Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

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

As we journey from Newton's laws of gravity to Einstein's groundbreaking theory of relativity, and delve into the enigmatic ...

Add Yahoo as a preferred source to see more of our stories on Google. Most people have never heard of vacuum decay, but if it happened it would be the biggest natural disaster in the universe. Sure, ...

Mind = blown.

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

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

Quantum physics didn’t set out to explain the mind. It set out to explain matter. And yet, the deeper scientists went into ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

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.

Delve into the detail of atomic physics. As the basic units of matter, atoms are the building blocks for everything in the universe. Once thought to be indivisible, we now know they can indeed be ...
