At the BIG Bang, the universe expanded from a single point into a sphere of radi

Question

At the BIG Bang, the universe expanded from a single point into a sphere of radius about 5 light years rather quickly. estimate the entropy increase in the universe during this expansion under two different assumptions:

a) First assume that at the Big Bang, the diameter of the universe was 1 meter

b) Now assume that at the big bang, the diameter was zero, ie, the universe was volume-less. How does this demonstrate that we cannot know what the universe was like at the big bang, only what it was like immediately after the big bang?

Explanation / Answer

The Big Bang is a cosmological model of the initial conditions and subsequent development of the universe. It is supported by the most comprehensive and accurate explanations from current scientific evidence and observation.[1][2] As used by cosmologists, the term Big Bang generally refers to the idea that the universe has expanded from a primordial hot and dense initial condition at some finite time in the past, and continues to expand to this day.
