Mastering this will mean the power of god in a limited way, this is much more high-handed than any stealth fighter / ship technologies. This means I whack a missile on you, and no eyes nor radar (similar to light as electromagnetic waves but different frequency) can EVER see.
Because my attack on you is a hidden event in even time itself.:*:
So cool?

Scientists bend time to create invisible light
Esther Inglis-Arkell — Within the tight confines of a fiber-optic cable, some researchers at Cornell have managed to create an invisible flash of light. It's invisible not because the flash is manipulated to be hidden, but because the stretch of time during which it happened is erased by the time the flash gets to the other end of the cable. It has achieved temporal invisibility.
Traditional invisibility cloaks confuse the senses by taking the incoming light from behind an object and reproducing it, perfectly, on the other side. Sometimes the light is recorded and then reproduced. Sometimes the light is bent from the far side to the onlooker's side, around the object. Many of these devices, while not good enough to fool the eye in every situation, are fairly advanced. Cornell researchers have taken a different tack. They've created a set up that erases any visual record of the time when the object blocked out the background.
Their temporal invisibility set-up is rudimentary right now. It's simply the lack of a flash in a fiber-optic cable, but it may represent a new approach to invisibility. Light waves speed down a fiber-optic cable until they hit a time lens. The word 'time lens' sounds awesome, but it has been around for a while. It quickens the transfer of data by staggering the light, speeding some waves up and slowing others down. Between these two, is a little hole of darkness. The hole lasts only 15 trillionths of a second, just enough time for small pulses of light to go down the cable. At the other end of the cable, a lens puts back together the original beam of light, as if the pulses had never been.
This is an early step, and not as impressive as other invisibility cloaks, but it's also a new kind of invisibility. Instead of something interactive, that needs to be bent around an object, the world could be made to be just like a video recording. Snip out the bits that shouldn't be seen and put the tape back together, and it's like nothing was ever there in the first place.

Event cloaks are the sort of thing movies and far-future, ten-tome science fiction tales are made of. That is unless you’re Moti Fridman or part of his group of sharp-minded companions at Cornell, in which case you have designed and built a cloak that hides events in time.
The concept of event cloaking works like this:
Though Fridman and team are deservedly stoked about their design, they are reluctant at this point to discuss applications for it. As of right now, the gap in traffic only lasts 110 nanoseconds. The team claims their limit with this design will be 120 microseconds. That said, this is the first ever functioning cloak, so those numbers could change in the time it takes an event to cross space-time.
For a detailed and considerably more technical explanation of the Cornell team’s research, check out the article at Technology Review.

Metamaterial 'Space-Time Cloak' Conceals Not Just Objects, But Entire Events

The Space-Time Cloak Imperial College London
Forget invisibility cloaks. Researchers at Imperial College London have demonstrated – on paper, anyhow – a metamaterial “space-time cloak” that can conceal entire events from view, making a viewer see one thing while something entirely different takes place behind the cloak. Paging DARPA.
Just as metamaterial “invisibility cloaks” manipulate photons to conceal their subjects or otherwise change visual perception of an object, a space-time cloak would rely on light manipulation to achieve its aims. But unlike other metamaterials, which bend light around an object to render it invisible in certain wavelengths, the space-time material would accelerate and slow photons to create gaps in visual time.
To borrow an analogy from one of the researchers on the project, think of the photons like steady traffic flowing down a freeway. You want to create space to cross the freeway, so you accelerate the traffic. Simultaneously, you slow all the traffic beyond a certain point on the freeway and decelerate all the traffic approaching that point to create a space between the accelerating and decelerating segments of traffic.
Paul Kinsler, Imperial College London
Once you cross, you allow the leading traffic to return to a normal pace and the accelerating traffic to accelerate to catch up to the leading traffic. You’ve just crossed the freeway, but to a person observing the traffic a mile down the road, the gap you’ve created is not visible; the traffic flows by seamlessly.
A space-time cloak would do this with protons, accelerating some, decelerating others, and essentially editing out some in the middle. As such, someone could – and this is an example rather than a suggestion – fool a security camera buy manipulating the photons that reach it. Ostensibly, a safecracker could set up a space-time cloaking device, enter a room, empty the safe, close the door, and make his or her grand escape while a security camera fixed on the safe would see nothing but the closed safe. (You know, like the camera looping scene from Speed, except slightly more believable.)
But the technology doesn’t just serve to enhance the lives of career jewel thieves. This kind of optical manipulation could enhance signal processing and optical computing techniques. And who knows, if someone were to spend some time thinking about it there might be a defense application or two for such technology as well.

The concept of event cloaking works like this:
asically, you need two time-lenses–lenses that can compress and decompress light in time. This is actually possible to do using an electro-optic modulator (what, you don’t have one?). Basically, using two of these modulators you would slow down or compress the light traveling through the first lens, and then set up a second lens downrange from the first that would decompress, or accelerate, the incoming photons from the first lens.
I’m right beside anyone who can’t stand animated gifs, but this one is important so I included it here. Imagine space-time as a constant flow of traffic. Imagine events as chickens who need to cross the road but normally can’t because, you know, constant flow of traffic. But if you take some of those cars (time) and slow them down, you get a gap (hole) that can be crossed by a well-timed chicken (event). To an observer located downstream of the chicken (event) who crossed the road (space-time), no chicken ever existed.
Though Fridman and team are deservedly stoked about their design, they are reluctant at this point to discuss applications for it. As of right now, the gap in traffic only lasts 110 nanoseconds. The team claims their limit with this design will be 120 microseconds. That said, this is the first ever functioning cloak, so those numbers could change in the time it takes an event to cross space-time.
