Abstract
In this paper a case study of an homogeneous and isotropic expanding space-time that expands via expansion of its basic element raises a fundamental distinction between recession movement of matter and space expansion. We prove that observing matter recession at an accelerating rate is not an indication for the acceleration of the universe expansion. More precisely, we show that the observed acceleration in the recession movement of galaxies is naturally due to the space-time deceleration. The case study provides us with a possible space-time with independent movement that might produce the observed behavior of galaxies registered for the redshift z < 0.5 as well as for the redshift z < 0.5. This case study calls into question the recent interpretation of the accelerating recession movement of galaxies as indication for the universe acceleration.
