in the movie:
"If String Theory is correct, the universe possesses nine spatial dimensions and one temporal dimension. Now, we can imagine that in the beginning, all the dimensions were twisted together, and during the Big Bang, three spatial dimensions, the ones that we know as height, width, and depth, and one temporal dimension, what we know as time, were deployed. The other six remained minuscule, wound up together. Now, if we live in a universe of wound dimensions, how do we distinguish between illusion and reality? Time, as we know it, is a dimension we experience only in one direction. But what if one of the additional dimensions wasn't spatial, but temporal?" - Mr. Nobody
the theory:
String Theory, sometimes described as possibly the "theory of everything," began as a way to explain the interactions of particles like protons, but it has developed into one unified theory that relates all fundamental particles and forces. In a nutshell, it describes the universe as being made of one-dimensional strings at its most microscopic level rather than point-like particles. What people identify as particles are actually vibrations in loops of the string, each with its own frequency. They are analogous to the string vibrations on a violin or piano. Instead of producing musical notes, however, each of the preferred mass and force charges are determined by the string's oscillatory pattern. An up-quark is the string vibrating one way, an electron is vibrating the other, and so on.
This theory is called the "theory of everything" because it describes everything in the universe as being made of strings at their most basic level. Because of this, there is a debate saying that it is wrong to thing that everything is just vibrating strings. If this is true, are feeling of sadness, anger, happiness, etc., which are just chemical reactions in the brain, just the result of vibrating strings in our brain?
Prior attempts at relating all aspects of physics have failed to incorporate gravity with their other forces, but String Theory actually requires it. It also requires about six or seven extra dimensions of space, other than height, width, and depth, and relates large extra dimensions to small ones. The study of this theory has also brought about the concept of supersymmetry, which, if it exists, would double the amount of elementary particles.
Researchers are hopeful that String Theory will make predictions sometime in the future that they can experimentally test. It has already had a major influence in mathematics, cosmology, and how particle physicists interpret experiments by offering new approaches and possibilities to examine.
String Theory, if correct, is not going to need any deeper explanation of the universe, rather, it will make the foundation on which people will begin to build their understanding of, well, everything.
