hue Gravitons and Extra Dimensions
We're stuck on a membrane of simple 3D, But gravitons drift where we can't ever see.
Fun Fact
Hidden dimensions: String theory suggests there could be up to 7 extra hidden dimensions of space curled up smaller than an atom.
Glossary
string theory (noun)
A mathematical theory in which fundamental particles are represented as tiny, one-dimensional strings. In 1969, Leonard Susskind proposed this framework, modeling gravitons as closed loops vibrating in ten dimensions.
