The very early Universe

We have only vague ideas for the description of the evolution of the very early Universe. The dominating view is that it can be best described by quantum gravitation. There are many good ideas on how to construct such a theory but up to now none of them works completely.

What is meant with the very early Universe? It is the Universe that existed between the time 0 and 10-43s (0.[42 zeros]1). This is an incomprehensibly short time span, but it can be handled in physical theories.

The temperature was also incomprehensibly high in the very early Universe. According to the model it should have been larger than 1032K.

As time went on the temperature decreased, and the evolution of the Universe gradually entered the next stage.
