A Big Black Hole Collision Really Shook Spacetime » TwistedSifter

The thing about interesting and good science is that it always leads to more questions than real answers – and when it comes to black holes, our knowledge and desire to know more is always expanding. .

On May 21, 2019, two giant black holes collided 7 billion light-years from Earth.

Spacetime responded by stretching, collapsing, shaking, and producing gravitational waves that rippled through the cosmos.

Scientists here detected the disturbance using LIGO, a two-and-a-half-mile-long pair of identical interferometers in Italy, and they call it the largest, most distant and ‘energetic’ black hole merger. ” all time.

The resulting black hole is about 142 times more massive than the sun.

They published their findings in Physical examination logs and Letters from the Astrophysical Journal.

The signal only lasted a tenth of a second, but the scientists were still excited.

“This is the biggest bang since the Big Bang that mankind has ever observed. This could offer clues as to why the Universe looks the way it does.

This massive black hole is the first “intermediate mass” black hole ever confirmed.

Astrophysicists like KE Saavik Ford of the City University New York Graduate Center think there’s definitely more to be excited about.

“It’s a bridge between the black holes that form directly when stars collapse and the supermassive black holes that are found at the center of galaxies. It takes many, many, many lifetimes in the universe under normal circumstances, so it must have happened in a very dense stellar environment.

LIGO is currently offline, but the facilities will be back online soon, and astronomers like Weinstein hope they can peer further into space — and further into time, too.

“We need to look for more exotic events like this – and more exotic events like we’ve never seen before. Wouldn’t that be awesome? »

I think all science enthusiasts – even those who are much more laid back – can agree that this would definitely be the case.
