New Type of Star Can Emerge From Inside Black Holes, Say Cosmologists 193

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."

    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...

    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

    As I understand it, that's almost exactly it. The catch is that the universe is now 2 protons heavier than it was, and it can't keep them. "Normally" the proton and antiproton would recombine and annihilate and it would be gone, but now that they're separated that can't happen. So the black hole's mass gets debited 2 proton masses. So the final result is that the hole is down 1 proton mass and the rest of the universe is up 1 proton mass.

I tell them to turn to the study of mathematics, for it is only there that they might escape the lusts of the flesh. -- Thomas Mann, "The Magic Mountain"
