Scientists Reflected Electromagnetic Waves in Time — For the First Time

[00:00:00]They managed to reflect the wave not in space, but in time.

[00:00:03]Friends, this is the mid-rate. An experiment that literally turns back time for waves. Subscribe. It's going to get even crazier.

[00:00:11]Scientists from the US have experimentally confirmed for the first time the reflection of electromagnetic waves in time. Something that for more than 50 years existed only in theory.

[00:00:21][music] The breakthrough was made by a team from the CUNY Advanced Science Research Center in New York. The main problem with the theory is the enormous energy consumption. It is necessary to instantly and uniformly change the properties of the medium through which the wave passes.

[00:00:36]The researchers solved this using a meta-material, a metal strip [music] with electronic switches and capacitors.

[00:00:42]At the right moment, they sharply doubled the impedance across the entire structure, creating a so-called temporal boundary. As a result, part of the signal was reflected in time. This is not just a reversal backward. The wave changes its frequency and its end returns first. The signal is literally reversed in time. If you imagine light, its color could suddenly change, say from red to green. Simply put, it's like a temporal mirror. Instead of your face, you would see your own back. The work was published in Nature Psychic and could lead to breakthroughs in [music] wireless communication and energy-efficient wave-based computers.
