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

A bold new theory could bridge quantum physics and gravity at last. At Aalto University in Finland, two physicists believe ...

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 ...

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

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 ...

Quantum ideas describe particles and fields in tiny packages, but general relativity paints gravity as smooth curves in space ...

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

General relativity is an astonishingly beautiful theory, and grappling with why it disagrees with quantum mechanics is a joy, ...

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 ...

Since the early days of general relativity ... a special linear case. The field equations then give the correct dynamics for the electromagnetic field. When Albert Einstein formulated his theory ...
