Traveling at the speed of light challenges the very laws of physics. Discover what happens to time, space, and matter as we approach this cosmic speed limit and why it's still beyond our reach.

The electromagnetic spectrum consists of a group of radiations that all travel at the speed of light (\(3\times 10^{8},m\,s^{-1}\)). In the middle of the EM spectrum is the visible spectrum ...

Researchers have created a compact camera where the lens is replaced by engineered optics that can identify objects at ...

This means that humans could one day be able to travel at the speed of light, a concept that challenges the genius Albert Einstein’s Theory of Relativity. For now, although the theory is purely ...

Astronomers have, for the first time, watched the moment a feeding supermassive black hole at the heart of a distant galaxy spat out a jet of material at one-third of the speed of light.
