It is similar, and it may simply be a different way of thinking about it. I would still contend that umtilately everything is determined.

This is quite wrong. The entire POINT of the wavefunction is that, mathematically, every option is contained within the formula. When we observe it, ie when two quantum states interact, we experience only one of those possibilities. So, to correct your explanation, there is point AB in which universe A and B co-exist in a single universe. There is decision point C where there is decoherence C, and, after that decoherence, we get a separated world for both A and B. Obviously there will always be before-C in which A and B are AB, but once the decision is made, A and B are mutually inaccessible. You seem to be assuming that "not making decision C" means that new-world B is created, but this is incorrect. "Not making decision C" would actually be one of the possibilities of decision C. So we can rephrase this as having point ABC in which A is making decision with option 1, B is making decision with option 2, and C is not making the decision between option 1 and 2. The act of not making that decision is still a decision, and would split the ABC point into World A, World B, and World C.

---

We do not disaggre in principle, but I would say that in the original state there was a single universe A, and B and C are children of A. Yes, they were A, but that was a single thing; it was not ABC. When B and C came ito existence their histories were the history of A up to the decision point.

I think we're pretty close to agreement, but a few details need ironing out. B and C don't "come into existence" any more than A "comes into existence" because prior to the decision all three were already co-existing. Let's try it this way: You have World A which reaches Decision B, within Decision B are Worlds C, D, and E. Once the decision is made, C, D, and E ALL separate from A, even though they share A as a common history. In a sense, World A doesn't exist exist anymore because World A was a world in which C, D, and E co-existed. After decision B; C, D, and E split, but they don't really "come into existence," they aren't "created," they were already THERE.

I don't mean to be persnickety about this, but the idea that MW "creates new worlds" is one thing that leads laymen to assume that this would violate the conservation of energy. However, if all the worlds are already there and that they're merely separating at decoherence points, then there's no violation.

No. You can't read-- or more likely, choose not to. The statement's only assertion (you can read it, it's still there, unedited) was in regards to interpreting what the poster called free meant.

It could very well be the case that Jack of Hearts is mistaken about interpreting free's input. But you didn't respond to that. In an act of sophistry and belligerence, you asserted that he was 'mistaken.' The other sentences in your post have to be regarded as non-sequitur or taken with the implication that Jack of Hearts was asserting that time did not exist.

... which he didn't. You, PeterL, know nothing of what this poster thinks about time; and he wouldn't bother to discuss it with you, because your constructs are rife with intellectual laziness and ill will. They always have been, which is why these little peck-a-dillos dot your interaction record here:

An ad hominem (Latin for "to the man" or "to the person"[1]), short for argumentum ad hominem, is a general category of fallacies in which a claim or argument is rejected on the basis of some irrelevant fact about the author of or the person presenting the claim or argument.[2] Ad hominem reasoning is normally categorized as an informal fallacy,[3][4][5] more precisely as a genetic fallacy,[6] a subcategory of fallacies of irrelevance.[7]

I know what you mean A, B, and C have the same history, but there was only one, until the decision. I don't disagree, but I don't like saying that 3=1 or other such mathematical oddities.

The conservation of mass and energy are two reasons why many physicists do not accept MWI: SHAZAM! Suddenly there is three times as much mass as there was a while ago. If you are saying that they completely existed before, then the decision was inconsequential.

I don't want to go into it, but I think there is a way around this, and I think that it has already been proposed, but I haven't found the article.

Again, silly PeterL, you know not with what you play. This reader didn't attack your 'argument' or 'conclusion' through any slight on you. There was no claim or conclusion in the realm of ad hominem-- just reasoning structures (that don't pertain to the argument at hand), followed separately by a normative opinion about why Jack of Hearts holds the belief that interacting with you is the virtual equivalent of watching cable news and therefore not worth serious effort.

So you've demonstrated 1) that you don't know what ad hominem is, and 2) a very specific style of communication that approximates being 'discussion' on a superficial level but is in reality just a subversive form of narcissism.

By erroneously claiming that an 'ad hominem' fallacy made Jack of Hearts' reasoning invalid (again, it didn't commentary on you personally followed after and outside of the reasoning structures, pay attention), you've sidestepped any actual dialogue concerning any issue at hand so that you could 'win' the argument. So--

way to pull out the win, buddy.

I agree.

A forward travel through time is what we do by living. Going backward into time doesn't make sense. It would mean there is something to go backward into, but what is that past time but memories? Remembering the past is all the time travel into the past that we would be able to achieve.

agreed another word comes to mind and that is nostalgia. I hear it a lot when people refer to remembering past time.
I think memory is ''remembering what was''. time is different. it is forward because it is updating to go back would suggest time would date as in dated which could not be the case. time updates itself rather debate itself.
human ages as they go through time if they did not that would mean time travelled back. age is the reason why time goes forward.

Aging is a form of entropy, directed change. The idea of time "updating" as you mention, or rather, change updating makes sense. Change doesn't update itself, it is just more change, always forward.

Upon waking this morning it occurred to me that "space-time" is mistakenly considered real, a substitute for the rejected ether. Although in the formulas used in physics containing a t, standing for time, one could put in a negative t to get a backward prediction, this doesn't mean there is something real called time we could move into in any direction we please.

Those formulas only work as models of reality. What is out there for space are energy fields and what represents time is relative change among objects within those fields. What Einstein did was link energy fields with changing frames of reference.

ageing is as a result of time moving forward and updating ie the more we age and the more time we have in fact consumed in terms of changes. it is reflected on us because we humans are evolving around its changes/updating and the way we express the changes is through growing old. time does not add or surplus it moves in a formula of constant but changing/moving forward I think.
if you take the example of the desert and the way the wind builds up streaks or tiny dunes because the movement shifts forward in a constant but updating way because it goes forward then comes back. the desert does not move but the wind does.
the streaks could be compared to ageing and desert to a human who is exposed to time.

I do not believe there is an ether. the reason for that is that I can only believe in what I can perceive see or feel.

I do not understand energy fields and what they are about. space is energetic because of the planets including earth and humans. we are energy and what surrounds us immediately is what activates the energy within us. energy can only work both ways . it need give and take it circular in that sense. energy is activated upon another sourced one. humans are one source of energy light is another.

All of the predictions of relativity, both special and general hold true in Aether Theory, and there are some predictions of Aether that aare true but are not predicted by relativity. The Michelson-Morley experiment was repeated many times, and was found that there is aether drift, but it is different from what the theory predicted. Dayton Miller was one of the more noted people in the field, but there have been others sinece then who have found more evidence for Aether theory.
You might start from this article:

Nearly all physical processes are reversible (I can't recall the one that isn't), and that may indicate that everything is actually reversible. Yes, reversing an atomic process is not the same as sending me back to 20,000 BCE, but the principal is the same.

That "mathematical oddity" is what is within the Schrodinger Wave Equation, so it's not me saying that "3=1," it's the math.

Yes, and those that don't accept it for those reasons are wrong because nothing new is being created. You seem to share this misunderstanding with them. You don't have "three times as much mass," you have a single mass split (to use our example) three ways. I don't know why you say "the decision was inconsequential if they existed before," because even though they existed they couldn't be experienced distinctly until the decision was made. This is Schrodinger's Cat; until we look into the box, the cat is alive AND dead, and our looking eliminates the "and" and splits between one ALIVE world and one DEAD world.

It strongly suggests that there is something wrong with the math.

Sorry, but the problem of Schrodinger's Cat was eliminated by MWI. The cat is alive in some worlds and dead in other worlds, but it is one or the other. There was only one cat, and it was bifurcated, along with the rest of the world. There was one, and now there are two. Our looking doesn't change anything; the cats were dead and alive respectively from the time the box was closed.

Our looking changes how we interact with other quantum entities; even if we assume that there is a dead-cat world and alive-cat world before we look, we don't know what world we're in until we look, so we "experience" the cat as "alive and dead." This is the same thing with particles. When we're not measuring them, they display the quality of existing in all possible states at once. Once we look, they behave like ordinary matter, one thing or another, not everything simultaneously. In Schrodinger's Cat, the cat is like a particle until we look. This is because we ourselves, as quantum entities, become entangled with other quantum entities. So while our observation is not a "cause" of anything (it doesn't affect the cat), it very much affects how we experience the cat. So, while MW has an answer to what's happening with Schrodinger's Cat, I wouldn't say it "eliminates the problem" (if it even ever was a problem, since it was merely meant to illustrate our observations of particle behavior on a macro level).
