| Scientists punch a hole in the fabric of time
 Quote:
"Scientists Punch a Hole in the Fabric of Time with a "Time Cloak""
What a preposterous world we live in, where developments in invisibility cloak tech are common enough to elicit yawns. Fine, you unmovable automatons, how about a time cloak? Is that something you might be interested in?
Researchers at Cornell have designed, built and demonstrated the first "cloak" that hides events in time. The process relies on similar methods of distorting electromagnetic fields as invisibility cloaks, but it exploits a time-space duality in electromagnetic theory: diffraction and dispersion of light in space are mathematically equivalent. Scientists have used this theory to create a "time-lens [that] can, for example, magnify or compress in time."
The time cloak takes two of those lenses and arranges them so that one compresses a beam of light while the other decompresses it. That leaves the beam seemingly unchanged, but the diffraction and dispersion actually "cloak" small events in the beam's timeline. Right now, the cloak can only last for 120 nanoseconds, and the theoretical max for the current design measures just microseconds. But the prospect of being able to exist outside of time, even for just a few microseconds, should be enough to make even the most jaded tech nerd giggle at the possibilities.

So what the news story tells us is that time cloaking is possible because of a kind of duality between space and time in electromagnetic theory. In particular, the diffraction of a beam of light in space is mathematically equivalent to the temporal propagation of light through a dispersive medium. In other words, diffraction and dispersion are symmetric in spacetime.

you can cloak the shit, but then what about the lenses?
two floating lenses isnt conspicuous at all.

who knows what shit will be available 10 years from now | But will it ACTUALLY be ten years from now, or will it only be eight years with the two cloaked years in between? Or maybe those are the two years since you heard about it, and this whole experiment has actually been conducted in the future, two years ago?

If someone gets stabbed in the 120nanoseconds they can cloak an event, does the guy not bleed because it wasn't seen in time?
WTF.
