For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

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

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

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

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

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 ...

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

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

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 ...
