Time Travel discussion

Hello All
Books like Stephen King's 11/22/63 postulates a scenario where the universe "resists" the past being changed by time travelers, but changing the past is still possible.
What would it be like to travel back in time in a deterministic universe, where the past, present and future are set, and no-one can change anything? Would this automatically mean that nobody has free will?
And what would happen to a time traveler who goes back and knows how the future will play out, yet cannot change anything?

That scenario raises another question: by what right would a time traveler bent into changing history would try such a thing? One individual would want to change the history for everyone, probably to fulfill his own wishes or goals? That's not free will: I would call that hubris and selfishness. I like time travel stories but I prefer when time travel is effected to study history, not undo it. The one kind of intervention I would approve is if someone is trying to avoid a global nuclear war or some other World catastrophe.

Excellent points Michel - there are a few TT books where "rules of TT" are discussed, but I am trying to recall if there are novels where an ethical code of time travel is explicitly presented?

One series of novels on ethical time travel comes to my mind: Time Patrol, by Poul Anderson. They describe the actions of dedicated agents tasked with protecting the integrity of history as we know it now.

Thank you, I will check the series out :-)

My The Loose Ends Saga deals with that ethical issue.

I'll be interviewing Chris about time travel this coming Tuesday, 17 October 2023 at 12 noon New York time. I'll post the link here. In the meantime, here's a trailer for the interview that somehow arrived on YouTube and elsewhere from the future. https://youtube.com/shorts/4G9Nl4gGgg...
