The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

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.

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...
