A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of Relativity, though world-changing, was not cited. Yet while delivering his ...

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 ...

As internet conspiracy theories go, this one was exceptionally dumb. At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? A ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and acceleration. Initially ridiculed, Einstein developed key concepts after observing a ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window into the universe’s most extreme events. These collisions not only revealed ...
