String theory merges two revolutionary theories of modern physics — quantum mechanics and general relativity — into a common framework. Quantum mechanics is very good at explaining what happens when things are very small or light, like molecules, atoms, and subatomic particles. General relativity steps in when things are very large or massive, on the scale of stars, galaxies, and the universe itself. Neither theory has an adequate grasp on the physics of things that are both tiny and massive, like a black hole or the beginning of the universe.

But is String Theory really the final solution for all of physic’s questions? Or is it perhaps an overhyped dead end? Youtube channel and design studio Kurzgesagt probes these questions with their typical distinctive design, color, and storytelling.
