(via Minute Physics) This video is chapter 2 in my series on special relativity, and it covers spacetime diagrams, rotational and translational symmetry of both time and space, how certain ...

We've all heard of relativity, but what is it? How does it relate to light and motion? So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion?

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 special ...

The Terrell-Penrose effect, predicted in 1959, suggests that objects moving at speeds close to that of light appear rotated. This optical illusion results from the combination of relativistic length ...

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in ...

Special relativity is beyond weird. Among its many statements are that moving clocks run slow and that moving rulers shrink. But how are we supposed to make sense of this? When you purchase through ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to a science like physics, theoretical expectations must ...

The Twin Paradox is one of the most fascinating and perplexing concepts in Special Relativity. It involves two twins: one stays on Earth while the other travels through space at near light speed. Upon ...

Albert Einstein’s legendary reputation as history’s greatest theoretical physicist, which National Geographic seeks to mine for humanity in Genius, is due in large part to his theory of relativity — ...

If you’ve ever received a speeding ticket or enjoyed a night watching TGIF in the 1990s, then you can thank Albert Einstein. This week marks a century since the patent clerk-turned-physicist presented ...
