The author derives the Friedmann equation for a radiation-dominated universe and proves it to be valid even for the matter-dominated phase. The result is applied to the frequency of 3K-photons, the critical density and the maximum radius of the universe. The dynamics of the expanding universe is modelled with help of Mach's principle in a soapbubble analogy derived from the first law of thermodynamics. [Note: I doubt the scientific value of this paper.]
