    Density Entropy
Click For Summary
A black hole of maximal radius is proposed to have the minimal entropy density among physical entities, while a Planck black hole is suggested to possess the maximal entropy density. The discussion highlights that the maximal classical entropy density for black holes is linked to their surface area topology, which can fluctuate due to quantum uncertainty. There is confusion regarding the term "maximal radius," with some participants questioning if it refers to the entire universe or a naked singularity. The conversation also includes light-hearted commentary on the terminology used. Overall, the topic centers on the relationship between black holes and entropy density in the universe.

I believe a black hole of maximal radius has the minimal entropy density of any physical entity. What physical entity has the maximal entropy density?

Perhaps a black hole of minimal radius, like a Planck black hole, has the maximal entropy density of any physical entity. It has the maximal classical entropy density for black holes, and in addition its surface area topology ("entropy") fluctuates with spacetime extremes from quantum uncertainty.
 
I hate to admit it, but I really can't understand the question. What on Earth do you mean by a black hole of 'maximal radius'? That would be the entire Universe.
 
A naked singularity?
