Abstract : This paper interprets the phenomenon of high-Tc superconductivity in the oxide, heavy fermion and organic salt superconductors as a coherent spacetime state of electrons in a two-dimensional system of Cooper electron pairs. At a transition temperature the electrical resistance of a substance whose electrons are in a coherent spacetime state can go to zero in two ways, the first is the ordinary BCS case of superconductivity that is associated with the vanishing of the magnitude of the measured resistance, and the second is the case of coherent spacetime superconductivity that is associated with a value of p/2 for the internal phase angle of the resistance and a corresponding zero value for the measured resistance. The superconducting state (T < Tc) of a high-Tc superconductor is described by a completely coherent spacetime state, while the normal state (T > Tc) of a high-Tc superconductor is described by a partially coherent spacetime state. The normalized superconductivity energy gap for high-Tc substances is found to have the value (6/p) (3.52) / (I - 4/3 theta a) where a = relative internal phase angle of the electron-electron acceleration (force) within a Cooper pair of electrons.
