New research suggests researchers should start by comparing parameters other than time.

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

A physicist proposes that consciousness is the fundamental basis of reality, with matter and spacetime emerging from it.

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 ...

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 ...

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