Pentagon, DARPA scientists create ‘time hole’

[beer]

Scientists working in conjunction with the Pentagon have announced the creation of a “time hole.”

A team at Cornell University, working with the support of DARPA, announced Wednesday that they have managed to hide an event for 40 picoseconds (those are trillionths of seconds). The team published the results of the experiment in this week’s edition of the journal Nature.

Scientists said the experiment has yielded results consistent with a phenomenon known as “temporal cloaking,” The experiment is thought to be the first time that scientists have succeeded in masking an event, though research teams have in recent years made remarkable strides in cloaking objects.

Scientists said they were able to achieve temporal cloaking by altering the speed of light beams, similar to those used for data transmission. The scientists said that through the use of various lenses, they shifted the speed of light, causing some beams to travel faster and others slower.

By passing the light through the lenses and then through a medium that dispersed it, the team was able to create a gap in the light — essentially a time when no wavelength was visible. The entire experiment occurred inside a fiber optics cable.

Temporal cloaking, like spatial cloaking, follows all the laws of physics. Cloaking things, either in space or in time, requires the manipulation of light. Light carries information; it bounces off objects, defining their shape and sending those details to detectors such as our eyes. If an object can prevent light from doing that, it will become invisible.

The system, which is the first physical demonstration of a phenomenon originally described theoretically a year ago by Martin McCall and his colleagues at Imperial College London in the Journal of Optics, relies on the ability to use short intense pulses of light to alter the speed of light as it travels through optical materials, in this case an optical fiber.

“We think of time in the way that other people think of space. What other people are doing in space, we can do it in time,” said Moti Fridman, a researcher at the School of Applied and Engineering Physics at Cornell University.

It remains unclear how the experiment’s results will be applied to the surrounding world. DARPA, which receives its funding from the Pentagon, has used the results of a number of experiments in recent years to progress military technology, such as that seen in military drones flying over the skies of Afghanistan.

The team of scientists suggested that the cloaking device could be used for increasing the amount of data transmitted by computers. While the experiment did not yield results anywhere near reliable, the team noted that additional experiments could results in a much longer gap being created.

Probably not viable for human cloaking atm, perhaps steal data from networks without detection?

:think: ?

Wow, where to begin.....

First, it is nice to know that my TAX money is going to worthwhile research....

Now, I am not the sharpest tack in the drawer, but follow me on a couple of points...

1. "Cloaking" or the idea of bending wavforms into non-visible spectra is not new, in fact space is FULL of this phenomena known as DARK MATTER.
   
2. Time, or the concept of time is purely a HUMAN invention, and has no bearing what so ever on events that happen. Its' idea was birthed somewhere around when we first made fire. We need some type of linear tool to measure our own existence, and it seemed like a good idea to use day and night as the first "time" measurements. But to the universe as a whole, our idea of time means...NOTHING.
   
3. The idea of manipulating time as we use it to create a "hole" or "vortex" or any other description you wish to use goes against our linear understanding of the concept, and therefore against our physical laws as we perceive them to be. In other words, the door does NOT swing both ways.
   

I simply cannot believe that the people of this country have become so freakin blind that stupid crap like this is actually believed and tons of money are given to it. Oh wait, what am I saying...these are the same people that invented the "invisible" bomber. :wtf:

1. this is different from dark matter in the sense that dark matter itself cannot be perceived and can never be perceived. The above could temporarily hide any object (the light beams coming from it) allowing for the object to remain in place, but not be (visually) perceived. If the object would be on a pressure sensor then the sensor would show the object as being there the whole time. If some 'security system' would use ultrasonic waves to detect objects in the room, this system would show the object as being there at all time.

2. time is a purely human invention, but they aren't doing anything to 'time'. It might be described as 'temporal cloaking' but in effect it is only 'temporal visual cloaking'. So the temporal doesn't refer to 'cloaking something using/in time', but it refers to the temporal (temporarily hide) nature of the cloaking.

3. slowing down light by no means goes against any physical law.

ps I'm not saying that money should be spent on this research by your government, I'm just saying that the things you stated are incorrect ;)

i see a good budget cut that i would approve of.

Wow. Stumbled into the physics department of nsane. Excuse me while I slowly back away... XDDDD

And the only progress in science for the last 100 years has been thanks to the misuse of military funds in war tech. As much as I like society progressing, I wouldn't do it at the price of a Hiroshima. And let's face it, only after the bomb did we continue to make headway in atomic energy research (i.e. after the military has had the first crack at it, and then been universally canned for it, preventing it from messing with them publicly any further.

Thank you for you guys' input. I have no idea what the hell you guys just said right there, so I will slowly back away now . . .

Ok, it is only because I really enjoy this that I wish to post a response to your well placed rebuttal.

1. Dark Matter has been perceived, in fact the very same scientists that gave you invisible bombers and "temporal" cloaking have measured it as a factor of..mass. In other words, they perceive it to exists, to occupy, and to have some sort of atomic weight. "Dark matter is believed to constitute 83% of the matter in the universe and 23% of the mass-energy."
   
2. I will concede point #2. But I do think that "temporal" is a poor description.
   
3. The speed of light is constant. Unlike the Star Trek show, we do not have the ability to speed up light, nor slow it down. We can refract it, focus it, split it into individual wav forms, (I guess the argument could be made that this process changes the speed of light, but in fact the wav forms speed is constant as well, just occupying a different frequency), transmit it and reassemble it. But lets face it, light is light. Some visible, some not. Speed is constant. Bounce a laser off of a flat surface and it will return in the same amount of time..always. You can change the distance to increase travel time, but light will still travel at the same speed. I am not against research. I would like to see it do better. "The speed of light in vacuum, usually denoted by c, is a physical constant important in many areas of physics. Its value is 299,792,458 meters per second, a figure that is exact since the length of the metre is defined from this constant and the international standard for time. In imperial units this speed is approximately 186,282 miles per second."
