At the BIG BANG the universe extended from a single point into a sphere of radius about five light years rather quickly. Approximate the entropy raise in the universe during the expansion under two different assumptions

a) First presume that at the Big Bang the diameter of the universe was one meter.

b) Now presume that at the Big Bang, the diameter was zero that is the universe was volume-less. Explain how does this demonstrate that we cannot know what the universe was like at the Big Bang, merely what is was like immediately after the Big Bang?
