Proposed 15 years ago, the bounded L2 curvature conjecture has finally been proven by a group of researchers. It provides a potentially minimal framework in which it is possible to solve the Einstein ...

Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

From Quanta Magazine (find original story here). In November 1915, in a lecture before the Prussian Academy of Sciences, Albert Einstein described an idea that upended humanity’s view of the universe.

Although Einstein's theories suggest nothing can move faster than the speed of light, two scientists have extended his equations to show what would happen if faster-than-light travel were possible.

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

Our technological capabilities have become astonishing in recent years. And with science and technology working hand in hand, we are reaching a tipping point in society. Einstein’s general theory of ...
