During the twentieth century, scientists discovered that the expansion of the universe led to the Big Bang, which meant that it had been smaller, hotter and denser before, quite like a thick soup. Later, when it cooled, it became light and transparent. This light is still flying around in the form of cosmic background radiation, which can be measured, and which has proved that there was evolution before the Big Bang. 

According to the Theory of Cosmic Inflation, a very small region expanded in a short time. This way, it made the universe very smooth and regular, which could then trigger the Big Bang over large regions simultaneously. Another idea claims that the universe goes through cycles of evolution, contracting  and expanding alternatively, thus giving way to the Big Bang.

The String Theory states that both inflationary and cyclic universes are possible, as well as many other types, in fact there is not a universe, but multiverses, one inside another, of different kinds.
