The space expansion physics contains several paradoxes which were clearlydemonstrated by Edward Harrison (1981, 1995, 2000), who emphasized that thecooling of homogeneous hot gas (including photon gas of CBR) in the standardcosmological model based on the violation of energy conservation by theexpanding space. In modern version of SCM the term "space expansion" actuallymeans continuous creation of vacuum, something that leads to conceptualproblems. Recent discussion by Francis, Barnes, James, and Lewis (2007) on thephysical sense of the increasing distance to a receding galaxy without motionof the galaxy is just a particular consequence of the arising paradoxes. Herewe present an analysis of the following conceptual problems of the SCM: theviolation of energy conservation for local comoving volumes, the exactNewtonian form of the Friedmann equation, the absence of an upper limit on thereceding velocity of galaxies which can be greater than the speed of light, andthe presence of the linear Hubble law deeply inside inhomogeneous galaxydistribution. The common cause of these paradoxes is the geometricaldescription of gravity, where there is no a well defined concept of theenergy-momentum tensor for the gravitational field, no energy quanta -gravitons, and no energy-momentum conservation for matter plus gravity becausegravity is not a material field.
