Nine hundred million years after the Big Bang, in the epoch of our universe's earliest galaxies, there was already a black hole 1 billion times the size of our sun. That black hole sucked in huge quantities of ionized gas, forming a galactic engine — known as a blazar — that blasted a superhot jet of bright matter into space. On Earth, we can still detect the light from that explosion more than 12 billion years later.
Astronomers had previously discovered evidence of primeval supermassive black holes in slightly younger "radio-loud active galactic nuclei," or RL AGNs.
RL AGNs are galaxies with cores that look extra-bright to radio telescopes, which is considered evidence that they contain supermassive black holes. Blazars are a unique type of RL AGN that spit out two narrow jets of "relativistic" (near-light-speed) matter in opposite directions. Those jets emit narrow beams of light at many different wavelengths and have to be pointed right at Earth for us to detect them across such vast distances.
The discovery by Belladitta and her co-authors confirms that blazars existed during an epoch of our universe's history known as "reionization"...
If only one blazar existed in this early phase of the universe, it would be an extraordinarily lucky break for it to have pointed its narrow, visible beam at Earth. It's much more likely that there were many such blazars pointing in all sorts of directions, and that one of them happened to throw its light our way.
These blazars, the authors wrote, were the seeds of the supermassive black holes that dominate the cores of large galaxies across our universe today — including Sagittarius A*, the relatively quiet supermassive black hole at the center of our Milky Way.

Blazar Relativistic Jets ping
The universe “MAY” have been filled with supermassive black holes at the dawn of time.
Then again....
Read the article. Just for kicks and a change from other things dominating the news.
8^)
Frankly, I don’t give a rat’s rear.
Awww.
Thank you for taking the time to post a reply.
Saw something to this effect on ‘How The Universe Works’ on Science channel. Interesting stuff.
Down in the article:
“...previously discovered evidence of primeval supermassive black holes...”
Which is it? MAY or EVIDENCE...
I’ll wait for “Ancient Aliens” on History, to tell me the “truth”. LOL.
Also they had Treadmill: The mighty Lager with the world’s first great taste of fish.
You’re catching a little heat here, LOL!
Bookmarked for later read, looks interesting.
Exactly!
Happy to take the heat. At least it’s letting FReepers vent without ripping into each other over the WuFlu.
Blazars are a unique type of RL AGN that spit out two narrow jets of “relativistic” (near-light-speed) matter in opposite directions.
Well, if it spit them out in only one direction it would
push them up to relativistic speeds and who knows what
would happen then.
Good article, though; thanks for posting it. I wish I understood half of it. Heh.
I saw the title and that’s the first thing I thought.
Good diversion.
So black holes existed at the dawn of time, but it can’t be the dawn of time because if this article is accurate then how were the black holes formed and when....
It’s one of those questions than can’t ever be answered, because it would imply that at one time nothing existed and then things began to form....
You’re all racists. Why does the color black get all the bad stuff? Why aren’t they called white holes or yellow holes or something?
Then again, maybe not.
