The world's first invisibility cloak

Invisibility cloak has long been a dream for the world science community and is a familiar image in science fiction and magic movies. Now, that dream has come true.

A research team from Cornell University, America, successfully built the world's first invisibility cloak, making things invisible not only in space but also in time.

Instead of bending the light to make the object invisible, physicists said the principle of operation was that they slowed down the light and suddenly accelerated it to create a space in which all Things seem to disappear.

However, the current invisibility cloak is only effective in a very short time of one billionth of a second. The researchers said they could make the cloak work for 0.00012 seconds.

Before this cloak, there were many leading inventions such as: in 2009, researchers at Duke University, North Carolina, unveiled a cloak design to hide the turbulence on the flight path, bending the path of microwave. In 2010 British scientists of the University of St. Louis Andrew in Scotland has found a material called 'Metaflex' that makes light move.

In addition, other scientists have found a metamaterial capable of bending light channels and making them invisible in longer waves.
