Light can Pass through Black Hole, Says Stephen Hawking

By combining 'quantum mechanics' and 'general relativity', Stephen Hawking has now come to a decision that 'event horizon' does not exist and light can pass through 'black hole'. The acclaimed theoretical physicist affirmed in 1974 that when a black hole dies, it will take everything along with it.

Event Horizon is an area around a black hole from where light and matter cannot escape due to gravitational pull and is also called as 'point of no return'. But after 40 years, Hawking claim that black holes does not have 'event horizon', but have 'apparent horizon' that can vary in shape, leaving the potential for light to escape.

Hawking said on his 70th birthday this month that his earlier information on 'Black hole' was his 'biggest blunder'. 'Quantum mechanics' and 'general relatively' have always been a controversial theories in physics.

'Quantum mechanics' explains matter and energy on an atomic and subatomic scale and focuses on a micro scale. Whereas, 'general relatively' explains wrapping of space-time as gravity and focuses on macro scale.

From the prospective of 'Quantum mechanics', some information can escape from black hole, but this is opposite in case of 'general relatively' theory. But, Hawking has proved with his combination of his two theories that black holes emit radiation.

'Hawking radiation' illustrates that light can escape through black hole, leading to loss of energy and shrinkage of objects.

Some of the Physicists while speaking to New Scientist and Nature state that they are having doubt about the Hawking's conclusion that whether a black hole without an event horizon is possible or not.
