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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you wanted to answer the question of what's truly fundamental in ...

WEST LAFAYETTE, Ind.—Renowned French scientist Alain Aspect, who won the 2022 Nobel Prize for his pathfinding research in quantum physics, will give a lecture on Monday (May 13) at Purdue University ...

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside. “That’s a super hard problem. It’s amazing they were able to,” said Dan ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This ...

At the subatomic level, particles interact not only with one another, but with the quantum fields inherent to space, both owing to the presence of charged sources and also to the quantum vacuum of ...

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 ...

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.

It might be possible, physicists say, but not anytime soon. And there’s no guarantee that we humans will understand the result. By Dennis Overbye Once upon a time, Albert Einstein described scientific ...
