Astronomers at Columbia University presented evidence that a pair black holes is creating rhythmic flashes of light that are originating from quasar PG 1302-102. They said these black holes are on the course of collision which will be so powerful that it would send bursts of gravitational waves through wide range of space.

The calculations of the mass of the black hole pair together and n relation to each other, astronomers said the collision of the black holes will take place almost 1,000 years from now.

Study’s lead author Daniel D’Orazio said, “The detection of gravitational waves lets us probe the secrets of gravity and test Einstein’s theory in the most extreme environment in our universe–black holes. Getting there is a holy grail of our field”.

Daniel, a graduate student at Columbia, said both the black holes are presently rotating 3.5 billion light-years away, inside the Virgo constellation. The two black holes are just a light-week away from each other, said experts.

Senior author Zoltan Haiman, astronaut at Columbia, said in a statement that this is the so far the closest they have seen two black holes that are on way to a massive collision.

Haiman said watching their collision can help them know whether black holes and galaxies grow at the same rate. They can also test a fundamental property of space-time i.e. its ability to carry vibrations called gravitational waves, produced in the last, most violent, stage of the merger.
