salsero said:Maybe you are referring to the difficulty in explaining superconductivity in high-temperature superconductors by the BCS theory. However, this does not mean that BCS does not explain superconductivity in simple materials.

No, the BCS Theory has been disproven by multiple experiments and is no longer considered a valid explanation for superconductivity.
The BCS Theory was disproven through a series of experiments in the 1980s and 1990s that showed superconductivity can occur in materials that do not follow the assumptions of the BCS Theory. Additionally, advancements in technology allowed for more precise measurements, which also contradicted the predictions of the BCS Theory.
The current understanding of superconductivity is based on the theory of electron-phonon interactions proposed by Alexei Abrikosov, Lev Landau, and Vitaly Ginzburg. This theory explains superconductivity as a result of the interaction between electrons and the vibrations of the crystal lattice in a material.
The BCS Theory was widely accepted because it provided a clear explanation for superconductivity and successfully predicted the behavior of many superconducting materials. It was also supported by mathematical calculations and experiments at the time. However, as technology and experimental techniques advanced, the limitations of the theory became apparent.
The disproval of the BCS Theory has led to a shift in the focus of research towards understanding the true mechanisms of superconductivity. It has also opened up the possibility of discovering new types of superconductors that do not follow the assumptions of the BCS Theory. This has led to exciting developments in the field, such as the discovery of high-temperature superconductors.
