A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing group of physicists is treating it as a possible glitch report from the fabric ...

Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, scientists have demonstrated time and time again how correct these theories are.

How is it that galaxies merge and collide but the universe is expanding and everything is moving away from everything else? Justin HammersleySterling Heights, Michigan Whether or not galaxies merge ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

File this one under "fun to think about, probably not changing your day job": a new study just dropped that suggests gravity itself might be the smoking gun that our entire universe is one big ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.

Gravitational waves may leave a permanent timing gap in light, revealing how gravity preserves information through a memory effect.

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 ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Are we living in “The Matrix” in real life? In the 1999 science-fiction film, Neo discovers that the universe is a simulation — but one scientist believes that the idea isn’t all fiction. Dr. Melvin ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...
