Is this a proof that traveling back in time is impossible?

AI Thread Summary
The discussion centers on the concept of time travel, specifically the notion that the absence of evidence for anyone traveling back in time from the future may suggest that such travel is impossible. It raises the question of whether the ability to travel back in time would imply that the future has already occurred from the perspective of those in the past. Some participants express skepticism about the feasibility of time travel, emphasizing that their beliefs are not based on empirical evidence. The conversation acknowledges the speculative nature of time travel discussions, particularly within the context of science fiction and fantasy. The thread concludes with a lock, indicating no further contributions will be accepted.

Is the fact that no one has ever traveled back in time from the future a proof that traveling back in time is impossible? But if a person can travel back in time doesn't that mean relative to the people in the past the future would seem like it has already happened?

Please provide proof for the statement that no one has ever traveled back in time.

But if a person can travel back in time doesn't that mean relative to the people in the past the future would seem like it has already happened?

That one is too convoluted for me.

I firmly believe that it is impossible to travel backwards in time, but I do not base that on empirical evidence and I am quite sure that neither do you, despite your statement to the contrary.
 
This forum is about science-fiction and fantasy. That is: discussions of a reality in an alternate world. Not speculation about this world.

Saw Mickey 17, a sci-fi comedy, based on Mickey 7, by Edward Ashton, which I read and thoroughly, thoroughly enjoyed. I am fascinated by stories of identity and the meaning of selfness. Mickey Barnes (Robert Pattison - of 'Sparkly Vampire' infamy) is running from a loan shark and, to escape the price on his head, signs up for an off-world trip to a new colony. The only way he could get selected is as an 'Expendable' - which is exactly what it sounds like: he gets all the suicide missions...
So far I've been enjoying the show but I am curious to hear from those a little more knowledgeable of the Dune universe as my knowledge is only of the first Dune book, The 1984 movie, The Sy-fy channel Dune and Children of Dune mini series and the most recent two movies. How much material is it pulling from the Dune books (both the original Frank Herbert and the Brian Herbert books)? If so, what books could fill in some knowledge gaps?
