To me, as a completely non-physicist, the only thing that is significant (with regard to the laws of physics) in this theory is that the universe immediately after the big bang (inflation stage) "swelled", and did not expand, and this happened at a rate of much faster than the speed of light! It was as a result of this process that some "bubbles" were formed, in the place of which we now have galaxies and other clusters.

They are the same as the laws of the modern Universe. But some were not able to work at that stage of the development of the Universe. For example, strong, weak interaction, etc., but therefore it is also called the era of the Great Unification, because these forces were combined due to the inability to work and represented some other force.
