Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

How do you calculate infinite quantum outcomes? Feynman Diagrams. The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations in ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, ...

Noncommutative Quantum Field Theory represents an ambitious extension of standard quantum field theory that incorporates a fundamental noncommutativity in the structure of spacetime. In these models, ...

What is a quantum field and how does it interact with matter? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Pick up any science fiction book from the 1960s, and you’ll find parallel dimensions explained through magic portals or mysterious machines that work “just because.” Today’s readers want stories that ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...
