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

Tenets of quantum mechanics and special relativity, among other theoretical ideas, lead inexorably to string theory.

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 ...

What is string theory: It replaces point-like particles with tiny vibrating strings, requiring extra dimensions to reconcile gravity with quantum mechanics. Why it matters: String theory could unify ...

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 ...

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 ...

A detailed look at the Universe reveals that it's made of matter and not antimatter, that dark matter and dark energy are required, and that we don't know the origin of any of these mysteries. However ...

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 ...
