The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

This also means that there could be hidden curvatures of space-time or gravitational fields, which could explain a fundamental issue in physics: the hierarchy problem. There are several ongoing ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

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 ...

Some string theorists predict at least 10 dimensions, most of which humans can’t perceive. | Andriy Onufriyenko/Moment/Getty Images Ask someone to name every ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

Moduli spaces form the mathematical framework for categorising the diverse solutions characteristic of string theory, providing a systematic means to parameterise the various vacuum configurations ...

Japanese physicists have created a string theory model that simulates the birth of the universe. In their model, the Big Bang was a "symmetry-breaking event" — a fluctuation that caused three spatial ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively simple question: why? One answer, first sketched a century ago and refined ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...
