@@neilgerace355 yup 🤘🍻🤘

Wonder-full, indeed. As much more of a philosopher and logician than a physicist (while quite handy with the math and arguments), i am frustrated by the inflexibility, and irresolution, of these sorts of ideas and explanations. Well, first off, there are never any explanations, really. The whole thing starts to sound like a scientific circle of great Egos vying for recognition in an obscurity of meaningless, mind-numbing "gamesmanship". The simplest concept, for me, turns on a simple, obvious reversal of our terms: One is born into a world imbued with "future" possibilities, while all about, in every conceivable corner, crack, and crevice, there exists evidence of a rich, full, resonant "past". (Yes, I know that this thesis is not directly relevant to an "effect to cause'" inversion argument, but the parallels are more in the nature of "substance" in change as a metaphor for "the arrow of time" conventions, etc.) Of course, this notion of a dualism in the very "direction" of the temporal IS THE WORLD, at the quantum level too; but the theorists have other commitments, and are seriously baffled by much of the mathematics that is literally coming apart right before their eyes. They love their "clock" time, but seem to have invested in the rather disturbing misconception that they have, unconsciously, gotten rid of "lived" time. I don't know: Whatever your position, I am giving up on the convoluted rationality that guides a great deal of this sort of theorizing today. ...Regards

So time travel alters the past in a way that preserves the future?

@@HansLemurson That's not exactly what happens in the novel. The future is changed by the past but it is kind of merged. Therefore the time travelers are instructed to keep the changes as small (as local) as possible. Time traveler also is a bit of a stretch since there is no physical time travel. It's only information that can travel. Like memories. Questions are: What is your biggest regret in your life? What if your former self suddenly would know the outcome of a decision that transformed into your biggest regret because it is a memory of the future? Would you like to have a second chance? I don't want to spoil the novel completely so I want to leave it at that. I heartily recommend the novel.

Thanks for the info. Science fiction written by a real scientist! Its now in my must read list.

I think it's the right ansatz, and that the back-and-forward outside physical time should be replaced with something like interference of both timeflows that both happen "simultaneously".

Imagine you shine laser pointer into the sky. It now makes "transactions" with unfathomable amounts of matter even billions of light years away (both in space and time). So I don't find this much more satisfying than the other interpretations.

@@jurajvariny6034 Why is that a problem? Those transactions would happen over billions of years, so locality is still preserved. Or do you dislike the number of transactions? That seems like a weird problem given that all modern physics models involve stupid amounts of interactions. The only change is that the interactions are happening in both temporal directions rather than 'jumping' across large distances.

@@slicedtoad if i understood this interpretation correctly it follows that everything we observe depends not only on backward light cone, but also on forward one. And unless the universe collapses in finite time (does not seem to be the case), our forward light cone can even have infinite time span. I find it hard to wrap my head up around - how present can depend on transactions in future which stretches to infinity.

@@jurajvariny6034 I agree it's weird. But it's an alternative is the Copenhagen interpretation which, to me, is so much worse. The math works and makes sense in QM. Trying to translate the math into understandable concepts and analogies is, as far as I can tell, impossible with the Copenhagen interpretation. "A particle exists in all possible states at once" is a nonsense statement. You can fuzz your brain and pretend it almost makes sense, but you're mostly just lying to yourself. The transactional interpretation requires the strange idea of signals travelling backwards in time. Which is weird. But it's not incomprehensible. The backwards travel is strictly limited in such a way that paradoxes don't arise and that information can't be sent back by an observer. We already think of time as a dimension that we travel in one dimension. Adding the idea that certain things travel in the opposite direction isn't that much of a jump. That's my take, anyway. I'm not a physicist, though.

Because it's baloney, just like the rest.😂

I liked this interpretation too and before I knew about it

Photons don't, but fermionic matter (like electrons and atoms) do have a kind of internal 'clock' related to their spin. However, I agree that at the quantum level there is no real 'distance' and so the 'nonlocal' influences are not really 'action at a distance'.

Entropy drives time forward. Each point in time has sequentially less free energy available to do work. Time isn't simply a necessary dimension for space travel, it is the increasingly diffuse distribution of energy. Time is the evolution of free energy.

@@MichelleHell I had never really considered the relationship between entropy and time to be honst. Thank you for giving me food for thought 💭

@@obsidian9537 oh its absolutely necessary to include entropy because of what it means to travel backwards in time. if you isolate a system like a child's play pin and throw a bunch of blocks on the ground, how would you travel backwards? You'd have to rearrange everything back to how it was before the blocks were thrown around, and that takes energy. To actually travel back in time, one would have to revert every particle to its previous position and energy. This isn't time travel as we think about it in movies because we know it's just another configuration making use of time going forward. This brings into question the notion of time as something that flows and is ridden like a wave. There is no time, just your memory of previous states contrasted with information on new states, plus the cost of changing states. The net cost to changing states is diffusion of energy in the universe. This is where you will understand why time travel back is not possible. How do you revert the state of the universe without expending energy and making it more diffuse? Time is nowhere to be found, just the impracticality of utilizing energy to reverse entropy of the universe. A system can reverse entropy at the cost of the entropy for outside of the system, so maybe time travel can exist for fundamental particles on a very short time scale. But that's a far cry from rearranging every electron in your body and in the world.

@@MichelleHell how can there be no time if you talk about changing states? any kind of change implies the existence of an ordered sequence of states

I love "Primer." I've probably watched two dozen times. I really think I'm close to understanding it.

Primer is just classic "parallel reality" time travel, except with two extra twists 1. the traveler ages the same amount of time he's traveling, 2. the traveler cannot travel to a time before the machine was switched on. Both of those twists are effectively just limitations on the classic "parallel reality" time travel, and also, in Primer, the entire plot is ridiculously convoluted, which perhaps makes the time travel bits more confusing than it really is.

@@therflash Technically, you're right, but I think those "twists" change the "rules" of time travel significantly enough that the result is qualitatively different, and made the resulting movie far more interesting than the typical time travel yarn.

@@waltonsimons12 That is true, but fundamentally, whenever they use the time machine, the timelines split and a parallel timeline is created, which means it was included in the "parallel timeline" type. The extra twists are just limitations on top of the "parallel timeline" trope, there's nothing extra that the Primer timetravel is capable of.

@@therflash Sure, but again, I'm speaking qualitatively. As an analogy, consider rock music. Thrash metal, grindcore, crustpunk, and surf music all fall within the genre of rock music. But surf music is very different from thrash metal, grindcore, or crustpunk. Similarly, I think "Primer" is very different from other stories in the "Parallel Timelines" genre of time travel stories.

Thanks for the comment, 👆✍️write to my trader Jeremy personally for inquiries and investment recommendations regarding crypto

It is impossible to make time travel stories consistent. You can always find a flaw in any plot line containing time travel. The best one can do is to make them funny.

I think the show Dark is even better at presenting these ideas. Incredible German sci fi show I recommend to anyone that enjoys time travel stories l.

The Time Traveler's Wife is full of bootstrap paradoxes. SPOILER ALERT: . . . . . . For example, in the past, the time traveler dictates to his 6 years old future wife a list of 152 dates of his encounters with her, which she writes in a notebook. He'd learned the list by reading & memorizing her notebook. And yet, he often says he can't change history, for example he failed each time he tried to prevent his mother's death. I haven't entirely figured out the rules of time travel in that tv series, but my assumption is that he can change history only in ways that don't change his memory of history, and much of his behavior is predestined. I don't understand how the universe enforces that restriction and the predestination, though. He taught himself the rules of time travel, as he understood them, by tutoring his younger self instead of consulting with physicists, because he expected that if he revealed that he travels in time he would become a lab rat for the rest of his life. There's a scene where he's a passenger in a car driven by his 16 years old future wife, who's driving like a maniac because she "knows" from what he's told her about their future that neither of them can be killed that day. He's alarmed by her driving and warns her that, even though the two of them are invulnerable, people in other cars could be victims of her reckless driving and if that happened she would always regret it. This might be a plot hole, because if that had happened it's hard to believe that he wouldn't have been told about it by his future self or by his "regretful" wife. There's also a scene where he's a passenger in a car traveling at 60 mph and is concerned that if he were to time travel away from that moment he would find himself traveling at 60 mph unprotected by the car... but he ought to know he's invulnerable until he reaches the age of the oldest version of himself that he or his wife have met. Still, despite these plot holes, this tv series has a lot of convoluted time travel interactions that are fun to scrutinize for paradoxes. For example, the real reason he didn't consult with physicists must have been that he'd been told by a future version of himself that he didn't; otherwise he should expect from his memorie of his future self that he's invulnerable to the possibility of becoming a lab rat for the rest of his life... at least up until the age of his oldest self that he ever encountered.

You might be on to something there, Marcus.

However, if you travel back in time, you can break the speed limit of light - It is simple. Travel under speed of light, and go back in time so to arrive before light arrives. Woooh - you break the record and outrace the light!

I think you're right. I have no engineering skills, and I have no idea how it was made, but I had a Kenwood pull out CD player in my truck that was skipping like crazy, and I'd had enough, so I yanked the stereo out of the cradle by the handle and started bashing it off of my dashboard and steering wheel with the intent of completely destroying it. But when I couldn't break it on any of the padded materials I slammed it back into the cradle and it started playing perfectly again, just like they designed it to.

@@srobertweiser I can't tell if you joking or not, but "crazy" (even those obviously temporally inconsistent) things do keep happening in this system. The simplest example would be not being able to find something (like car keys) that you're desperately searching for, only to find it at the place that you've already searched like 100 times before. It happened to me, it's probably happened to 90% of people, but we always do what we tend to do in those situations -- completely ignore it, and just write it off as our own mistake and confusion. Just to make it clear, I am *not* saying that this particular system is a (Matrix-like) *computer* *simulation* . What I do imply, however, is that computation itself (and all of its products, like computers and computer simulations) would not even be possible without this system having something *like* it (discrete, neural-network-like, in particular) at its very foundation. As for more complex examples of "reality glitches" (temporally inconsistent events), this is definitely one of the best that I've ever seen. It doesn't even matter if it's genuine or not, it's still the perfect example of what I'm talking about: ukposts.info/have/v-deo/o3-UgX2NmmuaqKc.html

I didn’t particularly care for the novel. It was really more about “relationships” than about the time travel, and I found the romance smugly anti-romantic. The very best time-travel novel ever written, unlikely ever to be surpassed is the first, H. G. Wells’s “The Time Machine”-brilliant, evocative, haunting. The novel with the most time-travel tropes packed into a single story is probably Isaac Asimov’s “The End of Eternity”.

The Bootstrap Paradox is known in Everyday Life circles as the Mystery of the First Egg. Making an egg is easy. You just need a chicken… which comes from an egg.

Anvils are cast, and casting only required some suitable cohesive foundry sand and an anvil-shaped pattern for the mold carved out of wood - for which one can use flaked flint stone tools - so no anvils, or forged tools requiring an anvil like knives or axes are needed to make an anvil.

@Bassotronics - Actually, I think she's pretty good at explaining physics - which most people (in my experience) mistakenly believe is *_complicated_* - in a way that is more accessible to those who aren't familiar with it. But _complicated_ and _complex_ are not the same thing...at least not in my lexicon. Complicated things are messy, convoluted, highly detailed, but not necessarily incomprehensible or unknowable. Complex things (and here I'm referring to the property of *_complexity_* - as in complex systems) are not merely complicated. A complex system is one whose behavior cannot be modeled by finite algorithms. IOW, you can't just explain it or predict its behavior with simple equations. In that sense, physics isn't complex at all; in fact, physics is the science of simple systems. We can model their behavior with statements like F = ma and E = mc^2. Works great for that stuff. But complex systems - like the human body, or the weather (...or the climate), or human. behavior, or the economy...nope. We can create models, and they're useful for certain purposes, but they have limitations. We can't cure the common cold, or cancer, or prevent arthritis, or aging. In a sense, physicists have taken on the easy stuff...well, OK - maybe it's not the easy stuff, but it's the simple stuff. I'm a physicist and an engineer; the problems I tackle are solvable; the systems I deal with are simple. I would not want to be a medical doctor, or a meteorologist, or a psychologist, or an economist. That's the really complex stuff.
