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 ...

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 ...

High-speed beam line. FRIB is already recognized as one of the world’s leading rare isotope accelerators. The facility aims ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks.

Although they travel at the fastest possible speed (the speed of light,) they take a while to get here. The universe is big, so the news is delayed by the vast gulfs of space it has to cross to ...

Taara is a silicon photonic chip, which is a technical way of saying it transmits data through the air using beams of light. The original version of Taara worked, but it had limitations — namely ...

Robert Zubrin's Nuclear Salt Water Rocket (NSWR) design is a rocket that uses known physics and engineering . There are ...

A new method for manufacturing lightsails that can reach up 20% of the speed of light is making the technology look more ...

An international team of scientists led by researchers at the Peking University in China has designed a revolutionary ‘all-optical’ chip that uses light to synchronize the speed of processors ...
