Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

Albert Einstein's theory of General Relativity has led to our discovery of black holes, gravitational lensing, and gravitational waves. However, for about 30 years, scientists wrote the theory off ...

Einstein’s theory of special relativity, which he developed in 1905, describes how the laws of physics are the same for all observers who aren’t accelerating. In a vacuum, the motion of ...

The accelerating expansion of the Universe, first observed in 1998, remains one of the most profound mysteries in modern physics. It challenges long-standing assumptions about the cosmos and has ...

Einstein presented his general theory of relativity at the end of 1915 in a series of lectures in Berlin. But it wasn’t until a solar eclipse in 1919 that everyone took notice.

Records from Albert Einstein's final years are being published as a book around 20 years after their discovery, as ...

To begin to review Einstein’s relativity theory? That process began more than 100 years ago, before the final version of the theory was published. But it is a tall order.

Albert Einstein’s Theory of Relativity is one of the most significant scientific advances of our time. The concept of relativity was not introduced by Einstein, but he was a major contributor with the ...

Yet Einstein had showed in his special theory of relativity (the predecessor to the... 100 years later, Einstein's theory of relativity stands strong Connecticut Post Logo Hearst Newspapers Logo ...

Einstein’s Theory of General Relativity Stands, but Cracks Are Showing. No one knows what happens inside a black hole, but Einstein’s theory of general relativity still explains the phenomena ...
