The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

Spacetime isn’t supposed to be predictable, but scientists may have just found the rules ...

Physicists have identified hidden geometric structures in spacetime that remain preserved as it evolves, revealing deep constraints on gravity’s behavior. Drawing on analogies from plasma physics, the ...

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 ...

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

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level the world is bizarrely different than it seems. But, we appear to only have ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test.

Recent theoretical advances have underscored the significance of momentum space geometry in the realm of relativistic physics. Traditional notions of flat momentum space are being re-evaluated in ...
