Cornell University boffins have designed and built a cloaking device that can cloak events in time.
The device is made possible thanks to the duality between space and time in electromagnetic theory, the scientists were able to use dispersion to make a lens that focuses in time - much like using diffraction to make a lens that focuses light in space.
nvisibility cloaks are the result of physicists' newfound ability to distort electromagnetic fields in extreme ways. The idea is steer light around a volume of space so that anything inside this region is essentially invisible.
