I guess you will not mind receiving a comment now and then from your old (fiction) posts, since you [ublished a list of them .
I liked your story, but I hope your hero is able to find a new wormhole so as to break out of the trap he is in. Armed with the knowledge of two times/civilizations, it would be fascinating to see how he develops thanks to a third one - of course, if the new wormhole taks him back in time he risks becoming a god.
