New Type of Star Can Emerge From Inside Black Holes, Say Cosmologists
KentuckyFC writes "Black holes form when a large star runs out of fuel and collapses under its own weight. Since there is no known force that can stop this collapse, astrophysicists have always assumed that it forms a singularity, a region of space that is infinitely dense. Now cosmologists think quantum gravity might prevent this complete collapse after all. They say that the same force that stops an electron spiraling into a nucleus might also cause the collapsing star to 'bounce' at scales of around 10^-14cm. They're calling this new state a 'Planck star' and say its lifetime would match that of the black hole itself as it evaporates. That raises the possibility that the shrinking event horizon would eventually meet the expanding Planck star, which emerges with a sudden blast of gamma rays. That radiation would allow any information trapped in the black hole to escape, solving the infamous information paradox. If they're right, these gamma rays may already have been detected by space-based telescopes meaning that the evidence is already there for any enterprising astronomer to tease apart."

No sigs in BETA. Beta SUCKS.
...if a star can emerge from Slashdot Beta. That shit is a black hole of user interface hell.
Nerdy news for your nerdy needs? http://www.soylentnews.org Soylent News is people!
Please post this to new articles if it hasn't been posted yet. On February 5, 2014, Slashdot announced through a javascript popup that they are starting to "move in to" the new Slashdot Beta design. Slashdot Beta is a trend-following attempt to give Slashdot a fresh look, an approach that has led to less space for text and an abandonment of the traditional Slashdot look. Much worse than that, Slashdot Beta fundamentally breaks the classic Slashdot discussion and moderation system. If you haven't seen Slashdot Beta already, open this [slashdot.org] in a new tab. After seeing that, click here [slashdot.org] to return to classic Slashdot. We should boycott stories and only discuss the abomination that is Slashdot Beta until Dice abandons the project. We should boycott slashdot entirely during the week of Feb 10 to Feb 17 as part of the wider slashcott [slashdot.org] Moderators - only spend mod points on comments that discuss Beta Commentors - only discuss Beta http://slashdot.org/recent [slashdot.org] [slashdot.org] - Vote up the Fuck Beta stories Keep this up for a few days and we may finally get the PHBs attention. Discussion of Beta: http://slashdot.org/firehose.p... [slashdot.org] [slashdot.org] Discussion of where to go if Beta goes live: http://slashdot.org/firehose.p...

Black holes form when a large star runs out of fuel and collapses under its own weight
Isn't actually it's own gravity? The weight would increase with the gravity, doesn't it?
It's called the Slashdot beta
post! yeah bitches!
Car analogy time: I have gotten rid of vehicles that sucked less than the Slashdot beta. Seriously even that '85 Bronco II where everything was rusty, none of the body panels matched, and that had bad compression on the #5 cylinder sucked less than beta.slashdot.org.
Time to offend someone
So decaying black holes might be another source of gamma ray bursts? Interesting hypothesis. I suppose this would permit a big old star to bounce between being a black hole and a neutron star, depending on the rate of incoming material.
So, do I have to point out the obvious that the /. beta is horribly user-hostile to keep this from getting modded -1 insightful?
I'm not even logged in, and I'm posting an anti-beta comment! Long live Alpha!
"Slashdot Betas form when a large company runs out of ideas and collapse under its own weight. Since there is no known force that can stop this collapse, netizens have always assumed that it forms a singularity, a website that is infinitely filled with whitespace."

FUCK BETA. I want my classic back. And one more thing, FUCK BETA!
.... in Slashdot Beta
love is just extroverted narcissism
Here you can find more information on the topic.
Fuck Slashdot Beta Fuck Dice
...from the black hole known as Beta is a festering pustule of mediocrity -- the ashes of what probably once was the most interesting site on the 'net.
Put another way, Beta sucks so hard it bends light.
Al Carajo con Beta!
The "Civilized World" jumped the shark ca. 1973.
OK, so I understand (vaguely) that this essentially means stuff goes in but doesn't come out.
But if this Planck star bursts forth from a black hole, is any 'information' in a meaningful sense coming back out? Or is the collection of random bits which we defined as 'information' coming back out just a bunch of meaningless noise?
It sounds more like "stuff comes back out, but will have been so mangled by the process that it isn't, strictly speaking, what we'd call 'information'".
I've never been really clear on what is meant by "information" in this context -- it's not like you can figure out that the burst of gamma radiation corresponds to anything specific, it's just a burst of gamma radiation (and whatever else comes out).
Lost at C:>. Found at C.
My first comment ever. Reading since 1997. Looks like boycott is already happening.
From a Slashdot Beta?
Never thought I would see the day...but the reality is not surprising.
I feel the disturbance in the force.
As low number UID slashdoters feel their power crumble away into said black hole.
What's this cosmological physics noise when we are trying to have a discussion about FUCK BETA?
What TFS really means is that out of the suck generated by Beta, a new site will emerge, free from corporate cocksuckery.
Beta: Only slightly better than Facetwat.
The "Civilized World" jumped the shark ca. 1973.
Now that I have your attention, plank stars are explained by one word.. Entropy! That is all!
What I don't get is why people who are experts in cosmetics are talking about stars...
naw... FUCK THE BETA!
This one time in band camp.....FUCK BETA!
We ran into some trouble getting the comments. Try again... na-nu, na-nu!
Slashdot's Beta has proved that it is possible for information to be sucked in and never get out.
WTF is up with article titles that only the first 3 words are visible because of the huge font used?
Slashdot beta - the artificial blackhole created by Dice that Slashdot will be sucked into
I'm glad they used centimeters, otherwise I would not have understood how small it is...
I really like Slashot Beta. Not only does it look & feel nicer, but all stupid units of measure are automatically converted to SI units.
That's 100 am.
"the shrinking event horizon would eventually meet the expanding Planck star, which emerges with a sudden blast of gamma rays"
So, this could be the source of Gamma Ray Bursts?
http://en.wikipedia.org/wiki/Gamma_ray_burst
Fuck the Black Hole!!!
And I'm someone who has a high tolerance for sucky websites.
After Slashdot's Beta.
you're doing it wrong.
CLI paste? paste.pr0.tips!
Seriously, fuck beta!
Neither know shit, they just throw shit at the wall and hope something sticks when someone finally gets around to testing.
For Dice, that testing will come when they force me to use the shitty new beta version of the site. Spoiler: I won't stick around.
Fuck beta. Fuck Dice.
Dice released their 4th quarter filing...and it does not cast Slashdot in a good light:
Slashdot Media was acquired to provide content and services that are important to technology professionals in their everyday work lives and to leverage that reach into the global technology community benefiting user engagement on the Dice.com site. The expected benefits have started to be realized at Dice.com. However, advertising revenue has declined over the past year and there is no improvement expected in the future financial performance of Slashdot Media's underlying advertising business. Therefore, $7.2 million of intangible assets and $6.3 million of goodwill related to Slashdot Media were reduced to zero.
Looks like running AdBlock on Slashdot and turning off ads may soon be the cause of their demise...
Mr Malda, this site was once your little baby that you ran from your dorm. You've moved on to other things. We miss you but that's fine we can understand.
But why couldn't you have left it in better hands? Why not a fucking not for profit Slashdot foundation. Dice is a fucking Answers.com wannabe. They're fucking butchering Slashdot.
DOWN WITH BETA
And say I think that most of the community thinks Slashdot Beta sucks.
Oh, wait, it's in a black hole.
We get it, you don't like the beta. Now will you quit with your rants? All you are doing is making slashdot unusable for everyone. If slashdot dies, it won't be from the beta, it will be from people not wanting to expend the effort to find real comments.
Enough already!
I have a proposal for the slashdot powers that be. How about all anonymous coward postings be automatically flagged for moderation and only those related to the article at hand be released?
Please, please, this is like a bad Star Trek TNG plot....
... and I am not trying to be condescending here, I'm genuinely curious. What is a 'Planck star'? Is it like a regular star? Does this mean that we won't eventually end up with a universe full of black holes? Does this mean that there matter can actually escape from a black hole and that there are no white holes?
.
I doubt they said that, and whether they did or not the data is not there for any enterprising astronomer to tease out.
Any black hole of any realistic mass (say, 2.5 Solar masses and up) will take much, much longer than the current duration of our universe to evaporate. So, maybe this will happen, maybe not, but it for sure hasn't happened yet. Come back in 10^100 years and let's talk,
Yes, M.T. Cicero is dead. And if Slashdot keeps pushing this beta despite complaints that the beta is pain for its own sake (dolorem ipsum dolor), Slashdot will itself go as dark as a black hole.
If you hate Beta, DO NOT VISIT Slashdot on 2/7!!
How you you show them Beta sucks? You drop their ad impressions!
Keep Classic/Fix Beta, or we walk.
Is it just my observation, or are there way too many stupid people in the world?
HI. I posted this to see what it would look like on the beta website.. If they call it beta isn't it supposed to be working? maybe they will fix Slashdot Beta and everyone will be happy again. Can you see this? I can't. What is wrong? Is this why they call it beta? I hope someone will be able to fix this because I am not happy it is not working. Maybe after the beta test is over it will work. It sure doesn't work now. I am getting even sadder. It seems to work on the old site but the beta site is not very good and is making me sad. sad sad sad. I am not very happy when Slashdot makes me very sad. What will happen to me when classic is GONE!!! I will try posting this on YouTube PLEASE HELP ME!!!!! A little history of Slashdot courtesy of Wikipedia. What it was before It was destroyed by Beta. I tried posting this before but could not see it with beta. What am I doing wrong? I guess I will have to keep on trying until I can read it. Maybe that is why they call it beta. I am sure they will fix everything and everyone will be happy again. Tell me if you can read this. I am really upset that I can not see my own posts Maybe that is why they call it beta. I am sure they will fix everything and everyone will be happy again. Can you see this? I can't. What is wrong? Is this why they call it beta? I hope someone will be able to fix this because I am not happy it is not working. Maybe after the beta test is over it will work. It sure doesn't work now. I am getting even sadder.PLEASE HELP ME!!!!! The origins of the site now known as Slashdot date back to July 1997 when Rob "CmdrTaco" Malda started a personal website called Chips & Dips, which featured a single "rant" each day about something that interested him – typically something to do with Linux or open-source software. At the time, Malda was a student at Hope College in Holland, Michigan, majoring in computer science. The site became Slashdot in September 1997 under the slogan "News for Nerds. Stuff that Matters," and quickly became a hotspot on the Web for news and information of interest to computer geeks.[4] The name "Slashdot" came from a somewhat "obnoxious parody of a URL" – when Malda registered the domain, he desired to make a name that was "silly and unpronounceable" – try pronouncing out, "h-t-t-p-colon-slash-slash-slashdot-dot-org".[5] By June 1998 the site was seeing as many as 100,000 page views per day and advertisers began to take notice.[4] By December 1998, Slashdot had net revenues of $18,000, yet its Internet profile was higher, and revenues were expected to increase. On June 29, 1999, the site was sold to Linux megasite Andover.net for $1.5 million in cash and $7 million in Andover stock at the IPO price. Part of the deal was contingent upon the continued employment of Rob Malda and Jeff Bates and on "the achievement of certain milestones". With the acquisition of Slashdot, Andover.net could now advertise itself as "the leading Linux/Open Source destination on the Internet".[6][7] Andover.net eventually merged with VA Linux on February 3, 2000,[8] which changed its name to SourceForge, Inc. on May 24, 2007, and became Geeknet, Inc. on November 4, 2009.[9] Slashdot's 10,000th article was posted after two and a half years on February 24, 2000,[10] and the 100,000th article was posted on December 11, 2009 after 12 years online.[11] During the first 12 years, the most active story with the most responses posted was the post-2004 US Presidential Election article "Kerry Concedes Election To Bush" with 5,687 posts. This followed the creation of a new article section, politics.slashdot.org, created at the start of the 2004 election on September 7, 2004.[12] Many of the most popular stories are political, with "Strike on Iraq" (March 19, 2003) the second-most-active article and "Barack Obama Wins US Presidency" (November 5, 2008) the third-most-active. The rest of the 10 most active articles are an article announcing the 2005 London bombings, and several articles about Evolution vs. Intelligent Design, Saddam Hussein's capture, and Fahr
your whining says more about you than you complaint.
Yea, we get that you don't like the beta.
Now get a life instead of hanging around the comment board all day.
Normal, classic, Slashdot *works*. It requires no makeover.
Please make Beta stop.
Unplugging 2/10-2/17
paid me to pound it from the back. In a bathroom stall. AT WALMART. Beta's mom cleaned up the mess.
Ooh, that's nasty. Well, they can't say they weren't warned.
To be paradoxical: Beta looks less 'trashy', as if everything is moderated,
as if there's 'no drive by posting' anymore, as if the NSA is super-super-
supermoderator, and we're al thinking of the kids right now.
Beta Sucks? Beta Kills!
slashcott.com
Which seem to have been sucked down a black hole called Beta. When will the real content return?
"When a black hole consumes energy and releases a Planck star, do either events reduce the entropy of the system?"
Probably when the Planck star re-emerges, back into the observable universe, like it's never been away, entropy is fuck beta conserved. Having just read the Wikipedia article (I'm an expert now) on the 2nd law of thermodynamics, there's an interesting fuck beta bit about gravitational systems being fuck beta different from normal ones in that the more fuck beta massive a black fuck beta hole becomes, the lower it's fuck beta temperature, so fuck beta fuck beta fuck beta?
Fuck Beta!
Sig (appended to the end of comments you post, 120 chars)
The only good thing about the beta is being able to switch to the classic theme. I can't even follow comments right, there used to be interesting stuff in the days before the beta, now I can't really tell unless I switch to classic. I looks like a crappy blog designed to appeal to tasteless apes, the kind of which roams facebook, slate and the likes.
cool
Shouldn't that be either 100am (atto-meters) or 10^-16m (meters)?
Why mix the prefixes and powers? It makes you look stewpid.
First black holes swallow everything. Then they don't. Then Professor Wheels says they don't even exist. Now they're shitting out stars!
astrophysicists have always assumed that it forms a singularity, a region of space that is infinitely dense. Now cosmologists think quantum gravity might prevent this complete collapse after all.
I've been wondering if this (singularities not actually forming because some of unknown process) might be the case for years, but only because I found singularities a freaky concept.
systemd is Roko's Basilisk.
The event horizon is not a special place, when you are close by, it looks just like any other close by place. I believe it's even in a slightly different location depending on where you are outside of it. The standard definition is relative to an oberver at infinity. If you were close to the standard definition of the event horizon, it would appear to be closer to the center yet.
My understanding about black hole evaporation is that it occurs at a very slow rate. I suspect that you are not going to actually see them evaporate until the universe is a lot colder and there is much less for them to feed on, so they can actually have a consistent net loss of mass for billions of billions of years.
So gamma rays we see now are not coming from these Planck stars.
Not another sciencey thing that Ham gets to imagine a deity created...
TFA says:
[the] force that stops an electron spiraling into a nucleus
It suddently strikes me that I never wondered about it: what prevents the electron from crashing into the nucleus?
Or perhaps you were aiming for 10^-16m?
It's kind of like people who are experts in bland, content-ruining, low-contrast, lower-functionality websites are talking about /.:
Nothing good comes of it.
You are in a maze of twisty little passages, all alike.
... and the beta sucks.
You are in a maze of twisty little passages, all alike.
the new interface flapping blows. i have been a long time reader. and i enjoy it. this new crap.... blow it blow me slash dont if ya dont keep it normal
Let’s take your scenario: a proton/anti-proton pair of virtual particles pops into existence from the quantum vacuum near the event horizon and the anti-proton spirals into the black hole, meaning that the proton no longer has it’s antiparticle to annihilate against. (Clearly we’re talking about energy in terms of mass-energy terms here.)
OK, the original virtual-particle pair ‘borrowed’ energy from the vacuum; that debt must be paid back because the universe’s energy must be conserved. If the energy can no longer be ‘returned’ by annihilating the virtual particles, the ‘energy debt’ must be subtracted from the mass-energy of the black hole. This, essentially, is the process of Hawking radiation that causes a black hole to evaporate: it’s kind of like cosmic repo-men demanding dues from the black hole. The universe wants to be made whole and it gets it’s due from wherever it can. If the repo-men can’t find you and repossess your unpaid television, they annoy your old folks instead.
Here’s where the quantum-information question arises: is there any ‘information’ contained in that debt repayment? The classical view says ‘no’: it’s just the right amount of mass-energy, but all other parameters are random (spin, charge, bla bla bla). Quantum mechanics cannot accept that and insists that the information must be expressed as energy radiating with exactly the right characteristics. As if the dollars extracted from your parents must also, in some sense, carry a hint of that TV you haven’t paid for.
"Place me in the company of those who seek Truth, but deliver me from those who believe to have found it."
Waaah, they changed a bit of the user interface, the internet is ruined forever. Get a blog or something.
Isn't this P. Mazur's Gravastar?
Black holes have been for a long time known to emit radiation Iong an axis perpendicular to there rotation.
