This year is the 100th anniversary of general relativity, or more specifically, the 100th anniversary of the publication of a seminal paper that Albert Einstein wrote on the field equations of general ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

The interior of black holes remains a conundrum for science. In 1916, German physicist Karl Schwarzschild outlined a solution to Albert Einstein's equations of general relativity, in which the center ...

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 ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...
