A theory that coherently describes all fundamental forces of nature is often called the Theory of Everything,” Aalto ...

New research challenges the long-accepted notion of singularities in black holes — the point where physics allegedly breaks ...

Einstein’s strangest optical illusion has been captured—thanks to lasers, a cube, and a bit of artistic inspiration.

Fast-moving objects don’t always look the way you’d expect. When something travels near the speed of light, strange things ...

In 1959, physicists James Terrell and Roger Penrose (Nobel laureate in 2020) independently concluded that fast-moving objects should appear rotated. However, this effect has never been demonstrated.

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity ...

Since the early days of general relativity, leading physicists, like Albert Einstein and Erwin Schrödinger, have tried to unify the theory of gravitation and electromagnetism. Many attempts were ...

Over four months, March through June 1905, Albert ... Einstein experienced what he would later call “the most fortunate thought of my life.” He knew that his 1905 special relativity theory ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
