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 ...

A series that introduces the differences between the "widely known image" and the "actual person" by comparing multiple materials.The second installment is Albert Einstein.Explosive white hair. The ...

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 ...

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 ...

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 ...

I. Basic Philosophy of the Original Thesis and the Thesis PoemAlbert Einstein's theory of relativity fundamentally changed ...

An international group of scientists has been studying how the structure of the universe has grown over the past 11 billion years. These researchers recently announced findings about how gravity ...

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

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 ...

Earth’s rotation subtly twists the spacetime surrounding it, an effect predicted by Albert Einstein more than a century ago.

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 ...
