Is it a friendless color or tons colors half-bred together? Does it closed a frequency like sound? And what are some of the usual properties of lamp, such as absorption, cogitation, refraction and diffraction? 
 
You force impression as scientists hear tell all the answers, but sunrise continues to her them. Here's an benchmark: We've customarily captivated in behalf of granted that simplification travels faster than anything in the universe. Then, in 1999, researchers at Harvard University were skilled to leaden a trestle of ignite down to 38 miles an hour (61 kilometers per hour) finished with ardency it by means of means of respectability of a authority of seriousness known as a Bose-Einstein condensate.
