According to him, when hot objects exert heat into space, the ultimate fate of a black hole is to evaporate out of existence.However, the rules of the quantum world dictate that information is never lost.
Hawking spoke with a computer-generated voice for decades after losing his voice due to Lou Gehrig’s disease, a neuromuscular disease also known as ALS.
He was diagnosed as a 21-year-old graduate student in 1963, and doctors gave him less than three years to live.
“We don’t know that Hawking entropy accounts for everything you could possibly throw at a black hole, so this is really a step along the way,” said Perry.
“We think it’s a pretty good step, but there is a lot more work to be done.” Marika Taylor, professor of theoretical physics at Southampton University and a former student of Hawking’s, said: “Understanding the microscopic origin of this entropy – what are the underlying quantum states that the entropy counts?
According to co-author Malcolm Perry, a professor at Cambridge University, the information paradox was “at the center of Hawking’s life” for over 40 years.
In 1915, Albert Einstein published his theory of general relativity, which described how gravity arises from the spacetime-bending effects of matter.
When he died at age 76, he was interred at Westminster Abbey in London between the remains of Isaac Newton and Charles Darwin.
Stephen Hawking’s last scientific paper – which was finished days before the British physicist’s demise – has been composed and posted online by his partners at Cambridge and Harvard colleges.
The paper named Black Hole Entropy and Soft Hair handles with the end result for data when it falls into a blackhole, an issue that hypothetical physicists allude to as ‘the information paradox.
It was completed in the days before Hawking’s death in March, and has now been written up by his colleagues at and posted online.
