Scientists Confirm the Incredible Existence of Time Reflections

Key Points:
- Scientists have theorized for over 50 years that electromagnetic waves can be reflected temporally, not just spatially, but confirming this phenomenon has been difficult due to the high energy required to create a temporal interface.
- Researchers at the CUNY Advanced Science Research Center in New York City successfully observed time reflections by using a metamaterial strip with electronic switches, allowing them to abruptly change the medium's properties and generate time-reversed electromagnetic signals.
- Time reflection differs from spatial reflection by reversing the signal's frequency and order, meaning a time mirror would show a reversed image, akin to a tape playing backward, and cause colors to shift unpredictably.
- This breakthrough, published in Nature Physics, opens possibilities for enhanced control over electromagnetic waves, potentially improving
