Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and acceleration. Initially ridiculed, Einstein developed key concepts after observing a ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light. Einstein’s theory holds that nothing could move faster than the ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. Thanks to a global network of observatories—called the Laser Interferometer Gravitational-Wave ...

Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...
