Dynamics of the Universe in the Big Bang Model

At present the Big Bang model does not have any significant flaws.
I would even say that it is confirmed to be true to the same extent
that we know that the Earth revolves around the Sun.
Yakov B. Zel'dovich

There is a saying also that "cosmologists are often mistaken, but never in doubt". The model of the Hot Universe, however, though modified, still lies at the heart of modern cosmology.
