John McGreevy is Professor of Physics at the University of California, San Diego. He is a theoretical physicist with interests in quantum matter, string theory, and ...

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 ...

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, ...

This article is the first part of a series about quantum field theory published by Quanta Magazine. Other stories in the series can be found here. Over the past century, quantum field theory has ...

Researchers at The University of South Carolina, USC, have proposed that a link between string field theory and quantum mechanics does exist. The link assumes that string field theory is a fully ...

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

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 ...

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 ...

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 ...

Physicists have developed a novel approach to solving one of the most persistent problems in theoretical physics: uniting gravity with the quantum world. In a recent paper published in the journal ...
