The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level ...

Scientists have taken a major step toward probing one of physics’ biggest mysteries—how gravity and quantum mechanics fit ...

Subatomic particles, gravity wells and the beginning of the universe – these are difficult and mysterious concepts that are ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

This article was originally published at The Conversation. The publication contributed the article to Space.com's Expert Voices: Op-Ed & Insights. Time feels like the most basic feature of reality.

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...

The field of quantum deformations explores systematic modifications of classical symmetry algebras that underpin our understanding of spacetime. These deformations introduce a quantum parameter – ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

“As long as they live for long enough, they will always become large cosmological beasts,” says Ricardo Ferreira, a cosmologist at the University of Coimbra in Portugal. He’s not talking about actual ...
