Mighty light

Down to Earth - - ANALYSIS -

de­vice can emit light as pow­er­fully as an ob­ject 10,000 times its size. Re­searchers have cre­ated an ar­ti­fi­cial ma­te­rial in which the wave­length of light is much larger than in a vac­uum, which al­lows light waves to res­onate more pow­er­fully. The de­vice con­denses light to a size smaller than its wave­length, mean­ing it can gather a lot of light en­ergy, and then scat­ters the light over a very large area.
