    Scientists observe ‘negative time’ in quantum experiments

    Experimental physicist Daniela Angulo poses with a device in her physics lab at the University of Toronto. Scientists have long known that light can sometimes appear to leave a material before it enters it, but this effect can be interpreted as an illusion caused by how waves are distorted by the material. It has been ignored. Now, through innovative quantum…
