And a sizeable part of the physics and mathematics community is becoming increasingly convinced that string theory may provide the answer. From one principle—that everything at its most ...

Physics has a problem: the rules that govern the cosmos break down when we look inside atoms. This episode explores the quest to unify general relativity with quantum mechanics—two theories that both ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known universe.

This theory is often referred to as a "theory of everything". In particular this theory would unify our understanding of all the fundamental physical forces in our universe. There are four such ...
