Brian Greene: Making sense of string theory

Making sense of string theory

Physicist Brian Greene explains superstring theory, the idea that minscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.

The universe may hold far more than the three dimensions that people experience daily, with physics suggesting up to ten spatial dimensions. Tiny, curled-up dimensions could be woven into the fabric of space, silently influencing the properties of every particle. Superstring theory proposes that all matter emerges from vibrating filaments of energy, and the geometry of these invisible dimensions might explain the universe’s most fundamental numbers. Experiments at the Large Hadron Collider could soon reveal whether these hidden realms truly exist.
