I enjoyed the article but have a very minor nitpick. I didn't understand why the author added this sentence.

"However, the timescales involved in these calculation are so unreasonably large and abstract that one could wonder if these makes any sense at all."

Apart from the fact that we could wonder about anything and everything I think the author does not state what evidence do we have to suspect that large enough timescales would change the laws of physics.

It could be the case of course, and it would be great to talk about them if they exist but without further justification I feel that this sentence is an unjustified opinion in what is otherwise a very nice article that helps better understand enthropy.
