Researchers at UC Berkeley have successfully built a very, very, very small invisibility cloak. The experiment concealed an object that was about one-thousandth of an inch. It works by affecting how light would typically bounce off a three-dimensional object. Normally light becomes distorted when it does this, but the cloak reroutes the light to make it appear is if it is coming from a two-dimensional object, basically making a flat mirror appear. Even better, they said the cloak could be programmed to match the background behind the object. The cloak is made of an ultra-thin layer of gold blocks that make this magic possible. What's the point of draping yourself in a pimp gold cloak if no one can see it?
It will take time for the researchers to scale up the cloak for larger objects, though they're confident that it's possible. They also noted this technology could have military implications, because they want some of that sweet, sweet military-industrial complex money. So when invisible drones start picking people off from the sky, we'll have these scientists to thank.
