A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

For the last 40 years, a dedicated group of theoretical physicists has been beavering away on an ambitious project to create a quantum theory of gravity and unify the four forces of nature. Using ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

Jason Lotay explains how mathematicians studying special geometries are collaborating with physicists to explore M-theory, an 11-dimensional description of the world that unifies the various string ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

In this paper-covered pamphlet of eighty pages, which is sold for saxpence, Prof. Rice sets forth the doctrine of relativity: and not only this, but also (as prelimiriaries to it) the principles of ...

SOMETHING TELLS ME THAT MY NEW BOOK — Questioning Einstein: Is Relativity Necessary? — is unlikely to be reviewed. So I shall say something about it here. I have been working on it on and off for ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 8 years old. A day or two ago, Sabine ...
