When the universe was smaller, at the beginning, space was "denser" in effect allowing light to travel much faster, just as sound travels much faster through water than through air. Scientists who ...

Let’s explore how constant this speed of light fundamental constant really is. One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can ...

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...

In Faster Than the Speed of Light: The Story of a Scientific Speculation (Perseus Books), Mr. Magueijo describes how he developed the variable-light theory with a succession of collaborators and how ...

In an industry evolving alongside consumer concerns over rising energy costs, impact on the environment, and, of course, stricter regulations handed down by the government, new technologies are ...

Second, it seems to hold in this concept that if something affects the speed of light, everything else will be affected similarly so that light will always be the fastest thing in any given frame of ...

(via PBS Space Time) One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the speed of light wasn’t different ...
