In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Light is part of various disciplines, shaping the world as we know it. In physics, it serves as a measure of speed and makes vision, and the recording of images by the eye and camera lens possible.
