Stephen Hawking's wildest theories proved: Here're some very popular
New Delhi : Scientist Stephen Hawking is no more with us but his theories will remain immortal for the whole world. He was a brilliant physicist who has come up with strange science facts which are difficult to prove. For instance, his black hole theory is a biggest achievement in science.
In 1974, Hawking theorized that black holes emit some kind of radiation, called Hawking radiation and now, after nearly fifty years, researchers have experimentally found the evidences for his theoretical radiation.
It is known to all that black holes theoretically suck in everything, even light, but it’s not technically true that nothing can ever escape them. But, if that were the case, black holes would violate the laws of thermodynamics. Everything in the universe needs to radiate heat, and black holes are no exception.
Then, how exactly do they radiate heat? The question was a big mystery until the theories of Hawking.
Hawking theorized that this radiation was happening because of some effect relating to quantum mechanics, although this was difficult to prove because no scientists ever had any black holes around to test it.
However, some scientists have been able to use extremely complicated setups to simulate the effects of a black hole in the lab, and one of these setups was recently able to observe Hawking radiation first hand.
In the experiment, researchers sent laser light through an optical fiber in a precise way to simulate the edge of a black hole. Generally, in such kind of experiment, no light can escape the fiber, just like in a real black hole. But by stimulating the entire contraption with another laser, the team was able to get some radiation out.
Therefore, Stephen Hawking might be right. But researchers suggest that the experiment need to be repeated and improved before anyone starts drawing conclusions.
