Long-term radio observations of a supermassive black hole in the center of the galaxy seem to show that it has an unseen colossal companion. Caltech-led observations made over 13 years by the Owens Valley Radio Observatory in Northern California reveal that the radio black hole will soon merge with an associated black hole to form a supermassive black hole binary (SMBHB). These two supermassive black holes appear to orbit each other every two years, Caltech reports. Each of the two giant objects has masses hundreds of millions of times greater than the mass of our sun, and the objects are separated by a distance of about 50 times greater than that between our star and Pluto, notes the Caltech, but when the pairs merge within 10,000 years, a giant collision is expected to shake the place and time itself, sending gravitational waves across the universe. The observations are detailed in a paper that appeared in the astrophysical journal Letters. The observed quasar, PKS 2131-021, is part of a subclass of quasars called blazars in which the jet is pointed toward Earth. Currently, it is only the second known candidate for a pair of supermassive black holes discovered during the merger process. said Joseph Lazio, an astrophysicist at NASA’s Jet Propulsion Laboratory and one of the authors of the article cited by Forbes.

After two supermassive black holes join in a mythical cosmic waltz 9 billion light-years away, they appear to orbit each other every two years.
Long-term radio observations of a supermassive black hole at the center of a galaxy seem to show that it has an unseen supermassive companion.
Caltech-led observations were made over a 13-year period by the Owens Valley Radio Observatory in Northern California and revealed that the radio black hole It will soon merge with an accompanying black hole to form a supermassive binary black hole (SMBHB).
These two supermassive black holes appear to orbit each other every two years, according to a Caltech report. Each of the two giant bodies has masses hundreds of millions of times greater than the mass of our Sun, and the bodies are separated by a distance of approx. 50 times greater than the distance between our star and PlutoBut when the pair merge in about 10,000 years, the giant collision is expected to shake space and time itself, sending gravitational waves across the universe.
Can a black hole turn into a white hole?
The notes are detailed in a paper published in The Astrophysical Journal Letters.
Observed quasar PKS 2131-021, is part of a subclass of quasars called blazars in which the plane is directed toward Earth. Currently, it is only the second known candidate for a pair of supermassive black holes discovered during the merger process.
“From an astrophysical perspective, we would expect supermassive black hole binaries to exist,”
He said Joseph Lazio, an astrophysicist at NASA’s Jet Propulsion Laboratory and one of the co-authors of the paper cited by Forbes.
“Most, if not all, large galaxies have supermassive black holes at their centers, and it has been observed that galaxies undergo merging processes, so there must be supermassive black hole binaries as a result.”
