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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

A restless state, known as a quantum spin liquid, could unlock new kinds of particles and serve as a foundation for quantum ...
