On Wednesday, a group of physicists backed up by the Pentagon announced that they have devised a system of “temporary invisibility“, which would return an event undetectable for a tiny fraction of a second.
This is an experimental device that is inspired by research on the famous”invisibility cloak” of Harry Potter, with the difference that an object is hidden in time rather than space. “Our results represent a significant step towards obtaining a full spatio-layer,” says the study, led by Moti Fridman, from Cornell University in New York.
The progress of physical explores how the frequencies of light move at slightly different challenges.
The research is funded in part by DARPA, an agency of the Department of Defense dedicated to developing futuristic technologies that can have military uses.
