Scientists demonstrate how they have have created a new invisibility technique that doesnt just cloak an object -- like in Harry Potter books and movies -- but masks an entire event by briefly bending the speed of light around an event. 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. But scientists have made an entire event impossible to see. They have invented a time masker.
Think of it as an art heist that takes place before your eyes and surveillance cameras. You don't see the thief strolling into the museum, taking the painting down or walking away, but he did. It's not just that the thief is invisible -- his whole activity is.
What scientists at Cornell University did was on a much smaller scale, both in terms of events and time. It happened so quickly that it's not even a blink of an eye. Their time cloak lasts an incredibly tiny fraction of a fraction of a second. They hid an event for 40 trillionths of a second, according to a study appearing in Thursday's edition of the journal Nature.
We see events happening as light from them reaches our eyes. Usually it's a continuous flow of light. In the new research, however, scientists were able to interrupt that flow for just an instant.
Other newly created invisibility cloaks fashioned by scientists move the light beams away in the traditional three dimensions. The Cornell team alters not where the light flows but how fast it moves, changing in the dimension of time, not space.

´It´s something that isn´t there, but you can´t see it!´
What a coincidence! I was just talking to someone about this tomorrow.
This next post will disappear.
Now it’s back!

When my mom was a kid, she put a piece of cantaloupe up her nose.
She doesn’t remember *why* but said it was up there for weeks before she finally sneezed it out.
Gross!
Legos and peas were our specialty...and *911* to the pediatrician.
So, you become a “non event” with a probability of zero...
TODHUNTER: Haven't you ever travelled interstellar?
LISTER: No.
TODHUNTER: Oh, you don't feel a thing. The stasis room creates a static field of time. See, just as X-rays can't pass through lead, time cannot penetrate a stasis field. So, although you exist, you no longer exists in time, and for you time itself does not exist. You see, although you're still a mass, you are no longer an event in space-time, you are a non-event mass with a quantum probability of zero.
LISTER: Oh. Simple as that, eh?
Not with my Flying Inman’s decoder ring it’s not!
Last night I saw, upon the stair;
A little man, who wasn’t there.
He wasn’t there, again today;
Oh how I wish, he’d go away.
That is one symmetrical, uh..., kitty!
