I don't think Carroll can take credit for the idea of the arrow of time being emergent from a local entropy initial state.

Roger Penrose proposed that as far as I know, when Carroll was probably a high schooler.




Explaining an idea is not equivalent to taking credit for it.


> Carroll's argument

This assigns credit to Carroll.


It merely says that Carrol argued. The idea within the argument was no means assigned to her but used to make/support it.


Sean Carroll is a man, and look up the possessive apostrophe while you're at it!


Roger Penrose proposed that as far as I know, when Carroll was probably a high schooler.

No. At least as early as Arthur Eddington when Penrose was a twinkle in his dad's eye.


Thanks didn't know he'd made that argument although I knew he made the connection between entropy increasing and arrow of time.


This idea of time's relation to entropy is pretty iffy. I recommend this book https://news.berkeley.edu/2016/09/20/new-book-links-flow-of-....
