Powerful telescopes and huge gravitational wave detectors will test a theory that one man worked out a century ago with a pencil and paper. Albert Einstein’s general theory of relativity remade ...

The study of relativistic effects in gravitational fields remains at the forefront of physics research, refining our comprehension of space‐time and its intricate interplay with matter. Notably, ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

In the beginning of the year 1905, Albert Einstein was an unknown 25-year-old clerk in the Swiss patent office. By the end of the year, he had published four papers of extraordinary importance. His ...
