👉 In quantum mechanics, a "upflicker" is an observable effect that occurs when light or other electromagnetic waves are scattered in multiple directions at the same time. This phenomenon can be observed in various sources, such as laser beams and X-rays. The exact nature of this effect is not fully understood, but it has been extensively studied by physicists since its discovery in the 1960s. The upflicker is named for its resemblance to a flicker or flashing light,
