Scientists just proved that Hawking radiation is real



Back in 1974, the famous theoretical physicists Stephan Hawking had theorised that black holes don't absorb everything that falls into them. Rather, they emit some radiations which are of the order of a billionth of a kelvin. This theory was based on a fundamental principle in thermodynamics that everything in the universe has to emit some radiation, and nothing is an ideal black body in reality. This radiation was named the Hawking radiation. However, scientists at that time couldn't prove it practically as they didn't have a black hole with them or proper equipments to simulate it.


But now they have suitable devices to simulate and create conditions like a black hole. And a team of scientists recently have made such an intricate setup in the lab, and were able to observe the Hawking radiation!
A setup to simulate the conditions in a black hole might seem risky and fearful to many, as many of us have such misconceptions that it would suck the entire earth in it. But, actually such setups have no threat on humanity, as these black holes (if they are created) exist for just a fraction of seconds and are too small.
These setups involve a laser beams with optical fibres or sound waves or water which are allowed to go through some specially designed tanks.
In this particular setup, the team allowed the laser beams to travel through optical fibres and hence were able to simulate conditions similar to the event horizon of a black hole. Although in such conditions, the laser beams aren't able to escape the optical fibre- just like a black hole. But, in this experiment they observed that some radiation was able to escape. This proves that Hawking was right almost half a century ago.
However, like any other science projects this one also needs to be verified through continuous repeated experiments in order to observe the same effects. Then only, we can draw any conclusions. But, for the time being, we may say that Hawking radiation does exist!
