Answer to Question #37700 in Electricity and Magnetism for mashwood

Question

i am not a physicist. But what if i say BCS theory is wrong!!! what i am trying to suggest here is that as temperature of a superconducting material is made to decrease the vibration of atoms reach an optimum. if the temperature continues to fall, at some point the atoms start to shrink. And after getting to an optimum size they become repulsive to free electrons. So, while the free electrons move through the bulk material, they do not necessarily clash with the lattice vibrations or the atoms themselves.............how is that as a theory????????
