Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometers thick—over 1,000 times ...

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

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in ...
