In a paper published in the Journal of Optics, McCall said metamaterials made it theoretically possible to manipulate light rays as they enter a material so that some parts speed up and others slow down. This could create "blind spots" in time, masking an event. While the accelerated light arrives at a space before an event has happened, the rest of the light doesn't reach it until after the event.
