[en] The Newtonian physics is based on absolute time and absolute space, simultaneity is unique and universal. In the Special Relativity the concept of absolute simultaneity is abandoned and time is dependent on the motion state. But both in Newtonian physics and Special Relativity time and space form a rigid background for the dynamics of matter. In General Relativity space and time are incorporated into the dynamics. The geometrical behaviour of bodies and the pace of clocks is dependent on space-time geometry which in turn is influenced by matter. In cosmology this mutual influence is driven to the extreme. Space-time is 'created together with matter'. Geometry is determined by the matter contained in the space. 14 refs., 5 figs. (Author, transl.)
