One of Stephen Hawking's most famous theories about dark matter — that this mysterious and invisible substance is made up of primordial black holes — recently suffered a huge blow. That conclusion comes from a massive telescope that captured an image of an entire galaxy in one shot.
The findings don't completely rule out Stephen Hawking's famous notion. But they suggest that primordial black holes would have to be truly tiny to explain dark matter. Dark matter mystery
Dark matter is the name given by physicists to explain a particularly mysterious phenomenon: Everything in the universe moves, orbits and rotates as if there were more mass than we can detect. Explanations for dark matter range from ghostly particles called neutrinos to unknown particles, to new laws of physics. In the 1970s, Stephen Hawking and his colleagues theorized that the Big Bang may have created a large number of relatively small black holes — each about the size of a proton. These tiny, ancient black holes would be difficult to see, yet would exert a large gravitational pull on other objects — the two known properties of dark matter.

Until now, this theory could only be tested for primordial black holes heavier than the moon. But as technology has improved, scientists have been able to take sharper and sharper pictures of outer space. The Hyper Suprime-Cam (HSC) digital camera on the Subaru telescope in Hawaii is an advanced piece of imaging technology that can take a picture of the entire Andromeda galaxy (the nearest galaxy to our own) in one shot. Masahiro Takada and his team at the Kavli Institute for the Physics and Mathematics of the Universe in Japan used this camera to search for primordial black holes;

Ha! Thinking B Hussein Obama
> This is known as “cosmic censorship.”
It’s also known as pseudo-religious nonsense.
It’s also known as a big problem when it comes to working out the quantum mechanics and the positional uncertainty that appears to falsify the notion that an event horizon can exist.
Run through the standard Big Bang model and count the number of “and then a miracle happens...” that are required to believe it.
If you find less than a dozen you aren’t really looking.
It’s not mass that is needed as much as a density; that is, a combination of mass and volume. The earth would form a black hole if it was crushed to about 0.7 inches across. But that would of course require an almost impossible amount of energy. Such energy is found in the gravitation potential of very large stars, however. But their event horizon is at least a few miles across, not just 0.7 inches.
Physics is being humble, not just hiding a mistaken path. And dark matter is like the dark continent, or Dark Ages. Got it, LOL
Just had my mind blown on a physics forum in a rather different manner
I got a picture of Luke Skywalker blowing up the Death Star
Most of the folks in the dark matter world are pretty straight up with the fact that it’s basically fudge factor. They did the math on movement and gravity and how much stuff that should mean is out there. And compared that with how much stuff is out there. And came up short, so they put in something to get the T account to balance. Dark matter is basically just a place holder, they’re hoping to find it as actually something, or figure out what went wrong with their math.
“Emporer has no clothes”
I once new a theoretical physicist who worked at John’s Hopkins before I met him in NM. He told me then (prior to 1986) that physics would eventually be forced to come to grips with the theories flaws, because of this exact issue.
He was right then, and now.
You say that as fiction. But remember, Star Wars used physical effects. They actually did blow up the Death Star. Wasn’t as big as it looked, but one of the actual models actually got blowed up.
What is actually happening is that you are looking at a composite image, with most of the data inferred algorithmically by people who assume what they are looking at is a black hole.
It’s not a surprise to see a large scale structure at the center of the galaxy. What it is, exactly, is another question.
What it is infinitely more likely to be than a black hole, is a plasmoid.
What did Dr. Gunter Zoolof’s calculations predict about black holes?
Ok thank you I just did the basic math and knew I was missing something. Then I read your reply and that helps a lot, and thank you for your time and explaining it instead of treating me like I was dumb.
Nope. You’re just pissed your favorite pet theory went down. Black holes are real. Deal with it.
“something with zero mass like light”
Light only has zero rest mass, and since it is never actually “at rest” that seems like a pretty flimsy objection.
“We see effects that may be caused in this manner, or may be caused by other phenomena.”
One could say that about every single scientific proposition ever made. The best science can do is rule out some explanations, and then try to judge which among those that remain can best explain our observations. Still, there will always be alternative explanations that might be true, which science cannot rule out.
“Dark matter” cannot be seen. It is just a theory.
Listen, our equations don’t work - they just don’t reflect reality. What are we going to do? I’ve got it! We’ll invent something that doesn’t exist, and that we can’t see, to plug into our equations so they’ll work.
Eureka! the equations work!
Dummies! the equations still don’t reflect reality!
“Dark matter” is just a place-holder for something they cannot explain..................
I have no “favorite pet theory”.
I am merely interested in knowing what is true.
What is NOT true, and I can assert this beyond a reasonable doubt, is the Big Bang story and certain necessary offshoots such as black holes and neutron stars.
The same institutional corruption and consequent lack of scientific rigor in favor of “consensus” (AKA agreement of grant funders) that is so evident in climate hysteria, also infects the pursuit of the failed Big Bang model.
I can entertain any number of ideas that may be true.
The existence of black holes is not one of them.
> “Dark matter” is just a place-holder for something they cannot explain..................
Dark matter is literally the amount that standard model theory is wrong, when compared to observation.
It’s the Russia collusion of institutional science. They’ll pursue it to the ends of time, if permitted, no matter whether there’s any pertinence to actual reality in their work or not.
“But matter never can go past the event horizon.”
Sure, that is true for matter that exists outside the event horizon after the black hole forms, but what about the matter already INSIDE the event horizon before it forms?
