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.

Moochelle?
There was no universe until the beginning of time.

Oy, sounds like hell.
Black holes, by definition, do not let matter or radiation escape. Radiation from the vicinity of a black hole can happen as matter waiting to fall in crashes into itself and creates radiation. But, at a certain distance, even very energetic radiation itself is trapped. Bonus question: if the big bang began with all the matter in the universe concentrated into one small space, how did any of that matter escape from what would be the mother of all black holes?
The next doomsday threat we are facing?
And the moon is made of green cheese. All speculation. Want the truth? Read the first eleven chapters of the Book of Genesis in the Bible. Don’t have a Bible? I’ll gladly give you one for free.
You do know that there is a lot information about the composition of the moon, yes?
There’s a lot of information about green cheese, too.
