A series of new animations by a NASA scientist show just how zippy — and also how torturously slow — the speed of light can be. Light speed is the fastest that any material object can travel ...

This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first ...

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 ...

You don't actually understand the speed of ...

Scientists have demonstrated how to manipulate light by using time-varying media in the form of specialized nanomaterials.

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 ...

Researchers at Heriot-Watt University have made a discovery that could pave the way for a transformative era in photonic ...

Light from the Sun reaches Earth through the vacuum of space. The speed of light in air is very close to 300 000 000 m/s. which is nearly a million times faster than the speed of sound ...

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 ...
