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

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 ...

Mathematical physics is an interdisciplinary field that employs rigorous mathematical methodologies to elucidate and model physical phenomena. It draws upon diverse areas such as differential geometry ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

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

Albert Einstein’s “twin paradox” is a famous counterintuitive implication of the special theory of relativity, but it also reveals deep links between physics and philosophy, as Robert P Crease ...

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 ...

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 ...
