On the Mean Density of Matter in the Universe and Dark Energy

Resumo

On the basis of the special relativity theory (SRT), the mean density of matter in the Universe is calculated with the relativistic kinetic energy of receding galaxies taken into account. Within the framework of the general relativity theory (GRT), we estimate the influence on the mean density of the effect of gravitation. A contradiction between the hypothesis of dark energy and conclusions following from SRT and GRT is noted.
