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

Albert Einstein’s statements on philosophy and religion were often memorably resonant. What the great physicist really ...

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

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

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.

When it comes to space travel, Albert Einstein's theory of relativity is a major inconvenience ... across time and space. Back in the real world, wormholes are still theoretical.

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 ...

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 ...

A team of theoretical physicists has proposed a new way to test one of the most intriguing predictions of Einstein's theory of general relativity: gravitational memory. This effect refers to a ...

By modifying Einstein's theory of general relativity, the center of a black hole with infinite curvature could be replaced by a highly curved but regular region of space-time, the researchers ...
