problem. So, I cannot give you a satisfactory answer. While cosmology is an interesting field, I believe the existing theories should not be taken too seriously. A reason is that theories in cosmology are often, at best, only speculative in nature. This is also the opinion of Professor C. N. Yang. Nevertheless, if a theory is proven wrong, it is also a progress!
