Is Cosmology Still Unmatured?——From the Viewpoint of Scientific Practice

Prof.Tianyu Cao made the conclusion that Cosmology was still not matured through the investigation of existing theory in cosmology.However,when judging the mature level of cosmology,we should not just emphasize on the aspect of theory,by contrast,we should recognize the special characteristic of cosmology which is different from laboratory science just being observed instead of being intervened.It is such feature that makes it difficult to unify various theories of Cosmology.Therefore,the consideration towards mature level of cosmology should pay more attention to the practical rules accumulated in the course of its historical development and to their restrictions to scientific practice.In this regard,Ian Hacking's construction of reasoning styles and the concept of scientific field from Pierre Bourdieu would play an important role in our reflection.
