The zero-zero component of the Einstein’s equations for gravity with the metric of the expending universe is called the Friedman equation. We use this differential equation to calculate the behavior of the expending space. The equation includes two unknown functions … Continue reading
Hesitating between continuing the expansion and the transition to contraction The curvature of space of the universe is one of the factors that determine the law of its expansion. Data of observations do not contradict the fact that three-dimensional space … Continue reading
The expansion rate of the universe is governed by three major factors: its matter density, the curvature of the three-dimensional space and the density of invisible energy called dark energy of unknown nature. With the expansion, the density of … Continue reading
