Two giant black holes could collide in 3 years

Two giant black holes could collide in 3 years

Such an event does not happen every year: data from the galaxy SDSS J1430+2303 suggests that it may happen 2 supermassive black holes You will bump into their center. But there are still some doubts.

The two black holes, which are about a billion light-years away, have the same weight 200 million suns. According to the researchers, there may be a collision in the future 3 years to speak. Until then, one must continue to observe the galaxy.

Scales not designed for collision

The first collision between two black holes was discovered in 2015, and since then the collision of black holes with one has been observed simple star block Limited. No wonder, because Gravitational wave detectors LIGO and Viro, who can detect such events, target these crowds.

But supermassive black holes can do that A million to a billion times the mass of our Sun Reach. The gravitational waveswhich arise on collision, have a very low level repeatthan can be identified by the detectors in use today.

Supermassive black holes puzzle

But the researchers expect that the collision will also be noticeable with the help of gravitational wave detectors. In the event of a collision, all kinds radiation is released. They can be recorded on the ground and provide insight into how huge black holes exist at all. So far it is still not clear why it can become so heavy.

SDSS J1430+2303 hub has been observed for years and always frequent vibrations registered from it. This data allows 2 very heavy celestial bodies Close, which surround each other. Whereas 3 years ago they were still in year In a circle, they now only need one orbit one month.

The data is difficult to interpret

However, it is not clear whether these black holes are supermassive, because the data from Galactic centers difficult to explain. X-ray measurements Underline the researchers’ thesis, but there is no such thing as 100% certainty.

However, J1430+2303 is almost certainly happening in the middle of SDSS, which we haven’t seen before. The coming years will provide more details.
