With each cycle of the Universe evolution of its scale factor.
Scientists of the Department of applied mathematics and theoretical physics, University of Cambridge (UK) described the evolution of the scale factor of the Universe within the concept of a cyclical cosmology.
Physicists have considered the decision of McMaster equations of General relativity that the metric of modern the Universe, but allows clearer comparison with the model of Friedman — Lemaitre —Robertson — Walker, to understand its early evolution.
With each cycle of the Universe evolution of its scale factor, as scientists have found, will increase, with the result that the world is becoming more flat (i.e. Euclidean globally described, and not, for example, Riemann, geometry).
The scale factor is a dimensionless factor in the Friedman equation describing the rate of expansion of the Universe (the Hubble parameter). The multiplier depends on the time, in particular, determines the stage of development of the world.
There are several works in which it is assumed that the development of the Universe is cyclical in nature. For example, in Penrose’s theory separates one era from another Big Bang. This theory has not yet received experimental verification.
