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

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

Albert Einstein is arguably the most influential scientist of the 20th century. His general theory of relativity changed our understanding of space and time, becoming one of the two pillars of ...

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 ...

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 ...

In the quest toward finding the correct theory of quantum gravity, physicists have been testing the holographic principle which, they say, is a key property of any valid theory of quantum gravity.

A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other ...

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 ...

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 ...

Every year, April 18 marks the death anniversary of Albert Einstein ... nuclear energy to GPS technology. Einstein’s Scientific Contributions 1. Theory of Relativity The Special Theory of ...
