Scientists have found a way to make objects “invisible,” using nonmetallic materials, since some light from metals is noticeably lost.


On April 30, 2009, scientists developed a cloak that made objects invisible to near-infrared light.


In 2011, researchers at the University of California, Berkeley, announced that a new cloaking system that is effective in visible light was made, using two calcite crystals of specific dimensions. The calcite’s natural bifringence bends light around any solid object placed between them.  


Vladimir Shalaev, a professor of electrical and computer engineering at Purdue, has proposed another design:  a hairbrush-shaped cone, composed of metal needles.  These needles force light to curve around the cone, and, since no light is not reflected off it, everything inside the cone vanishes.

Of course, the military always has secrets.  This, however, was a more scientific approach.


Plus, I never saw a person in camouflage!  Ha, ha!

A UFO was allegedly "seen" near the Denver airport, but some people say it was moving so fast it was practically "invisible."  This article examines such possibilities:
