Fifty-eight years after it first appeared, string theory remains the most popular candidate for the “theory of everything,” the unified mathematical framework for all matter and forces in the universe ...

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 ...

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 is the idea that the building blocks of nature are made up of tiny, one-dimensional strings of energy rather than point particles. According to the theory, these strings vibrate at ...

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?” Hawking, who later became my ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical theories, often unveiling hidden symmetries. Some recent studies have been aimed ...
