Black Holes Not Black After All, Theorize Physicists
KentuckyFC (1144503) writes Black holes are singularities in spacetime formed by stars that have collapsed at the end of their lives. But while black holes are one of the best known ideas in cosmology, physicists have never been entirely comfortable with the idea that regions of the universe can become infinitely dense. Indeed, they only accept this because they can't think of any reason why it shouldn't happen. But in the last few months, just such a reason has emerged as a result of intense debate about one of cosmology's greatest problems — the information paradox. This is the fundamental tenet in quantum mechanics that all the information about a system is encoded in its wave function and this always evolves in a way that conserves information. The paradox arises when this system falls into a black hole causing the information to devolve into a single state. So information must be lost.
Earlier this year, Stephen Hawking proposed a solution. His idea is that gravitational collapse can never continue beyond the so-called event horizon of a black hole beyond which information is lost. Gravitational collapse would approach the boundary but never go beyond it. That solves the information paradox but raises another question instead: if not a black hole, then what? Now one physicist has worked out the answer. His conclusion is that the collapsed star should end up about twice the radius of a conventional black hole but would not be dense enough to trap light forever and therefore would not be black. Indeed, to all intents and purposes, it would look like a large neutron star.

So it's not infinite, it just approaches the asymptote. And it's true because Hawking said so.
And most of the posts on this story are worthless jokes or statements meant to make light of stupidity and convey it as a virtue.
Real classy, slashfags. And you all wonder why Dice posts politcally charged stories so much. Because those get 1000+ comments. Stories of a true and interesting scientific nature get less than 50 comments and are mostly just references to a 17 year old meme from a movie that had sharks with lasers strapped to their heads as comic relief in one scene. One scene.
Pathetic. I suggest slashdot.org just redirect to reddit.com going forward.
The Rev. Jesse Jackson now meeting with the Physicists and asking them to create a diversity program for the universe while also insisting that they become members of his Rainbow Coalition.
"We must not allow the progress we've made in astrophysical objects to be eroded by these people who don't know what it is to be black. Black is beautiful. Am I MLK Yet?" The rev. Jackson was quoted saying.
