Hawking resolves black hole riddle
After nearly 30 years of arguing that a black hole destroys everything that falls into it, Stephen Hawking is saying he was wrong.
In an announcement that has sent waves of excitement through the rarefied world of astrophysics, Prof Stephen Hawking claims to have solved one of the greatest mysteries of black holes, reports the Telegraph, London.
The new theory, which solves a major paradox about the most mysterious objects in the universe, has generated a flurry of excitement among his Cambridge colleagues, the Telegraph said.
'Black holes are regions of space where the gravitational force is so strong that nothing, not even light, can escape. Once thought to be purely destructive forces, they are now thought to play a crucial role in galaxy formation. Cosmologists believe that there are many types of black hole, ranging from mini holes with the mass of a small mountain to super-massive holes that lie at the centre of galaxies,' it said.
Their gravitational force is so powerful that everything is sucked inside. It was traditionally thought that once matter and light pass a black hole's "event horizon", then it can never escape.
'In 1975, Prof Hawking made his most important contribution to cosmology by proposing that black holes emit tiny amounts of radiation - known as "Hawking radiation". Eventually, all black holes will evaporate. He also claimed that his radiation contained no "information" about the matter sucked into the black hole,' said the article.
Once the black hole evaporates, all information about the black hole is lost. But under the laws of quantum mechanics describing the behaviour of the universe at the scale of individual particles, such information cannot simply disappear, the Telegraph said.
'For 30 years Prof Hawking tried to get around the paradox by suggesting that the rules of quantum physics were different inside black holes - a solution that many colleagues were unhappy with,' the article said.
Now, it seems that Hawking has an answer to the conundrum and the physics community is abuzz with the news. Hawking requested at the last minute that he be allowed to present his findings at the 17th International Conference on General Relativity and Gravitation in Dublin, Ireland on Wednesday, said the New Scientist.
"He sent a note saying 'I have solved the black hole information paradox and I want to talk about it'," New Scientist quotes Curt Cutler, a physicist at the Albert Einstein Institute in Golm, Germany, who is chairing the conference's scientific committee, as saying.
"I haven't seen a preprint [of the paper]. To be quite honest, I went on Hawking's reputation."

OFFICIALS OF the Bush administration are said to be pondering what power they have -- or should seek --
to postpone national elections in November in the event of terrorist strikes aimed at disrupting the democratic process.
The Bush people should drop the idea, lest the hint that terrorism could curb the rights of Americans be an added incentive to our enemies.

Buddhism begins with a man.
In his later years, when India was afire with his message, people came to him asking what
He was. Not “Who are you?” but “What are you?”
“Are you a god?” they asked.
“No.”
“An angel?”
“No.”
“A saint?”
“No.”
“Then what are you?”
Buddha answered, “I am awake.”
Those who are awake, live in a state of constant amazement.
As you walk and eat and travel, be where you are, otherwise you will miss most of your life.
The way cannot be forced. The Fruit falls from the Tree when it is ripe.
If you can't find the truth right where you are, where else do you think you can find it?
If you wish to feel the divine, feel the wind on your face and the warm sun on your hand.
To meditate is to listen with a receptive heart.
Take time everyday to sit quietly and listen.
Do not blindly believe what others say, even the Buddha.
See for yourself what brings contentment, clarity and peace. That is the path for you to follow.
When our heart opens, we will realize that we belong just here.
Good-humored patience is necessary with mischievous children, and your own mind.
If you could see the miracle of a single flower clearly, your whole life would change.
Even loss and betrayal can bring us awakening.
Words have the power to destroy or heal. When words are both true and kind, they can change our world.
We are what we think. All that we are arises with our thoughts.
With our thoughts we make the world.
