Darpa Research: Pentagon Scientists Create 'Time Holes' To Hide Events As They Happen
We're used to the idea of soldiers working in the dark or even via remote control.
But how about working in an cloud of invisibility that not only masks objects - but actual events?
Well, catch up. American scientists working for the Pentagon have published research which demonstrates how to hide history as it happens.
A team at Cornell University working with the Defense Advanced Research Projects Agency (Darpa) has published a report in the journal Nature demonstrating how to hide an event for 40 trillionths of a second.
The effect, described as "spatio-temporal cloaking", depends on the ability to slow the flow of light from events as they occur - making them impossible to observe.
