It is well known that standard Big-Bang cosmology suffers from certain problems, e.g. singularity, horizon, flatness, … In the present work it is claimed that the appearence of some of these problems is due to two main assumptions. The first is the assumption that the 4-dimentional Riemannian (RIE)-geometry gives a complete description of the cosmic space-time. The second is the assumption that the material distribution in the universe is described by a phenomenological (PH)-matter tensor. It is shown that, by relaxing these two assumptions, some of the problems of the standard Big-Bang cosmology could be avoided. The following table summarises some results in favour of the above claim. The absolute parallelism (AP)-geometry is used to construct some of the theories mentioned in the table.
