Black hole collision has just demonstrated Albert Einstein's correctness

Einstein's prediction has been confirmed by a massive black hole collision that exhibits extreme evidence of wobbling.

 

A gravitational phenomenon predicted by Albert Einstein a century ago has been proven by two black holes swaying three times per second when they fused. Precession is a phenomenon that resembles the swaying motion that results from the merger of two massive black holes from the past. General relativity's prediction about how gravity alters space-time fabric leads to the phenomenon known as gravity-induced orbital precession or wobbling.

 

During the very early stages of a neutron stars orbiting one another, this phenomenon had been seen. Mark Hannam from Cardiff University in the UK and his colleagues claim to have observed a massive effect in a pair of black holes, where one of them is spinning at a fifth of the speed of light at a 90-degree angle to its orbital motion. Their findings were published in Nature magazine. And as the two black holes collided, GW200129, a gravitational wave with the signature of a three times per second precession, was released.

 

Hannam explained the phenomenon in the same way, stating that "it's 10 billion times quicker than what was found in earlier observations, so it's the most extreme regime of Einstein's theory where space and time are stretched and distorted in utterly crazy ways."

 

Hannam's team reanalyzed data from three gravitational wave detectors located in the US, Italy, and Japan that were collected in 2020 to find this wobbling object. While earlier analyses found no evidence of precession, Hannam and his team now believe that the signal came from one of the black holes, which was spinning at nearly the maximum rate permitted by general relativity.

It is "a region of space where gravity is so intense that even light can't escape," according to Regina Caputo, a research astrophysicist at NASA Goddard Space Flight Center. According to NASA, the reason why gravity is so powerful is that dying stars compress stuff into a small area.

 

Black holes are invisible because light cannot escape from them. Space telescopes equipped with specialised equipment can be used to see black holes as well as how stars near them behave differently from other stars.
