Scientists stop light completely for a record-breaking MINUTE by trapping it inside a crystal
• http://www.dailymail.co, By Abigail Frymann 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.'
