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

An experiment has visualized a prediction about objects traveling at the speed of light known as the Penrose-Terrell Effect, first made over 60 years ago. When objects approach the speed of light ...

My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far ...

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 ...

A new experiment has shown what Albert Einstein predicted over 60 years ago — objects moving near light speed appear oddly twisted or flipped. Einstein’s Special Theory of Relativity has long ...

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.

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 ...

Credit: Fug4s/Getty Images In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. Another consequence is ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special ...
