The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

The study of Dirac-harmonic maps sits at the intersection of differential geometry and quantum field theory, uniting concepts from harmonic maps and spinor fields into a single elegant framework.

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

From Fundamental Concepts to Dynamical Mechanisms, by Wolfgang Bietenholz and Uwe-Jens Wiese, Cambridge University Press.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

So darkly complex, so fabulously remote from the familiar things of human existence is science’s probing into the fundamental secretae of the universe—of light, electricity, gravity, matter—that the ...
