The establishment of the standard cosmology is not only a great success, but also a greater challenge. It has already revealed the existence of elusive dark matter and dark energy. But it may also imply the existence of deeper unknown unknowns. It is time to scrutinize key ingredients of cosmology, some of them are century old, with state of the art observations and analysis. I will report some recent progresses in these retrospective researches.
