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 ...

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 ...

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

In a recent paper [1], the author shows that in spacetime physics, the Selleri transformations (STs) are viable alternatives ...

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 ...

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 – ...

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

“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 ...
