Modern cosmology, based on the existing theoretical physics, combined with astronomical observations and a number of assumptions, formed a relatively complete theoretical system, but it was accompanied by confusion from beginning to end. Singularity, skyrocketing, dark matter, dark energy, etc. are all difficult to solve. Modern theoretical physics has certain limitations. It is questionable to describe the whole universe on the basis of it. At present, the interpretation of observational facts such as cosmological redshift and cosmic background radiation are also seem to be far-fetched. Based on the understanding of the vacuum effect and the fact of the interval effect of the field, an infinite order hierarchical cosmic model is proposed.
