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

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 ...

DURHAM, N.C. – Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter. 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 ...

Brian Greene, a professor of physics and mathematics at Columbia University and director of Columbia’s Center for Theoretical Physics, is the author of “The Elegant Universe” and “Until the End of ...

Recent advances in theoretical physics have highlighted the central role of chaotic dynamics in understanding black hole phenomena and string theory. Chaotic behaviour, characterised by a sensitive ...

At Aalto University in Finland, two physicists believe they may have cracked a puzzle that has defied generations of scientists: how to reconcile the physics of the very big with the physics of the ...

WEST LAFAYETTE, Ind. — A team of Purdue University researchers has been awarded a $1 million W.M. Keck Foundation grant to experimentally test an early prediction originated from string theory: An ...

For decades, scientists have taken issue with “string theory” — a theory of the universe which contends that the fundamental forces and matter of nature can be reduced to tiny one-dimensional ...

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 ...

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