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

Black holes are usually framed as the ultimate dead ends of the universe, but a new mathematical proposal suggests they might instead be raw material for building shortcuts through spacetime. In this ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery quantum fields that govern particles, and gravity has stubbornly resisted ...

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 ...

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 This framework was superseded by the geometric paradigm ...

Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...

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 ...

This article was originally published by Knowable Magazine. Rod Serling knew all about dimensions. His Twilight Zone was a dimension of imagination, a dimension of sight and sound and mind, a ...
