tempting to believe that it would be quite a dark show, when two black holes collide a place out in outer space.
How to see it, however, not to be. Rather on the contrary.
U.s. astronomers have just observed a firework display of light, which is a trillion times brighter than the Sun, and which, they believe, can be created by a cosmic collision of two black holes, writes The Guardian according to the Science.dk.
- We are 99,99% sure (that there is a coupling between the light and a collision of the black holes, ed.), says one of the astronomers behind the discovery Saavik Ford, who is a professor at the University of New York, for The Guardian according to the Science.dk.
Saavik Ford have for some time been working on a theory that the collision of black holes could be visible, if the collision took place behind a third black hole's so-called ’opsamlingsskive’, which is the disc of dust and gas that rotate around the hole.
Why have Saavik Ford developed a telescope that was specially designed to spot the sudden light in space.
In may 2019 observed the large international physics and videnskabsprojekt LIGO as a collision of two black holes. The collision was the colloquial name S190521g.
Saavik Ford saw the observation as an opportunity to prove his theory. With his telescope, she gave himself to searching after strong lysudbrud close by and in the same amount of time as S190521g-collision.
And here the researchers found as a match: A bright light that is a billion times brighter than the Sun, to spot on the telescope in the vicinity of the collision.
the Reason why the collision may be seen in the telescope, due to the graviationsbølgerne, who smashes out of the room, when two black holes collide and become one, has pushed to the rotating disk of gas and dust in the third black hole, which creates a 'flame' of light.
Now waiting for other researchers in further analyses that can confirm a correlation between the two observed events.
Saavik Ford's theory that lysudbruddet can be coupled to the collision of the black holes, is published in the scientific journal Physical Review Letters.
