Can you describe what it must have been like right after the Big Bang?
Immediately after the Big Bang, the universe was exceedingly tiny, but if we had instruments to detect and magnify the effects of these first moments, we would see the following:
First, assuming that the universe came into existence in a quantum cosmological state with gravity being unified with the other three universal forces (electromagnetic, strong nuclear and weak forces), then what we would have seen first is the separation of gravity from the other three forces.
When this separation occurred, a space-time field similar to the one described by the general theory of relativity (which is still present today) would have emerged to cause gravitational effects (instead of quantum gravity). If we could have seen into the very tiny universe, with a very slow-motion camera (because this was all happening very quickly), we would have seen a glorious, symmetrical transition of physics that is quite indescribable in terms of its complexity, yet simple emergence.
This would have been followed by the separation of the strong nuclear force from the unified electro-weak force, which would have been similarly magnificent, complex and symmetrical. This would have led to an inflationary state where the universe would have expanded from a very tiny size (.0000000000000000000000000000001 cm) to about the size of a marble or larger in a very small fraction of time – far less than a single second.
This would have led eventually to the separation of the weak force from the electromagnetic force, and then to the emergence of quarks, and then to hydrogen and helium nuclei.
From them came stars which produced the other elements. It would have been orderly, complex, symmetrical – and above all, quite magnificent.
