A cloak in time conceals events.

The article looks at a report published on July 11, 2011 online at arXiv.org, by researchers including Moti Fridman of Cornell University, on temporal cloaking. Scientists were able to tear a temporary hole in a beam of light by using a time lens. Topics include the use of metamaterials, manipulation of light, and how the experiment was completed in a fiber-optic cable vacuum.
