The speed of light in a vacuum, clocking in at a showy 299,792,458 meters per second (98,3571,056 feet per second), plays a pretty darn important role in the laws of physics as we understand them – so ...

Faster-than-light (FTL) travel is a concept that has long captivated both the scientific community and science fiction enthusiasts. In a cosmos where light speed is viewed as the ultimate velocity ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

Space — the final frontier. These are the words that introduce every episode of classic "Star Trek," the show that essentially popularized the concept of traveling the stars at the speed of light – or ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. In science fiction, spaceships moving at or beyond lightspeed enable ...

This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first experiment involves measuring the time it takes for light to travel a known ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. The ...

Science fiction authors and readers dream of travelling at the speed of light, but Einstein tells us we can’t. You might think that’s an arbitrary rule, but [FloatHeadPhysics] shows a different way to ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks. When it comes to space travel, Albert Einstein's theory of relativity is a major ...
