Hawking Radiation Observed

September 29, 2010

In a very recent study, researchers from Italy have claimed to observe the elusive  Hawking radiations by creating a miniature analog of black hole in the lab. The study which is going to be published in Physical Review Letters would be the first study to observe it after theoretical details were first presented by Stephen Hawkings in 1974.  He predicted that instead of taking in everything, blackholes can also emit thermal radiations. Many have tried to observe the phenomena but have failed so far. This results of this study will be scrutinized and debated in the scientific community in coming days. The experimental set up consisted of high energy ultrashort laser pulses which was focused onto a fused silica glass to create gravitational analogue of black holes.
