Scientists at the University of Oxford have simulated a way to summon light, seemingly out of thin air. Their work is quite ...

Oxford scientists have simulated light interacting with “empty” space—a strange quantum effect that sounds like science ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Classical physics predicts that light beams pass through each other undisturbed. But quantum mechanics holds that even what ...

Empty spaces in the dark only appear to be complete voids. Even intergalactic space (in the absence of dust particles) has a ...

Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations—virtual photons popping in ...
