Quantum mechanics can also explain the Electromagnetic force. So on the one hand we have quantum mechanics that explains three of the four fundamental forces and on the other the theory of relativity that explains gravity. Einstein worked the rest of his life on a theory that unified the four forces but could never achieve it, the difficulty was great in essence a theory of everything should explain that everything in the universe is made and why it is so. This question was already asked by philosophers like Democritus in the fourth century before our era, he thought that if you divide something in two and then one of its parts you cut it again and so as many times as possible should come a time when you would find an object that you could no longer divide, called that hypothetical object "atom" that means "not …show more content…
The standard model tells us that they are made of other elementary particles, Leptons, Quarks and also Bosons, although the standard model is consistent with the experiments has left several questions unresolved, for example.

Why do forces have certain arbitrary parameters called "constant" and not others?
But above all ...
Where does gravity come from?
It is in this context that string theory arises, in fact they are five theories or five different approaches but basically postulates that subatomic particles are not dots without dimension as conceived by the standard model, but strings of a dimension, their measurement the length of Planck which is the smallest possible distance, in other words, the pixel of the universe. It happens that these strings vibrate and move following different frequencies and patterns, determined by the multidimensional space in which they move; The way in which they vibrate defines what type of particle they form. Just as the vibration of a guitar string defines which defines which notes you listen
