Scientists’ New Time Masker Creates Invisibility
Scientists at Cornell University hid an event for 40 trillionths of a second, according to a study appearing in Thursdayâ€™s edition of the journal Nature. We see events happening as light from them reaches our eyes. Usually itâ€™s a continuous flow of light. In the new research, however, scientists were able to interrupt that flow for just an instant. Other newly created invisibility cloaks fashioned by scientists move the light beams away in the traditional three dimensions. The Cornell team alters not where the light flows but how fast it moves, changing in the dimension of time, not space.
