black holes

I thought this was interesting: Researchers spot black hole feeding at 40x its theoretical limit (Ars Technica) This "theoretical limit" is called the Eddington Limit, but it doesn't seem to actually hold true. It does seem to solve the problem of how supermassive black holes came to be so...

If anyone has been following along since Stephen Hawking died. Black Holes Finally Proven Mathematically Stable There is still much work left to be done as: If some one would care to produce a 200 page summary, it may help my lay comprehension as: :boggled:

Mysterious, ghost-like black hole may have been discovered by UC Berkeley researchers Isn't that crazy, if true? Something you can't even see except for how it lenses the light behind it. Sometimes you see black holes because they give off X-rays (from the accretion disk of course, not the...

And by immanent I mean not sometime in the next million years. If the model is correct it will happen sometime this year! https://www.science.org/content/article/crash-titans-imminent-merger-giant-black-holes-predicted

All it takes is intelligence, hard work and . . . a supercomputer. Astrophysicists identified the origin of supermassive black hole flares Largest-ever simulations suggest flickering powered by magnetic ‘reconnection’. No electricity involved. :duck:

Dark Matter mystery solved? And the answer is . . . Ta Da . . . Black Holes! We may finally be able to test one of Stephen Hawking's most far-out ideas https://www.livescience.com/testable-primordial-black-holes-theory OK. So maybe soon then. ;)

Dr. Rebecca Smethurst, aka Dr. Becky on YouTube, has released her latest paper on her current research into Supermassive Black Holes and how they get bigger. Previously it was thought that most of their mass comes from the combining of the Black Holes when galaxies collide, but her team has...

Well maybe . . . . eventually. A New Idea to Harness Energy From Black Holes https://www.universetoday.com/149716/a-new-idea-to-harness-energy-from-black-holes/ But we'll need an awfully long extension cord. :( Just you wait.

In all honesty this is beyond my understanding but the cosmological implications are, to say the least, interesting. and https://www.quantamagazine.org/the-black-hole-information-paradox-comes-to-an-end-20201029/

LMXB: low mass x-ray binary; i.e. as low mass star and a stellar-mass black hole in orbit around each other. Emits copious amounts of x-ray radiation. Based in Paice+ (2019), "A black hole X-ray binary at ∼100 Hz: multiwavelength timing of MAXI J1820+070 with HiPERCAM and NICER" (link to...

Well, here comes another black hole question from yours truly. I'm sure everyone is surprised ;) So I've heard arguments from physicists before, saying that the planet near a blackhole in Interstellar would be unstable, or bathed in lethal radiation from the accretion disk, etc. But it just...

Before I start, let me state that I'm not pushing any explanation of my own, because I don't even have one. Which is unsurprising, I guess, since I'm not a physicist. I genuinely get a brainfart just trying to think about how it swallows matter, and I'm hoping someone more knowledgeable can help...

Groundbreaking discovery confirms existence of orbiting supermassive black holes http://www.phys.unm.edu/~gbtaylor/astr422/ARP/e_0402.pdf Really cool.

Quote: Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves. Though there have been several other suspected, similarly booted black holes elsewhere, none has been confirmed...

Well... no, actually they didn't. NASA just saw something come out of a black hole for the first time ever They saw an x-ray pulse from the region around the black hole, but there's nothing to suggest that it came "out of" the black hole itself. My guess is that it is a result of the...

I expect that common sense says these big entities are most easily built when all matter is close together. http://phys.org/news/2016-05-hubble-clues-birth-supermassive-black.html

The Quantum Cosmology Inverse Theory Juan (Jay) Sadie Abstract This theory postulates an inverse way to look at what is large and what is small. When we talk about quantum mechanics we automatically presume that things are smaller at this level. What this theory proposes is that as we drill...

Okay. Here's hoping to hear from some of you theoretical physicists and cosmologists. Particle-antiparticle pairs are popping into existence all the time, but the energy of the universe as a whole is conserved because they annihilate each other quickly. When this occurs near the event horizon...

Well, the last part is probably not true - but the first part is!!:http://news.yahoo.com/trove-black-holes-discovered-andromeda-galaxy-113951504.html Click on the tiny picture for neatness!!:):):)

So I'm watching a few shows last night, one on Supermassive Black holes, and another on Cassini / Huygens, and I found both to be fascinating. I think super-massive black holes to be the birth of a galaxy, sort of like a mini big-bang for every galaxy we know of. I also wonder who specifically...

I can't post links, but on a physicists blog (Google "black hole without singularity", it's first hit), he speculates it's possible to achieve a black hole without a singularity. If it didn't have a singularity, could you get out? Or do all your future paths (not phrasing that right, I'm...

Sometime in the my dim distant past, before the days of the Internet when paper still ruled, I remember reading an article in ISTR a science fiction magazine that claimed the the Universe was a Black Hole because it was of the right density to be one -- the size of a black hole been dependent on...

According to the Electric Universe folk at the Thunderbolts web site, black holes do not exist. According to the EU folk, black holes are not even consistent with Einstein's general theory of relativity. As intellectual cover for their position, the EU folk cite a series of papers that have...

I will admit to ignornace here but Black Holes as I understand it are collapsed stars that I can understand, they are not holes as such are they? If they are a collapsed star surely there is some solid mass at the core still? I certainly do not have enough knowledge nor understanding of the...

Sometimes I ponder things, and some of those ponderations lead me to suspect that I'm misunderstanding some of the fundamentals. For the sake of discussion, let's take it as a given that the universe is expanding, and that the rate of expansion is increasing, and that eventually this will...

From The Washington Post: Fascinating, and there are some great NASA images along with the story. I thought it might be of interest to others. I hadn't realized that there were different kinds of black holes. Also, the story says this one is in "our neighborhood" (maybe I should have posted...
