In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating ...

There had to be some problem with the experiments measuring the speed, or some special quirk of light that no one had thought of yet. Otherwise it was simply too absurd.

The speed of light is 299,792,458 meters per second and that constant tells ... This constancy was first established in the late 1800’s with the experiments of Albert Michelson and Edward Morley ...

An experiment which appeared to contradict Einstein by showing that particles could travel faster than the speed of light is wrong after all, a rival group of scientists says.

Students Dominik Hornoff and Victoria Helm of TU Wien performed an experiment in which they were able to manufacture a scenario where they could pretend the speed of light was just 6.56 feet (2 ...

To get the speed of light, multiply the wavelength by 2,450,000,000 hertz. (A hertz is a cycle per second; we're calculating meters per second; microwaves operate at 2,450,000,000 hertz). Your ...

Light doesn’t always travel at the speed of light. A new experiment reveals that focusing or manipulating the structure of light pulses reduces their speed, even in vacuum conditions. A paper ...

The Italian professor who led an experiment which initially appeared to challenge one of the fundaments of modern physics by showing particles moving faster than the speed of light, has resigned ...

Some experiments have appeared to play with the speed of light, but these effects are illusory, ... Shockingly, the neutrinos appeared to beat light speed by 60 billionths of a second.

In science fiction, spaceships moving at or beyond lightspeed enable all manner of universal exploration. But in Earth-bound reality, traveling at the speed of light (299,792,458 meters per second ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over ...
