We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic fabric reveals deeper mysteries about existence, change, and the very nature of ...

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

Einstein’s theory of special relativity tells us that for a moving object, time passes more slowly than for a stationary ...

Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA ...

Ten years after the first gravitational wave detection, a new suite of instruments has captured distinctive ringing signals ...

Around the same time minds were exploding over the wave-particle duality of matter, Albert Einstein was formulating his theory of general relativity, which describes how warping the fabric of space ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...

The merger of two black holes is a momentous event, revealing the wildest and most extreme configurations of space, time and ...
