String Theory Explained – What is The True Nature of Reality?

Kurzgesagt – In a Nutshell2 minutes read

Humans create stories to explain the universe and refine them over time. Atoms were believed to be the smallest unit until elementary particles were discovered, leading to advancements in technology and accurate predictions.

Insights

  • Humans use stories to understand the universe, constantly revising them;
  • String theory aims to unite forces but needs 10 dimensions and lacks proof, yet aids theoretical physics.
