re: #180 The Very Reverend Battleaxe of Knowledge

We think time travel (or travel between parallel universes) is authentically impossible, but in my opinion, the probability that we’re wrong about that is much larger than the ostensibly “possible but unlikely” human-looking aliens.

One of the many things that bothers me about TT is the aging paradox.
Suppose you take something with you to the past. Say, your mom’s locket. You leave it to your great-grandmother, it stays in the family and you receive it in the future. The first weird thing is that this locket has no origin, it just “is”, but that’s not what bothers me (it’s weird, but it’s not “logically contradictory”).

From the moment your great-grandma receives the locket to the moment you get it it is inevitably damaged (scratches, etc. - the usual stuff). Then you take it back and it basically has to go through a new aging cycle. All the old scratches remain and the new ones are added. But it’s supposed to be the same locket in the same state, isn’t it? There aren’t supposed to be “new” cycles - it’s just the same time loop. Yet it cannot be the same time loop because each time the locket receives new wear. Moreover, at some point the locket will simply break. This picture just doesn’t make sense. Yet how can it be excluded if TT is possible?
