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 ...

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 ...

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 ...

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 ...

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 ...

Theoretical physicist Paul Dirac believed the universe is built using advanced mathematics. He saw this order as the work of ...
