Physicists demonstrate a time cloaking device

Physicists Moti Fridman and colleagues at Cornell University have successfully demonstrated a so-called time cloaking device that is able to “hide” time for 15 trillionths of a second. In a paper published on arXiv, the researchers describe how they were able to cause light passing through a fiber optic cable to compress, than decompress, causing a hole or void to exist, long enough for there to be a lag between the two.
