Later we shall see that when the Universe was tiny, the four forces competed strongly and gravity was as dominant as the other three.
I also pointed out that according to our present understanding, these four forces all come into existence from one primordial force that prevailed at the time of the Big Bang. In this context I presented a figure that I reproduce below.
At the beginning of the Universe [read at the beginning of Time], there was only one force, which very quickly became four. Since then, we have been having just these four, and they have influenced the way the Universe expanded and enriched itself, including with the appearance of living matter.
Naturally, the evolution of the Universe, went hand in hand with this one force becoming many. Thus, one could think of several eras, summarised below:
Long periods of time, one always talks of eras. While history and geology have their own eras, where the Universe as a whole is concerned, the important eras/epochs are the ones shown above.
We are now all set to raise the questions that I referred to earlier. There are obviously many questions that could be raised, and here are a few of them:
