# The Strings of Fate (DD-319)

> String theory proposes that particles are tiny vibrating strings. Superstring theories require 10 spacetime dimensions, and M-theory, which links them, requires 11. Beyond the three dimensions of space and one of time, the extra dimensions are thought to be compactified, curled up at scales far too small to detect. String theory remains untested by experiment. The footage is an animated tesseract and other higher-dimensional shapes.

## Quick facts

- **DD-319-F01**: Particles are modeled as strings. _(Write-up · Exhibit A (Strings))_
- **DD-319-F02**: Superstring theory needs 10 dimensions. _(Write-up · Exhibit B (10 dimensions))_

## Write-up

Some versions of string theory need 10 or 11 dimensions. The extra dimensions would be curled up too small to see.

1. **Strings**: Particles are modeled as strings.
2. **10 dimensions**: Superstring theory needs 10 dimensions.
3. **11 dimensions**: M-theory needs 11.
4. **Compactified**: Extra dimensions are curled up.
5. **Untested**: It is not yet tested by experiment.

### Transcript

Did you know? String Theory, particularly in its most advanced forms, proposes that the universe is composed of 11 dimensions. In this framework, the familiar 3 dimensions of space and 1 of time are just the start. The additional 7 dimensions are more abstract and compactified, meaning they are curled up at scales so small that they are imperceptible to our senses and current technology. These extra dimensions are crucial for the mathematics of String Theory. NOW YOU KNOW!
