A Real Invisibility Cloak

Real Invisibility Cloak

WASHINGTON (AP) -- Scientists say they are a step closer to developing materials that could render people and objects invisible.

Researchers have demonstrated for the first time they were able to cloak three-dimensional objects using artificially engineered materials that redirect light around the objects.

Previously, they only have been able to cloak very thin two-dimensional objects.

The findings, by scientists at the University of California, Berkeley, are to be released later this week in the journals Nature and Science.

The new work moves scientists a step closer to hiding people and objects from visible light, which could have broad applications, including military ones.

People can see objects because they scatter the light that strikes them, reflecting some of it back to the eye.

Cloaking uses materials, known as metamaterials, to deflect radar, light or other waves around an object.

Metamaterials are mixtures of metal and circuit board materials such as ceramic, Teflon or fibre composite.

i saw this on tv this morning and have spent all day trying to imagine what i would do if i could be invisible.

then i thought about how the military would use the new technology, which made me think the world would end, but then i reasoned that somebody could just invent a way to detect invisibility. which would negate any advantages of being invisible. which led me to think that somebody could also probably figure out a way to make previously invisible things visible again.

i didn't do much else today.

Alien Technology coming out bit by bit.Read about the new implants in the brain that are controled by thoughts.One step away from speaking to each other telapathicley.
