A colossal collision between supermassive black holes would shake the Universe in 2025

The strange behavior of a galaxy located about a billion light years away from Earth suggests that it could host one of the most anticipated events by contemporary astronomers: the collision between two supermassive black holes. Although it is not yet possible to determine with certainty the exact moment of the violent encounter, scientists believe that it could take place in around 3 years.

A group of researchers concludes in a new study that the variations in light observed in the center of the galaxy SDSS J1430+2303located approximately one billion light-years away from our planet, coincide with what is expected for the previous moments of a collision between supermassive black holes, which in this case would reach a combined mass of around 200 million suns.

According to the new research, recently published in ArXiv and accepted for publication in Astronomy & Astrophysics, the crash is really imminent and not in astronomical terms, in which time periods beyond human understanding are handled. In this case, if the identified signal is really the result of colossal supermassive black holes, they will merge in the next three years, that is, at the latest around 2025.

A galaxy in turmoil

SDSS J1430+2303 is known to be a elliptical galaxy with a cumulative mass of 150 billion suns. It presents an active galactic nucleus, which is undergoing periodic variability in permanent acceleration. Because of this, some specialists believe that the binary black hole near the melting point could dock and release an impressive amount of energy. even before the end of 2022.

It would be a fantastic opportunity, perhaps the best so far, to appreciate the clash of two supermassive black holes. However, the researchers cannot yet determine with certainty whether the phenomenon that is happening in the heart of the analyzed galaxy is really the scenario prior to a collision of this type. The scientists indicated that it is essential to continue observing the strange galaxy, to see if the event can be conclusively identified.

Previous data indicates that the first detection of colliding black holes took place in 2015: from there, a new challenge for astronomy was born. Since then, more detections have been made, thanks to gravitational waves that these massive events send through space-time: they are huge fluctuations that can be detected by the most advanced instruments, such as the laser interferometers located at the LIGO and Virgo observatories.

almost confirmed

Apparently, the variations in the X-ray light emitted by the galaxy SDSS J1430+2303, as well as a type of emission associated with iron, would be indicating with a confidence level of 99.96%based on two different instruments, that the phenomenon would be an imminent collision between supermassive black holes, according to a Article published in Science Alert. Despite this, scientists are cautious and await other data that will fully confirm the indicated phenomenon.

The collisions between supermassive black holes are crucial for obtaining information that allows scientists to understand How do black holes get so big?as well as to determine the role of these incredible events in the formation of new cosmic structures, among other astronomical phenomena that do not yet have definitive answers.
