By taking general relativity into higher dimensions, a trio of physicists has proven that a mathematical pattern of ripples ...

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 ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

(Philipp Tur/iStock/Getty Images Plus) Right on the brink of black hole formation, spacetime can get downright peculiar. This ...

Newton’s law of universal gravitation conceived gravity as a force acting at a distance within an absolute Euclidean space and universal time. This framework was superseded by the geometric paradigm ...

Classical electrodynamics describes the interplay of electric and magnetic fields with charges and currents through Maxwell’s equations. In their covariant form these equations are naturally expressed ...
