The third Quantum Gravity conference took place at Penn State University from 21 to 25 July 2025, bringing together ...

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 enough ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

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 available to ...

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

A new study has revealed a novel effect caused by dark photons—hypothetical particles thought to make up a portion of the universe's elusive dark matter. This discovery, made within the framework of ...

Imagine you are sitting in a big symphony hall, and you're listening to an orchestra play for the first time. The orchestra is performing a Violin Concerto by Beethoven. As the soloist runs her hands ...

Quantum mechanics and general relativity are fundamentally incompatible for reasons that relate to views of the world that simply cannot be reconciled. In general relativity, space and time are ...
