For the first time, physicists have directly observed ‘holes’ in light moving faster than the speed of light itself. However, this phenomenon doesn’t break the fundamental rule of relativity that nothing can travel faster than light.
The phenomenon is known as optical vortices or phase singularities, which are essentially “dark holes” formed when a wave twists as it travels. Researchers have predicted that these whirlpools in light could move faster than the surrounding light, but capturing this effect was previously impossible due to its extremely small scales of space and time.
Using advanced electron microscopy techniques, scientists Ido Kaminer and his team successfully recorded the behavior of optical vortices in a two-dimensional material. They observed that as these vortices approached each other, their velocities briefly reached superluminal speeds before annihilating at the “annihilation point”.
This breakthrough provides new insights into the nature of light waves and enables researchers to study hidden processes in physics, chemistry, and biology. The technique developed could also help address limitations in electron microscopy.
Researchers believe that this innovation will reveal how nature behaves in its fastest and most elusive moments, shedding light on universal laws of nature shared by all types of waves.
