Physicists have taken a step that sounds like science fiction: they have coaxed light into behaving as a “supersolid,” a phase of matter that is at once rigid and frictionless. Instead of treating ...

Can darkness really travel faster than light? A surprising new physics experiment suggests it can—at least in a very unusual way. Scientists observed dark regions within light waves moving faster than ...

Getting light deep inside the body has always come with a catch. Tissue scatters and absorbs it, which means doctors and researchers often have to cut into the body or thread in optical fibers to ...

Scientists have traced a 3,000-light-year-long cosmic jet streaming out from the first black hole ever imaged to its likely source point with the help of "significantly enhanced coverage" from the ...

Solids, liquids, and gases are the primary states of matter that most people interact with in daily life. While not as readily occurring, you may even add plasma to the list, considering you can ...
