In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here.

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 ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

Tiny little threads whizzing through spacetime and vibrating incessantly: this is roughly how you can imagine the universe, according to string theory. The various vibrations of the threads generate ...

String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a patch of space, the theory says, and you won’t see a menagerie of ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, ...
