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

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

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

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 ...

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 ...

One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant ...

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.

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

Scientists from Brazil are challenging the traditional view of universal constants, proposing that only one constant—time itself—is needed to measure relativistic spacetime. The research team argued ...

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 ...
