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

Their tests spanned the entire life cycle of the collision: inspiral, merger, and ringdown. Remarkably, the constraints were ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Quantum mechanics is very impressive. But an inner voice tells me that it is not yet the real thing. The theory produces a good deal but hardly brings us closer to the secret of the Old One. I am at ...

Mind = blown.

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

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 ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...
