Presently, determining the true cause as to why superconductivity is generated, a new theory has been propounded. Consequently, the present theory gives very clear and complete understanding as to how superconductivity and properties, effects etc. exhibited by superconductors are generated. Presently, it has also been tried to explain as to how currently known some non-superconducting (e.g. ferromagnetic) substances can be made superconducting. Currently, to explain as to how superconductivity and properties, effects etc. exhibited by superconductors are generated, several theories have so far been proposed. For BCS (Bardeen–Cooper–Schrieffer) theory it is claimed that it provides better quantum explanation of superconductivity and accounts very well for all the properties exhibited by the superconductors. This claim is true but if we examine the BCS theory and its rigorous mathematical proofs closely and intently, we find that it is based on such concepts which are practically not possible and contradict two well-observed facts. Further, it gives rise to several very basic and fundamental questions too.
