The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of ...

A group of scientists recently revealed the discovery of a new engine capable of exceeding the speed of light with a formula ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

That’s why we enjoyed [Michel van Biezen’s] two part post on how Michelson computed the speed of light in 1927. You can see the videos below. Michelson wasn’t the first, of course.

Quasars are a state when a supermassive black hole at the core of a galaxy is feeding at such a rate that it ends up spewing ...

But we’ll give you the short version here. Light travels about a foot in a nanosecond. What have you got that measures signals on a nanosecond scale pretty reliably? Of course, it’s your ...

In its earliest instants, the universe expanded faster than light (light’s speed limit only applies to things within the universe). That ironed out wrinkles in its early chaotic self and meant ...
