Visualization of vortices and “dark spots” within a light field — the phenomena measured in new research from the Technion, confirming that they may move faster than the speed of light without violating the theory of relativity. Credit: Nature (2026), DOI: 10.1038/s41586-026-10209-z.

For the first time, “spots of darkness” within light waves — confirming a 50-year-old prediction of faster-than-light motion

A new study from the Technion published in Nature has measured dark spots within light waves for the first time and confirmed that they may move faster than the speed of light without violating relativity.
