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."
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...
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.
