Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the ...

In a recent development that has stirred the scientific community, physicists have reported a fascinating observation of light traveling in reverse through a unique material. This extraordinary event ...

Every generation grows up with starships that jump across galaxies in a heartbeat, but the real universe is far less forgiving than the screen. The same physics that lets GPS satellites work and ...

NORFOLK, Va. — A light year is exactly what it sounds like: the distance light travels in one year. If you need to get somewhere quick, you'd want to jump on this train because light travels through ...

We throw around terms like “light year” and “faster than light travel” frequently. But to really understand the scale it helps to feel how fast the speed of light is. The flight simulation video below ...

An international team of physicists has cooked up with a new theory that could allow for objects to travel faster than the speed of light — and while they say it wouldn’t technically violate the laws ...

My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo ...

On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...
