Wait, what?Shadow and BoneA team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical lasers.Conventional knowledge presupposes that if two light beams cross, nothing of note happens. But in an experiment, as detailed in a new paper published in the journal Optica, Brookhaven National Laboratory researcher Raphael Abrahao and his team found something strange: a narrow green laser beam, when shot through a larger blue laser beam…
