A bold new quantum theory of gravity may finally bridge the long-standing rift between Einstein’s general relativity and quantum field theory. This potential "Theory of Everything" could answer some o ...

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 ...

A long-elusive "theory of everything" may finally be within reach as Finnish researchers unveil a new quantum theory of ...

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.

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 ...
