Speed of light

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.

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.

The speed of light is like that annoying friend who beats you at every game. What would happen if humans one day surpassed the cosmic speed limit?

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

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.

The answer can give us an indication of where our universe is headed and how it might end.

Two separate teams of scientists have successfully conducted the world's first quantum teleportation outside of a laboratory. While the setup of both tests have variations, the conclusion is essentially the same: quantum teleportation is possible.
