…The “dark points” measured by the group are essentially tiny “holes” in the wave structure. Known as vortices, the holes are a common phenomenon in nature: We encounter them in ocean waves, in air currents, and even in coffee when we stir it or pour it into the sink. As early as the 1970s, a surprising theoretical prediction was proposed: Vortices may move faster than the wave in which they are formed. As strange as it sounds—imagine a vortex in a river overtaking the flow of water in which it exists—the phenomenon is real. Until now, this was based on theory. The research team’s achievement has now confirmed it experimentally…
"Our discovery reveals universal laws of nature shared by all types of waves, from sound waves and fluid flows to complex systems such as superconductors. This breakthrough provides us with a powerful technological tool: the ability to map the motion of delicate nanoscale phenomena in materials, revealed through a new method (electron interferometry) that enhances image sharpness.
“We believe these innovative microscopy techniques will enable the study of hidden processes in physics, chemistry, and biology, revealing for the first time how nature behaves in its fastest and most elusive moments.”…
This isn’t even remotely strange, all it requires is precoordinated motion. All it takes is synchronized clocks and you can orchestrate any kind of change in pattern moving faster than light, but it’s nothing but an optic illusion because it’s not self-propagating at light speed.
Yeah it sounds the same phenomenon as if you had 10 bowling balls in a row, and shifted them one foot to the left, then claimed the empty space jumped from the left to the right.
The article doesn’t give much more detail, but I’ll read the actual paper when I’m not on my phone.
