A physicist from United States may have finally solved the Stephen Hawking's black hole puzzle, TOI is reporting. 

Black holes have been a subject of countless mysteries for physicists across the globe. The fascinating monstrous entities have such an intense gravitational pull that even light can't escape from them.

The debate attained the momentum once again when recently Hawking posted on a blog on January 22, 2014 that invisible boundaries of the black holes don't exist. 

"According to the laws of quantum physics, information can't disappear," said Professor Chris Adami from Michigan State University, according to TOI. "A loss of information would imply that the universe itself would suddenly become unpredictable every time the black hole swallows a particle. That is just inconceivable. No law of physics that we know allows this to happen." 

According to Adami, the solution is the information contained in the stimulated emission of radiation which must accompany the Hawking radiation. He added that stimulated emission made the black hole glow in the information that it swallowed. 

"Stimulated emission is the physical process behind LASERS (Light Amplification by Stimulated Emission of Radiation). Basically, it works like a copy machine: you throw something into the machine, and two identical somethings come out. If you throw information at a black hole, just before it is swallowed, the black hole first makes a copy that is left outside. This copying mechanism was discovered by Albert Einstein in 1917, and without it, physics cannot be consistent," Adami said. 

"While a few people did realize that the stimulated emission effect was missing in Hawking's calculation, they could not resolve the paradox without a deep understanding of quantum communication theory."
