Astronomers Find the Earliest Supermassive Black Hole Ever Discovered”

The black hole formed only 690 million years after the Big Bang - aka, when the universe was just 5 percent of its current age, NPR writes.

It has been challenging for the scientists to explain how black holes gobbled up enough matter to reach supermassive sizes early in the history. Astronomers have found a quasar - an active supermassive black hole - that is so distant, and thus so far back in time, that it challenges their models of how these gargantuan objects form.

Simcoe and postdoc Monica L. Turner are the MIT co-authors of a paper detailing the results, published today in the journal Nature.

"This adds to our understanding of our universe at large because we've identified that moment of time when the universe is in the middle of this very rapid transition from neutral to ionized".

Quasars are powered by supermassive black holes in the centers of galaxies - in this case, a black hole with nearly a billion times the mass of the Sun.

But there's a problem with the finding: the black hole appears to be far too big for its age.

But at a time when stars were just starting to light up, they wouldn't have had the time and mass to form such a black hole.

The distance to the quasar was about 13 billion years. "It has an extremely high mass, and yet the universe is so young that this thing shouldn't exist".

Black Friday Sets Gun Background Check Request Record
Analysts note gun sales are likely the higher of the two figures because customers can buy several firearms in one transaction. As reported by USA Today , the number of requests does not necessarily match the number of guns that were purchased.

Before, scientists thought that if there were black holes that formed soon after the Big Bang, there would need to be certain conditions which would allow the supermassive black hole to be born. But based on the size of the Goliath and the age of the universe, it should not exist, said Robert Simcoe, a physics professor at MIT.

It's the first time we are able to detect something this old, and the prospect is exciting as it offers us a unique glimpse into the past.

While the black hole itself remains a mystery, its existence provided the team with another discovery: information about when the stars first turned on, Simcoe said. Roughly 400,000 years after the original explosion, a lot of high energy particles slowed down and cooled down to become neutral hydrogen gas. Eventually, gravity condensed matter into the first stars and galaxies, which in turn produced light in the form of photons. From this, they inferred that stars must have begun turning on during this time, 690 million years after the Big Bang.

Distant quasars are valuable sources of information about the early universe.

The newly-discovered black hole is part of a quasar, meaning it sits at the center of a cloud of gas that it's slowly swallowing. At some point, the radiation released by material as it falls into the black hole carries out so much momentum that it blocks new gas from falling in and disrupts the flow.
