Welcome everyone to universe evolution.well this a compulsory site one(universe lovers) has to look through.. i'll be posting some thrilling,mysterious facts about our solar system...
LIGHT CAN BE STOPPED?
Well before going for the question i'll quickly post some properties abt light. well "light" can travel with a speed of 3 lakh m/s where as in miles it is 6.702 * 10^8 miles/hour.
Scientists stop light completely for a record-breaking MINUTE by trapping it inside a crystal!
Scientists in Germany have succeeded in stopping light - the fastest thing in the universe - for a whole minute, smashing earlier records.
Researchers at Darmstadt Technical University achieved the remarkable feat by trapping it in a crystal.
In a paper published this month in the journal Physical Review Letters, the scientists explained how they stopped the light using a technique called electromagnetically induced transparency.
At full pelt, light would normally travel about 11 million miles in one minute – equivalent to more than 20 round trips to the moon.
'One minute is extremely, extremely long,' Thomas Krauss, Professor of optoelectronics at the University of St Andrews, UK, commented to the New Scientist. 'This is indeed a major milestone.'
The physicists, Professor Thomas Halfmann, Christian Hubrich and PhD student Georg Heinze, also used the same technique to store and then retrieve an image consisting of three stripes. 'We showed you can imprint complex information on your light beam,' said researcher Georg Heinze.
