Change history with 'time gown'

Researchers at Cornell University in Ithaca, New York, for the first time demonstrate that it is possible to obscure a particular event in time, creating what is expected as "historical editing."

MOTI Fridman and his colleagues fired a beam of light onto an optical fiber and a pair of stars called "time lenses." Between these two lenses, the researchers created a small bubble, or can be said to be the distance in the flow of light. In this lightning-fast moment, this is only the smallest part of a millisecond and acts like a time loophole, hiding the event in the shorter duration of the light as if it had never occurred.

The team will present its findings at the 2011 Annual Meeting of the Optical Association (OSA), the Limits of Optics (FiO), held in San Jose, California next week.

To test the effectiveness of the 'time gown' , the researchers created direct light pulses between the two lenses. Repeated pulses like clock with 41kHz speed. With this "robe" , researchers can detect a regular rhythm. By the actions on the 'time gown' were synchronized with the light pulses, indicating that the events took place has been deleted.

Unlike space-based stealth, which requires the use of metamaterials (creating specially designed materials), the 'time gown' is designed based on the basic properties of light and Operation in space and in time conditions is still limited.

Areas affected by the 'time gown' are about 6mm long and can last as much as 20 trillionths of a second. The length of the stealth area and the length of time it can operate are still limited - mainly the polar velocity of light. Invisibility for a longer time will cause instability in the system

In addition, in order to achieve any measurable macromolecular effect, conducting scale trials between planets will be necessary.
