In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

For the first time, astronomers have directly observed a spinning black hole bending space and time, as predicted in Albert Einstein's theory of general relativity more than a hundred years ago. The ...

Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 ...

A new software package detailed by Chinese scientists promises to tell what time it is on the moon, accounting for effects of ...

Independent researcher and CEO of IDrive Inc., Raghu Kulkarni, has unveiled a groundbreaking framework for understanding the universe: the Selection-Stitch Model (SSM). The model suggests that ...

By studying ripples in space-time, physicists are testing wheather dark energy might stem from hidden dimensions, elusive ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...
