American physicists invent a device for the disappearance of the time
Physicists announced receiving funding from the U.S. Department of Defense that they designed a system "disappearance" time able to make the event Not monitoring for a fraction of a second.Scientists inspired this device checksum of research on the "robe disappearance" promoted by the famous Harry Potter. But instead of the device to hide a certain purpose in somewhere, veiled from sight at the time, reported the study published in the journal "Nature" British.
He says Moti Friedman, research director of Cornell University in New York ran this research, "The results that we have reached an important step towards the development of the robe of a comprehensive time and place."In order to design the device, based on scientists to the properties of the visible light spectrum and that the different colors that move quickly pose a little bit different.It starts robe disappearance "timeline" to issue a green beam of light in a cable made of optical fibers. Beam then passes this divide lens to Doin: blue light spreads a little more quickly than the original Green Beam speed and red light slightly slower.Is increased difference in speed Behma the development of a transparent barrier between them. At the end of the day, formed the "time gap" between Beam Red and Blue Beam, which reflect the optical fiber.Although this gap is very small and duration only 50 Bekothanih, but it is enough to enter the shipment of the laser frequency different from the frequency of the light that crosses the optical fiber.After enter shipment laser to a short period, subject to beam red beam and blue mirrored who shall process a new barrier to accelerate the beam red and slow down the blue and then re-reunion in a beam lens and one green.The remaining shipment laser that lasts for forty Bekothanih, exist but are unobservable because they do not belong to a stream of photons your green beam.Robert Boyd explains Zemin Shi of the University of Rochester in New York that this process is similar to the intersection between the railway and the road crowded. When the train arrives, the car stop at the intersection, what is happening "gap" in traffic.Once the train passes even speed up the cars that were parked in order to catch the other cars.For watching the road from a distance, looks completely normal traffic remains no evidence on the passage of the train at the intersection.And Boyd and Shi indicates that the next goal of the researchers is to achieve increased "time gap" that hide an event enough.He considered that the time of disappearance can be used to ensure the security of communications because this process allows segmenting optical signals and make a different move quickly before re-collected. Thus, it becomes very difficult to penetrate the data.And Moti team gets Friedman on the part of the funding agency of the Defense Advanced Research Projects of the U.S. Department of Defense and on the development of future technologies close to science fiction may be used for military purposes.This agency has developed in the late sixties a system for transferring data between computers, paving the way to the invention of the internet.
