Scientists experimentally confirmed what we’ve known to be true for half a century—darkness can “travel” faster than light.

It may sound like an oxymoron, but inside a beam of light, there is darkness. Certain points within a complex light wave go completely dark, spots where the wave cancels itself out so thoroughly that ...

For the first time, physicists have observed that 'holes' in light can move faster than the light itself. They're known as phase singularities or optical vortices, and since the 1970s, scientists have ...

A historic discovery in wave dynamics opens new doors for quantum information encoding. Albert Einstein famously discovered that nothing with mass, not even supersonic sound, is faster than the speed ...
