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 ...

Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date. Think of a black hole, and you might imagine a literal dark hole, but contrary to ...

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 ...

When you hear the name Einstein, the first thing that usually comes to mind is the theory of relativity.E=mc².Time slows down ...

The celebrated scientist transformed our understanding of space, time and energy but also of imagination, knowledge and life.

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 ...

Einstein proposed his special theory of relativity 120 years ago, and despite numerous attempts to challenge it, the theory still remains intact and valid. It is a simple but powerful concept that ...

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 ...

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 ...

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 ...
