We wish to suggest an alternative physical origin and organisation of the universe contrasting with the Standard Model of Cosmology. The masses of Standard Model (SM) particles are generated by interactions between a quantum field, and thermal and particle diffusion waves - the Thermon-PDW mechanism - a process which is observationally confirmed. An exact "ensemble" of quantum fields responding to harmonic solutions of interacting thermal and particle diffusion waves solves the problem of particle mass. However, this generates its own complication: an obligatory requirement for a thermal source perfusing continuously throughout the universe. This constraint (and others) is accommodated by several properties of the principal hypothesis. Furthermore, if this interpretation is validated, it eliminates many difficulties due to the orthodox cosmological model, such as reverse engineering fundamental laws of physics, the initial singularity, initial high temperatures and densities and inflation; generally SMC as a whole should be discarded together with other model possibilities, including string theory solutions, multiverse, quantum loop theories and physics beyond the Standard Model of Particles. The property of primary importance - overwhelming importance - for the new cosmological model is establishing a universe-wide flow of thermal energy, how this is done and its consequences.
