A general theory of superconductivity based on the pairing of electrons that belong to different electronic bands is presented. These electronic bands arise because of a symmetry breaking at the critical temperature in such a way that one electron sees the other as if its mass would be negative. This symmetry breaking leads also to an energy gap (centered round of the Fermi level) between the coupled electrons. Under the assumption that electric resistance is due to electron-phonon interaction, a general equation from which the fundamental properties of any metallic superconductor can be derived is also presented. In the frame of this theory, the electron-phonon interaction (or electric resistance) is cancelled out by the electron-electron interaction in the super-conducting state. Moreover, the Bardeen-Cooper- Schrieffer (BCS) theory is a particular case of our theory and equations, a matter, which leads to a better overall agreement with experimental data.
