The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

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.

University of Chicago physicist Clay Córdova has been named a recipient of the 2026 New Horizons in Physics Prize for his ...

Before Einstein, before Bohr, there was a Jesuit priest with a telescope and a startlingly modern vision of the universe.

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 ...

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, ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to optimally simulate them on a computer? The answer comes from AI. Quantum field ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always posed a problem. Physics can describe a great deal about the universe ...
