'Floyd at noon' indeed describes a 3D object, yes. Floyd at 1 is a different 3D object, but it is all still Floyd, and the difference in Floyd's locat...
I did misread it, so thanks. I guess I'm not clear on the difference between the two. Both are essentially ontological stances, which is in the end, e...
Time travel under eternalism is simply any non-timelike worldline, and, if you take the SEP definition, any non-straight worldline. The sort of travel...
"To take place, occur" is what I get from a google query. That works fine, since the definition isn't specifically crafted to exclude the undesirables...
Totally agree. My usages of 'happens' for instance, in eternalist context, are logically consistent, and many of yours are not. Perhaps you are trying...
It is not an assumption, but rather an observation that those words can be applied to a block view, and that they don't mean that it is an assumption ...
It's just that every attempt at describing things in eternalist terms still adds references to flow or other implications of a special moment in time....
Alright, but when in a discussion where the implications of a specific theory (or its alternatives) are very relevant, coming into the discussion in i...
Been away a while. Much of the below is yet more repetitious corrections. An I don't understand why you let the interruption halt the discussion. You'...
No, it doesn't. It is kind of like asking what physics has to say about if the sun suddenly wasn't there. Would Earth continue to orbit for 8 minutes ...
There is no 'again'. She's hitting the button for the first and only time, because she's late for a very important appointment (a job interview say) a...
Train has no wheels since relativistic wheels are a whole new problem. So it's sort of a mag-lev situation where the track is there but doesn't touch....
We set the universe to a state where time is truncated by 30 seconds, in 30 seconds. The same state (sort of) is set each time, so a way out of the lo...
The part I said was true under Newtonian physics was the bit about which runner was first observed to finish, which is a function of where the observe...
Things not specified: The starting point is presumed relatively stationary to both finish lines, in a frame we'll call S. OK, the guys with the stop w...
I did it with one time travel event, a scenario you seem to refuse to comment on directly except to say you apparently don't get it. We've not conside...
It makes no difference in the single-travel-event scenario, and 60 posts into this, multiple events remain out of consideration. As I said, you seem t...
This seems contradictory. Robert and Sue are watching Bob get into the time machine. He reaches for the button and Roberta ceases to exist and Sue is ...
This is just a repeat of what was said before, without answering any of the questions. It's always described only from the PoV of Bob. Bob is born 198...
The word you used was 'overwrite'. I've been trying to explore the implications of various models, but perhaps I have it wrong. To quote: So you seem ...
Why would any of that occur? I mean, sure, if one was to travel to 1990, they'd find me there, but without 2024 memories, but why would the teleporter...
I didn't mention 'exact matter'. Perhaps you misread 'exotic'. One can simply google 'exotic matter' for a more specific list. Not really. CTCs are al...
It is a hypothetical object in the domain of science. Can't help it if the fiction folks are the ones that latched onto it. The particle is lumped ont...
There is evidence one way or the other. There is rarely 'proof' of anything. In this case, there are valid non-local interpretations of physics with s...
If the 2024 that doesn't yet include the time traveler is before the 1990 that includes the time traveler, then if would seem a stretch to call what h...
They didn't in the scenario, so nothing to explain. I suppose it depends on which moment on the new timeline is consdiered to be 'the present'. If, sa...
Given physics where there is a timeline that is the original one, that line cannot have a time traveler in it at all. All the copy lines have but the ...
OK, Bob makes the machine and uses it to go from 2024 to a new timeline starting at 1990. Any point on the original timeline before Bob vanishes from ...
Agree that if the people (especially those on the original timeline) fear the readily available devices, they wouldn't get used and the population rem...
Right. Neglected that bit. well, if everybody had one and knew it worked, I suppose they'd all use it and exit any particular timeline. It's sort of l...
You're not reading my comment. I said that by your rules, a person can be in the presence of at most one actual time traveler. We could have a factory...
By your rules, a person can only be in the presence of but one actual time traveler, even if other people on the timeline also remember time traveling...
That part is just you saying it. It could be just as easily said that everybody (including old Bob) in the copy timeline is a copy. The machine could ...
The SEP does consider travel to a parallel timeline (Meiland, 1974 or Deutsch and Lockwood, 1994) to be time travel despite the lack of rigorous simul...
Fiction is just that: Non-evidence, so it doesn't in any way constitute an argument one way or another. Apparently Kirk was also split by the transpor...
I read almost all of the SEP article. Thanks for the link. Didn't know it had a page on the subject. Apparently what I am doing right now does count a...
How is the 2nd clause different from the first? Both just seem to say that you can't travel to your own timeline, which is partly silly because I am d...
The quip was said in the early days of quantum theory when what is now known as the Copenhagen interpretation was 1) pretty much all they had, and 2) ...
OK, should have thought of that. I was kind of thinking photons, which don't interact with their neighbors nearly as significantly as something like a...
The probability of measuring some part of a system can be computed from the wave function. I've not heard the result of that computation being referre...
Not exactly in those words: That says a parallel timeline is needed, created since it doesn't otherwise exist. The 2nd sentence implies the 1990 new t...
No I can't. You won't let me discuss interpretations at all. You said you're creating a new world, not altering the original, in effort to avoid the p...
It sounds like your machine doesn't travel at all then. It manufactures a new world in 2024 that looks like how things were in 1990. It's a new thing,...
Only if it is claimed that they necessarily must be. We're assuming them here to see if it makes time travel possible. It doesn't, but it does remove ...
Great summary, thanks. All packed into less than a minute to boot. The video author seems also to presume presentism, implying that time itself would ...
Well, you said 'for eternity', which implies time. But I agree that there is no meaningful time without change of some sort. You speak of an observer,...
Ah, gotcha, and that made me re-read the way the OP was worded, and I think your take is more correct than the way I saw the question being asked. Try...
I never said anything about imagining. The comment to which you are replying was a reference to your pressumption of presentism. LuckyR seems to presu...
All this is wrong. A point on the rim of a rigid not-slipping wheel IS folling the path of a cycloid (not well depicted in the drawing which shows the...
Recreating a piece of some past state. Indeed, this isn't time travel being described. I can build a new 1928 Studebaker, even giving it the same seri...
