Researchers from NASA are seemingly worried as two super massive black holes are about to collide with one another.
According to the findings from a new study, astrophysicists from Columbia University discovered that a pair of closely orbiting humongous black holes in the Virgo Constellation are a lot closer than initially thought – only one light-week apart. If and when the collision occurs, an indescribable burst of gravitational waves is expected to surge through the entire architecture of space and time itself.
According to the calculations by the researchers, the pair of gigantic black holes are approximately 3.5 billion light years away from Earth.
“This is the closest we’ve come to observing two black holes on their way to a massive collision. Watching this process reach its culmination can tell us whether black holes and galaxies grow at the same rate, and ultimately test a fundamental property of spacetime: its ability to carry vibrations called gravitational waves, produced in the last, most violent, stage of the merger,” commented astronomer and the study’s senior author, Zoltán Haiman, in a Columbia press release.
The pair of black holes were first discovered last winter, by a team at the California Institute of Technology in Pasedena via the flickering lights called quasars that black holes normally produce as they constantly burn through the gas and dust surrounding them. Usually quasars flicker in a very sporadic fashion; however the flickering lights from these two black holes were far more frequent and were brighter as well. The quasars were named PG -1302-102 and scientists believe as the collision date comes closer, the lights will keep getting brighter, just like how a siren gets louder as it approaches closer.
Researchers from the University of Columbia tried to create a model to explain the repeating quasars. According to their research, the light from the quasar was coming from a disc of gas surrounding the smaller of the two black holes.
“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,” said Daniel D’Orazio, a graduate student at Columbia and the study’s lead author.
