String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

Knot theory, once a fringe branch of pure math, now drives breakthroughs in physics, DNA research, and quantum computing.

The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery -- and physicists are deeply divided about what is actually going ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

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.
