Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of 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 ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

Event display in the signal region from data taken in 2018. The pixel tracklet candidate with p T = 1.2 TeV is shown by the red solid line and other inner detector tracks by the thin orange lines.

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...
