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 ...

Although Einstein's theories suggest nothing can move faster than the speed of light, two scientists have extended his equations to show what would happen if faster-than-light travel were possible.

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 ...

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 ...

IN an attempt to treat gravitational and electromagnetic phenomena simultaneously within the framework of the special theory of relativity, it has been suggested 1 that the Maxwell-Lorentz equations ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...

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 ...
