Pah!  <a href=\"http:\/\/www.technologyreview.com\/blog\/arxiv\/26992\/\">First Demonstration of Time Cloaking<\/a>&#8230;<\/p>\n<blockquote><p>Moti Fridman and buddies, at Cornell University in Ithaca [&#8230;] have designed and built a cloak that hides events in time. Time cloaking is possible because of a kind of duality between space and time in electromagnetic theory. In particular, the diffraction of a beam of light in space is mathematically equivalent to the temporal propagation of light through a dispersive medium. In other words, diffraction and dispersion are symmetric in spacetime. [&#8230;] The device has some limitations. The Cornell time cloak lasts only for 110 nanoseconds &nbsp; that&#8217;s not long. And Fridman and co say the best it can achieve will be 120 microseconds. <\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Invisibility cloak? Pah!
