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 ...

In a continuous pursuit to understand the fundamental laws that govern the universe, researchers have ventured deep into the realms of string theory, loop quantum gravity, and quantum geometry.

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 ...

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

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.

However, like string theory, loop gravity is still a long way from making concrete predictions about the mass of fundamental particles and the strength of the different interactions between them.

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.

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.

Loop quantum gravity might be thought of as the dark horse in the race for a quantum gravity. Nevertheless, it has some remarkable features. For instance, gravity becomes repulsive at high ...
