Calabi-Yau Space | Starscape
Isn't this a strange and beautful picture? It looks sort of like a sphere swirling with mobius strips. This is a Calabi-Yau Space, a complex geometrical structure that just may hold the secrets of the universe on its twistng folds.
The overarching project of modern physics is to find a unified theory of nature, one that unites the four basic forces - electromagnetism, the strong and weak nuclear forces and gravity with the zoo of particles and their interactions described by what's known as the standard model of physics. One of the candidates for this vast and subtle task is string theory.
String theory posits that at its most fundamental level the stuff of the universe, quarks and electrons, is composed entirely of tiny 1-dimensional vibrating strings of energy. To harmonize with the largely proven standard model the theory requires the existence of 10, or maybe 11, dimensions, 6 or 7 more beyond the familiar 4, the 3 of space and 1 of time. Well fine, but where are they?
