Hello Community,
I have a question that I'm struggling to get clarification on and I would greatly appreciate your thoughts.
Big bang theories describe an extremely low thermodynamic entropy (S) state of origin (very ordered).
Question: Is the big bang considered to be a high or low shannon entropy (H -information) state?
Here's why I question:
S and H are related: S = the amount of H needed to define the detailed microscopic state of the system, given its macroscopic description.
Thus: Gain in entropy always means loss of information.
2nd Law of Thermodynamics: S always tends to increase for closed systems.
Therefore: H is generally decreasing.
This suggests a very high Shannon entropy state at the big bang.
However Shannon entropy is very closely connected to the number of degrees of freedom, etc.
i.e Wasn't there a lot less degrees of freedom around the time of the big bang? Also, wasn't the universe a lot smaller and given the max information density, didn't it have a much smaller max H?
This suggests a very low Shannon entropy state at the big bang.
I'm confused, can't find anything on this anywhere and would love some input.
Blessings to you all :)
