The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at ...

Special relativity inter-relates space and time in such a way that the speed of light is constant, and the theory leads to situations where two observers can disagree over time intervals and distances ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

Researchers at Osaka University demonstrate the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve ...

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 ...

It is one of history’s more irritatingly on-brand coincidences that Albert Einstein was born on Pi Day, as though the universe itself decided that if it was going to manufacture the patron saint of ...

Einstein had promised but later refused to publish this 1912 expository treatise, his earliest known manuscript on special relativity. No original manuscripts survive for the articles of Einstein s ...
