A step toward time travel? Physicists reverse waves in time
Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time reversal' doesn't involve historical travel but reverses a wave's sequence, enabling frequency shifts and precise signal manipulation. This innovative approach, demonstrated through 'time interfaces,' promises significant advancements in communications, imaging, and signal control, pushing the boundaries of physical design.
