A new study has found that two supermassive black holes will merge within 10,000 years, in a collision that will cause ripples across the universe.
The study, led by a team of astronomers at the California Institute of Technology, found that two supermassive black holes, about 9 billion light-years away in deep space, orbit each other every two years.
Each supermassive black hole has a mass hundreds of millions of times greater than the mass of our sun.
In addition, the two objects are relatively close to a distance of 1950 astronomical units (about 50 times more than the distance between our sun and Pluto)
The two bodies will collide 10,000 years from now, in a collision so intense it will send gravitational waves through the fabric of space and time.

The authors say that despite the fact that galaxy mergers are not rare, “there have been relatively few instances of two galaxies with supermassive black holes (SMBHs) in their cores seen in the actual merger.”
The researchers discovered the two objects in a high-energy body known as a quasar, a highly energetic, highly luminescent galactic core powered by a supermassive black hole.
according to California Institute of TechnologySome supermassive black holes of quasars blast jets at the speed of light — in the new study, the quasar, designated PKS 2131-021, belongs to a subclass of quasars called blazars, which fire their jets at Earth.
The researchers hypothesize that PKS 2131-021, observed more than 45 years ago, is now the second known quasar with a pair of supermassive black holes about to merge.
The first known quasar is called OJ 287 and has two black holes that separate from each other and orbit each other every nine years.
So how do two supermassive black holes converge?
When galaxies clump together, their black holes are normally drawn toward the center of the newly accreted galaxy, eventually forming a larger black hole.
And as black holes merge, their immense power tears the fabric of the universe apart with gravitational waves.
