Speed of light

One frequent question I get is whether we can break the light barrier—because unless we can break the light barrier, the distant stars will always be unreachable.

Australian experts have developed new formulas to allow Einstein's theories to work beyond the speed of light.

A team of researchers claim that the speed of light can be manipulated to reach a standstill when two beams of light are tuned to converge at 'exceptional points,' or a single mode of light.

From the past few years, the technique of long exposure photography has become increasingly popular among photographers. Long exposure photography is a

June 03, 2019 Stock photo: There are three physical processes that accelerate particles to near light-speed. Albert Einstein's special theory of relativity states that photons—or particles of light—travel at a constant speed of 670,616,629 miles per hour. As far as we know, nothing can travel faster than this. But across the universe, particles are often accelerated to 99.99 percent the speed of light. Here's three different ways this acceleration can occur, according to NASA…

Companies must have a crisis plan that establishes clear roles, responsibilities, protocol and messaging. Without it, chaos will result.

What is the true speed of light? What does it tell us? Astronomers use light-speed to measure and understand the universe's expansion.

The speed of gravity is taken to be exactly equal to the speed of light. But is that necessarily true? Here's how we know.
