Physicists Moti Fridman and colleagues at Cornell University have managed to demonstrate a time cloaking device – successfully, of course. Basically, this device actually went to "hide" time for 15 trillionths of a second – although such amounts are negligible, we are not sure just how advancements in this field is going to alter the course of mankind’s history. The researchers managed to cause light to pass through a fiber optic cable to compress, followed by decompression, which resulted in a hole or void that existed long enough for there to be a lag between the two.

This cloaking device will compress the light passing through the optical cable by means of a special silicon lens, causing some light to speed up, while other light that passes through it is slowed down. A different lens that is located a little farther up the cable will put the light back together, which means the emerging light looks unaltered, but there was some space in between in reality earlier on.
This sounds like a good way to implement secure communications – imagine embedding your messages in strategic areas of a time lag.
