Hole In Time

Physicist Moti Fridman and his colleagues at Cornell University, USA, were able to create a “hole in time” by manipulating the speed of light. “Temporal hole” created in the optical-fiber cable with two lenses, special silicon devices that were created prior to accelerate the flow of information on fiber optics. Part of the light passing through a lens faster, and some, on the contrary, begins to move slowly. As a result, appears a dark segment in the cable. Another lens, further along the cable, collects the light back. Everything that happens in an educated dark segment, not fixed.That is, it seemed to disappear into the temporary hole. This is an interesting anomaly lasted only fifteen trillionth second. 

Theoretically, increasing the distance between the lenses can increase this time to the whole of a microsecond, but no more.
