Jakarta, CNBC Indonesia – Two giant black holes are said to be colliding with each other. If that happened it would shake the fabric of space-time.
The findings are in a study published in The Astrophysical Journal Letters. The black hole, which shares the name PKS 2131-021, is 9 billion light-years from Earth.
The two objects reportedly continued to move toward each other for about 100 million years, NASA said. Now both share a binary orbit and the black holes orbit each other every two years or so, quoted from Live Science, Friday (4/3/2022).
Researchers say 10,000 years from now the two will merge and send gravitational waves soaring across the universe. This is a ripple in the fabric of space-time that Albert Einstein originally predicted.
PKS 2131-021 is a special type of black hole known as a blazar. Namely a large black hole that happened to direct a beam of supercharged matter directly at Earth.
The material is from a ring of hot gas that forms around a particular black hole. As the black hole attracts the gas with its strong gravity, some matter may escape and be pushed away in a jet of plasma that travels at the speed of light.
The study’s authors monitored the brightness of about 1,800 blazars across the universe. Then found something strange, the brightness of the blazar PKS 2131-021 fluctuates periodically.
The change, they say, is the result of the second black hole attracting the first object, as both orbit each other. But according to the research team, more data is needed to see how long the patterns last.
In the end, they dug up data from five observatories in the last 45 years. All of the data matched the team’s predictions of how the brightness of the binary blazars matched the team’s predictions of how the brightness of the binary blazars changed over time.
