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

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

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

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 – ...
