String theory offers a unified framework in which the fundamental constituents of nature are one-dimensional objects whose vibrational modes give rise to particles and forces. By embedding gravity ...

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe, conveyed through the exchange of virtual bosons. In electromagnetism, the ...

String theory seeks to describe fundamental interactions by modelling particles as one-dimensional strings. In efforts to unify quantum mechanics and general relativity, it introduces additional ...

One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from fundamental quantum degrees of freedom to establish a quantum theory of gravity.

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.

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 ...

Quasicrystals, exotic states of matter characterized by an ordered structure with non-repeating spatial patterns, have been the focus of numerous recent physics studies due to their unique ...

A decade ago astrophysicists at the Laser Interferometer Gravitational-Wave Observatory (LIGO), operated by the California Institute of Technology and the Massachusetts Institute of Technology, ...

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 ...

Biological systems are notoriously tough to model, especially when it comes to figuring out the axons, neurons, blood vessels, and other structural components of gray matter, or the tissue that makes ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than others. Reading time 5 minutes For all practical purposes, the Standard ...
