The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

Quantum field dynamics in the presence of cosmic strings explores how one-dimensional topological defects, arising in various grand unified and string-theoretic models, imprint distinctive signatures ...

A new study just added an interesting twist to the complicated history of the physics theory.

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 ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by ...

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle, ...

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, ...

A single electron, carrying one quantum bit of information encoded in its spin, has been physically moved across a string of ...
