Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat ...

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

We give a brief survey of the attempts to understand the quantum dynamics of general relativity through the lens of quantum field theory, which has been successfully applied to the other fundamental ...

It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? PBS Space Time is ...

But there is more to string theory than just explaining gravity on a molecular level; string theory is, essentially, the theory of everything. It is the attempt to unite the physics of our universe.

Now there is no doubt that superstring theory, and its successor M-theory, are the dominant paradigms in current attempts to unify gravity and quantum mechanics and to explain all physical phenomena.

A novel theory of 'wavy space-time' suggests that the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

Research The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology. Faculty Research ...

Loop Quantum Gravity. If string theory evaporated tomorrow, something called Loop Quantum Gravity (LQG) would probably be the odds-on favorite to take its place.
