When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer ...

At Aalto University in Finland, two physicists believe they may have cracked a puzzle that has defied generations of ...

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 ...

Machine learning helped show how harnessing the weird effects of Einstein’s special relativity could enable a new kind of ...

Physicists have demonstrated the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp ...

IN an attempt to treat gravitational and electromagnetic phenomena simultaneously within the framework of the special theory of relativity, it has been suggested 1 that the Maxwell-Lorentz ...

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

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

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak ...

This is the central consequence of Albert Einstein's special theory of relativity. The object then has a different length than when it is at rest, and time passes differently for the object than ...
