Scientists found a black hole 12 billion times more massive than our Sun

Astronomers have detected an ancient black hole that’s so incredibly
massive and luminous, it defies our understanding of the early
Universe. It’s so big, we need new physics to explain it.

In fact its quasar, the shining object produced by a supermassive black
hole, is 420 trillion times more luminous than our Sun – despite forming
only around 900 million years after the birth of the Universe. This
makes it the brightest object ever spotted in the ancient Universe. It’s
so impossibly bright that it’s almost, well impossible.

“How could we have this massive black hole when the universe was so
young? We don’t currently have a satisfactory theory to explain it,” the
lead researcher, Xue-Bing Wu, from Peking University in China and the
Kavli Institute of Astronomy and Astrophysics in the US, told Rachel Feltman from The Washington Post.

The
quasar, known as SDSS JO100+2802, is located around 12.8 billion light
years away from Earth, and was spotted by the Sloan Digital Sky Survey,
before being verified by three Earth-bound telescopes.
Reporting in Nature,
the team explains that for the black hole to reach such a massive size
in less than a billion years, it would have been constantly sucking in
interstellar mass at its maximum rate. But this doesn’t fit with our
current understanding of black hole growth, which states that the
process is limited by energy that blasts out of the quasar as the black
hole heats up.
Following that hypothesis, and also factoring in
the limited amount of matter available in the early Universe, it makes
it extremely difficult for scientists to explain how the supermassive
black hole exists – and how it came to be 12 billion times more massive
than our Sun.

“With this supermassive black hole, very early in
the Universe, that theory cannot work,” Fuyan Bian from the Australian
National University, who was involved in the research, told Genelle Weule and Stuart Gary for ABC Science. “It’s time for a new hypothesis and for some new physics.”
But
even though we’re still not sure how the mega quasar is possible, it’s
going to be a useful tool for finding other objects in the Universe. 
“This
quasar is very unique. Just like the brightest lighthouse in the
distant universe, its glowing light will help us probe more about the
early Universe,” said Wu in a press release.
