More than a century later, scientists are still proving Albert Einstein right. The famed physicist’s revolutionary general theory of relativity debuted in 1915, positing that gravity can be ...

The weak-equivalence principle is integral to general relativity, so these test results offer yet more support for a core theory of our universe. In 1916, Albert Einstein dared to declare that Isaac ...

On Wednesday a total solar eclipse will pass over Iceland and other parts of Europe. Conducted on May 29, 1919, the Eddington experiment made the pages of Scientific American that same year. The ...

One of the most basic assumptions of fundamental physics is that the different properties of mass—weight, inertia and gravitation—always remain the same in relation to each other. Without this ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

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 ...

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 ...

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure ...

It is one of history’s more irritatingly on-brand coincidences that Albert Einstein was born on Pi Day, as though the universe itself decided that if it was going to manufacture the patron saint of ...

Truth is relative when it comes to rumors on the internet.

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 ...
