Astronomers Discover 83 Supermassive Black Holes at the Edge of the Universe (cnet.com)
"A team of international astronomers have been hunting for ancient, supermassive black holes -- and they've hit the motherlode, discovering 83 previously unknown quasars," reports CNET:
The Japanese team turned the ultra-powerful "Hyper Suprime-Cam", mounted to the Subaru Telescope in Hawaii, toward the cosmos' darkest corners, surveying the sky over a period of five years. By studying the snapshots, they've been able to pick potential quasar candidates out of the dark. Notably, their method of probing populations of supermassive black holes that are similar in size to the ones we see in today's universe, has given us a window into their origins.
After identifying 83 potential candidates, the team used a suite of international telescopes to confirm their findings. The quasars they've plucked out are from the very early universe, about 13 billion light years away. Practically, that means the researchers are looking into the past, at objects form less than a billion years after the Big Bang. "It is remarkable that such massive dense objects were able to form so soon after the Big Bang," said Michael Strauss, who co-authored the paper, in a press release. Scientists aren't sure how black holes formed in the early universe, so being able to detect them this far back in time provides new avenues of exploration.

I think they mean, edge of the observable universe.
I have discovered several hundred large holes punched at the edge of my boots. They seem to be seaming the uppers and lowers. It is unclear how such holes might have appeared.
It's always the way, innit? You hang around for three million years in deep space and there hasn't been one, then all of a sudden eighty three turn up at once.

Whew! What a way to start the work week! This portends smooth sailing ahead!
Ah the old brilliant line of "I'm dumb, therefore no-one else can know anything".
Could it be that we have neighbours?
Could our universe be a part of a cluster of spheres that implode/explode periodically?
If these (and millions more) are hard to see, and have large amounts of gravity, could it be that they're what's causing the universe to expand quicker than expected?
Doctors often engage in "I went to school, therefore no one else can know anything".
BTW what's with that hyphen??
Godel was smarter than Einstein and much better at math. It's a closed loop of time-like space. The sun comes up, the sun goes down, we perceive the loop as time passing.
"Scientists aren't sure how black holes formed in the early universe, so being able to detect them this far back in time provides new avenues of exploration."
A nice departure from the hyperbolic "Scientists are shocked to find...." or "Scientists scramble to find answers when the laws of physics are turned on their head!" sort of wording.
The shepherds did so well protecting the flock that the sheep no longer believed that wolves existed.
This sounds like more fake science pushed by fake scientists with an agenda. There is still no convincing evidence that the big bang ever happened or that the world is older than about 4000 years.
Light scatters in all directions (for the most part) from the origin of a single point of event.
No, a photon will travel in a straight line from it's point of origin unless acted upon by an outside force. You are describing what happens to the innumerable photons that are emitted from a typical light source which is not the same thing. The photons that we see from these distant sources have traveled a long distance in a straight line (*) to get to us.
(* straight in this context is not the same Euclidean geometry straight line you might have learned about in high school)
So if it happened 13 billions year ago, how is it still observable?
Because the universe expanded faster than the speed of light. Space itself is expanding to this day and so some light that was emitted a long time ago is just now reaching us. Some light that was emitted a long time ago will never reach us because it's too far away and space is expanding too fast for it to ever get to us.
These are not mutually exclusive ideas, and your point is irrelevant.
The hypen is correct in British English, which is my native language. It also disambiguates between a singular entity (e.g. "There are four men in a room. No one can lift the boulder.") a mass ("No-one knows how many piano tuners there are in Europe.")
There was the arms race in that corner of the universe creating supermassive blackholes. One team was going one up over the other. And when the score was 41-42, one team got the ultimate answer. So they won and the tournament ended. That's how they ended up with 83.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
In 2D flatland, if something was in front of you, and then behind you, it would have to go above or below you. If it never went above or below you, then you would notice the violation of 2D spacial rules, and deduce the higher dimension. There are no galaxies spinning in higher than 3D, no flywheels disappearing in space, so there is no higher dimension because we don't see any violations of the 3 dimensions.
We are not special and our universe is not creating space. That's the sort of logic that put the earth at the center of the solar system! Here you've put our universe as a special one time event, that creates space as it goes along.
Photons are not special, and do not have a special time context to themselves.
They move across the resonant field, 0W, 1W, 2W, 3W..... at a speed of 1W per spin, chasing the next resonance point 1W along.
When wrapped around a -ve monopole, as a 2 resonant wavelength F2 donut, they oscillate 0W, 1W, 0W, 1W, 0W.... an oscillation at the left of the donut, is at the right on the next oscillation, and back on the left after that, right, left.
The energy in a photon and the energy of momentum in mass is the same, it's the difference between the velocity and the resonance point. The further from resonance, the higher the energy. So we require energy to move away from zero resonant point, (0W per oscillation), and light requires energy to move away from 1W per oscillation resonant point. Both are chasing resonance.
Lights wavelength is the difference between it's near 1F oscillation and the near 1F oscillation of any matter it hits.
Big bang was a theory deduced from the expanding universe.
Then it was fixed up with an unexplained 'inflation'
Then it was fixed up again, by creating 3D space in a 5D bubble, where we can only perceive the outer shell as 3D.... somehow.... but that would be impossible because of flatlands logic.
It's time to let go of big bang.
It's time to let go of a lot of this garbage.
From the photon point of view, there is no time, all path are instantaneous, short (human size) or astronomical (accross the observable universe), for the photon it ages exactly a perfectly zero seconds.
I accept this as apparently factual. What I'm having trouble wrapping my brain around is the relationship between the statement above and how photons travel through spacetime if they do not experience time. Speed = distance / time and photons have the constant speed = c. But if time for them = 0 then that fundamental mathematical relationship breaks down and is undefined. (cannot divide by zero but we are essentially saying c=dist/0) My confusion is, how does a photon travel a distance through spacetime non-instantly (which it clearly does) if it does not experience time? Photons travel at a fixed rate through spacetime which is demonstrably not infinite and has time in the definition of that rate.
I expect the answer to be some non-intuitive reference frame of the observer sort of answer or something about velocities in spacetime (as opposed to space) being constant but I can't seem to puzzle it out.
For this reason, God sends them a powerful delusion(operation of wandering)(planet) so that they will believe the lie.

If the further back in time you go, you lots more black holes and they're larger, then black holes are shrinking as time progresses.
So galaxies don't contain black holes sucking them in, they contain black holes ejecting them as they shrink and spin.
So older stars should be further out of spiral galaxies, and newer stars further in to the center, because they were ejected last.
And if a blackhole can eject matter, and we are being ejected outwards, then we are in such a black hole.
What is the challenge in understanding early blackhole formation?
If energy coalesced into enough matter that was close enough to other matter, wouldn't that be enough g to create a mass that collapses on itself?
Shouldn't need a supernova to do that, right?
And one restaurant.

You are welcome on my lawn.
Thats SOOOOO useful guys! Good thing none of that hookers & coke money for truly useless science went to feed, clothe, and house your fellow human beings.
Fuck those guys.. hookers & blow & blackholes gais!!!
Xeelee Nests.
A photon as a particle will travel in a straight line as you classically think, however it is also a wave and has uncertainty according to Heisenberg uncertainty.
This is true but not relevant to this particular discussion. A photon from Betelgeuse does not diffuse to both Alpha Centauri and our Sun in any practical sense. It's not a useful exercise to treat the uncertainty in the position of a photon in units of light years. Remember we are talking about photons we've actually observed through our eyes or through out measuring equipment.
If you constrain the photons position, say by emitting it from a point and passing it through an arbitrarily small orifice, cementing position, momentum blows up and spreads it out.
It doesn't spread out to distances measured in light years. And we are constraining the photon's position because we have observed it.
does it take to hold up the universe? 83.
