Stealthy thanks to new technology

This technology can be compared to a painting thief operating right in front of people and cameras without anyone knowing. Nobody saw the thief walk leisurely in the museum, remove the painting from the wall and take it away. Nobody sees the thief, nor does everything he does.

>>>Change history with 'time robe'

What scientists at Cornell University (USA) created is comparable to the above, but on a smaller scale, both in terms of events and time. Their time-cloak cloak could only hide the event in an extremely fast time, about 40 billionths of a second, the study published in Nature magazine said.

We can see things thanks to the light shining on things and countering them to the eyes. Usually it is a continuous stream of light. However, Cornell scientists can interrupt this light for a very small time.

New stealth technology not only hides things
but also hide the whole thing that is happening

Other studies of invisibility cloaks often seek to bend light into objects. But the team at Cornell University changed the speed of light, thereby changing the direction of time, not space.

Therefore, an incident could take place right in front of the camera and security laser beams, such as intruders thieves to steal paintings, without being detected.

It is possible to think of this time mask as if scientists have edited or completely erased a certain historical event that occurred in very short time. This is like watching a movie in which you have a scene that you don't know.

Specifically, scientists have created a lens of light and time . Their method is to split the light into two parts, one part is accelerated and the other is slowed down. This created a space to hide the event, Alexander Gaeta, co-author of the study and director of the School of Experimental Physics at Cornell University, explained.

By using optical glasses, time loopholes are created when light travels along fibers that are thinner than a hair. Scientists shot a beam of light out, and with other light beams, they created a time lens that could split the beam into two parts, moving very quickly, and the other moving very slowly.

This is the first time scientists have created a mask to hide an event - this concept has been mentioned in theory by GS. Martin McCall at the Royal College of London.

According to experts, this technology can bring many useful practical applications. For example, a packet of information can be added to a stream of information flowing at high speed without interrupting the flow of information. However, people often assume that this technology will be more abundance for illegal activities, such as enabling the virus to function.
