For decades, theoretical physics has struggled to reconcile General Relativity with Quantum Mechanics. The primary obstacle is the assumption that spacetime is a smooth, continuous fabric, which leads ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

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 ...

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 ...

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