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 ...

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. Rather than accepting the geometry of space and ...

The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...

A pair of mathematicians have proposed a unified theory of dark matter and dark energy that alters Einstein's equations describing the fundamentals of gravity. They suggest the law of energy and ...

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.

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

There are nuances to particle movement and energy at tiny scales that one of Einstein’s equations did not capture, according to a paper published in Science this week. Researchers were able to measure ...
