For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

We have reached an extraordinary point in the history of science, for some physicists believe they are now on the verge of having a single theory that will unite all of their science under one ...

A NUMBER of years ago, a general theory of electronic motion in metals was developed by F. Bloch 1 and others, using the methods of quantum mechanics. Many of the results of this general theory ...

Li, S. , Liang, C. and Jin, M. (2025) Precision Limit for Observation: The Bridge for Quantum Classical Transitions. Journal ...

Theoretical physicists have proposed a potential solution to one of the most puzzling problems in modern physics: the black hole singularity paradox. By modifying Einstein's theory of general ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of ...

Like any substance, neutron stars have an equation of state, or more precisely a phase diagram, such as that for water. The properties of a neutron star are determined by quantum chromodynamics ...
