Central to their findings is a phenomenon called dark energy. This was discovered in 1998, when astronomers found that the ...

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 ...

What if the life you did not choose is actually being lived somewhere else? From the Many-Worlds Interpretation of quantum ...

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, ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature's forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics ...

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...

Irrational numbers have underpinned quantum mechanics for a century. Removing them could eliminate its strangest features and ...
