The tiny difference in speed is then accentuated by placing a transparent obstacle in front of the two beams. Eventually a time gap opens up between the red and blue beams as they travel through the optical fibre. The gap is tiny -- just 50 picoseconds ...

It works by separating light into its fundamental wavelengths, or slowing the red waves and speeding up the blue. A gap forms in a beam, leaving a small window for an optical illusion. As light passes through another set of fibers, which slow the blue ...
Engadget - Jan 5, 2012
The feat is performed by separating light into more fundamental wavelengths, first by slowing the red and speeding the blue. A resultant gap forms in the beam, which leaves a small window for subterfuge. Then, as the light passes through another set of ...
Washington Post - Jan 4, 2012
This is all happening in beams of light that move too fast for the human eye to see. Using fiber optics, the hole in time is created as light moves along inside a fiber much thinner than a human hair. The scientists shoot the beam of light out, ...

In this illustratio, an art thief walks into a museum and steasl a painting without setting off laser beam alarms or even showing up on surveillance cameras. WASHINGTON – It's one thing to make an object invisible, like Harry Potter's mythical cloak. ...
Washington Post - Jan 4, 2012
The lightening and darkening that occurs when a beam of light illuminates an event marks the event in time. If something can happen and yet leave the light unperturbed, which is the essence of temporal cloaking, then the event can become as invisible ...
Wired News - Jan 4, 2012
Researchers passed a beam of green light down the cable, and had it move through a lens that split the light into two frequencies, one moving slowly and the other faster. As that was happening, they shot a red laser through the beams. ...
BusinessWeek - Jan 4, 2012
4 (Bloomberg) -- By altering the speed of light beams, like those used for data transmission, US military-funded scientists created a hidden pocket in time that one day may be used in computer espionage. Researchers from Cornell University in Ithaca, ...
Register - Jan 5, 2012
“This approach is based on accelerating the front part of a probe light beam and slowing down its rear part to create a well controlled temporal gap – inside which an event occurs – such that the probe beam is not modified in any way by the event,” the ...
National Geographic - Jan 4, 2012
"Imagine that you could divert light in time—slow it down, speed it up—so that you create a gap in the light beam in time," said study co-author and Cornell physicist Alex Gaeta. "In this case, any event that occurs at that instant of time won't lead ...

A ball is trying to pass through a green beam of laser light without being detected. Two short pulses of red laser light change the color of the green light, and since different colors travel at different speeds, a gap is opened in the beam exactly ...
CNN (blog) - Jan 4, 2012
Gaeta and colleagues used devices called "split-time lenses," which slow down part of a light beam and speed up another part to create a gap in the beam that can then be put back together. The beam would not detect an event in that gap, ...
Daily Mail - Jan 6, 2012
The demonstration 'hid' events for 40 trillionths of a second - or 40 picoseconds - by speeding up and slowing down different parts of a light beam. The different parts of the light beam were then put back together, so that any observers could not ...
Discovery News - Jan 4, 2012
First one would see the shorter wavelengths (violet to blue and green), a gap, then the longer wavelengths (yellow to orange and red). Next, by sending the light through another medium that reversed the dispersion and then another time lens, the beam ...
The State Column - Jan 4, 2012
“It may be desirable to cloak the occurrence of an event over a finite time period, and the idea of temporal cloaking has been proposed in which the dispersion of the material is manipulated in time, producing a 'time hole' in the probe beam to hide ...
GlobalPost - Jan 5, 2012
Nature Asia picks up the story to explain that these researchers have been able to speed up and slow down tiny fractions of a probe light beam, which is used to measure events occurring over minute periods of time. The researchers have been able to ...
Toronto Star - Jan 4, 2012
Using a special lens and a beam of light, researchers at Cornell University have figured out how to stop time. Granted, they can only do it in tiny sections of cyberspace – like centimeter-long sections of optical fibre. And it only lasts for even ...
RedOrbit - Jan 5, 2012
The small difference in speed is then emphasized by placing a transparent obstacle in front of the two beams. This obstacle creates a time gap between the blue and red beams as they travel through the optical fiber. But this time gap is just long ...
The Australian - Jan 4, 2012
"If you take part of the light beam and accelerate it, and slow down the other part, it creates a gap and you can go through," he said. The scientists seek to advance the procedure to widen the "time hole", and integrate spatial cloaking with temporal ...
Fudzilla - Jan 6, 2012
The beam then entered a section of cable that had the property of carrying light of different wavelengths at different speeds, specifically blue light faster than red. Then the two colours separated until there was a space between them where there was ...

The experiment involved shooting a beam of light through a device made of a specialized fibre optic glass, called a time lens. Rather than bending the light physically, as normal lenses do, a time lens distorts the light on the temporal scale. ...
Newsbullet - Jan 6, 2012
In temporal cloaking, we accelerate the front part of a light beam and slow down its rear part to create a gap in time,” Fridman said. The Cornell team led by Alexander Gaeta manipulated light using a so-called time lens that enables changes in the ...
ZME Science - Jan 6, 2012
A continuous beam of green light was fired from a laser which became slowed down when it passed through the first half lens, and sped up when it went through the second – a 50 picosecond gap in the beam was thus opened. During this exact window the ...

Cornell scientists explain what they are talking about in this 2011 illustration that shows that if this technique is ever scaled up an art thief can walk into a museum and steal a painting without setting of laser beam alarms or even showing up on ...
Mashable - Jan 6, 2012
You've probably seen fictional cloaks that can make people invisible, but now scientists have created a way to mask whole events in time. A team of researchers at Cornell University have come up with a way to essentially cloak time and space to make a ...

In what may well turn out to be a cracker of a discovery, it has recently been revealed that scientists have made history by marking a breakthrough by inventing a gadget that can make any item invisible, just like the famous mythical cloak in Harry ...
International Business Times - Jan 5, 2012
Unlike visual cloaks that move light away from a source, the scientists created a hole by tinkering with the speed of beams of light. Unlike the blink-of-an-eye experiment, some disappearances of people have left people wondering for decades what ...

Before any bank robbers out there get too excited, it's important to note that the event in question was the passage of a beam of light, and that the researchers only cloaked a section of it for 5 trillionths of a second. ...

We're all probably familiar with the famous story of how United States' cloaking technology was created…but if you're not, allow me to retell it. Way back in the 80′s, right around the time that Michael Jackson was moving from his natural Mocha ...
International Business Times AU - Jan 5, 2012
With the Cornell temporal cloak, the speed of the light beam is altered changing how it interacts with objects. If something can happen that can leave the light undisturbed then the event can become invisible. "You kind of create a hole in time where ...
