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

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

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.
