Discussing Convergence, Time Leaping and More

This thread is a continuation of a conversation begun by North1085 in the comments section of the Attractor Field page. For the beginning and context, see HERE.


(Please pardon me for overly iterating certain points while explaining. I needed to in order to get my thoughts all in order.)

More on Convergence and World Line Structure

"So, the way I'm understanding this is that the entire Alpha AF results in Okabe ALWAYS dying in 2025 (this is just one specific event that ALWAYS occurs) due to convergence, but something that does happen in the Alpha AF but not all the way from 0-0.99% like the lab being in possession of the IBN 5100 (let's say this occurs between 0.3-0.4 just as an example), D-Mails are able to correct this and ignore the Alpha AF's convergence because it isn't as important to the structure of the universe, while Okabe dying is, because it occurs between 0-0.99%?"

Close but not quite the full answer. I'm also going to start with some things that are not quite the answer to your question, but I need to cover these bases before answering in the next part.

As you know, Okabe was able to get his hands on the IBN5100 in the 0.5710..% world lines. However, his death like you said is determined to happen from 0-0.99….% in 2025 and not before. In fact, the convergence that has a hold on his death in this attractor field is so strong that when SERN tests for the existence of world line convergence after they have captured Okabe and co. in 0.334581% in the short story The Distant Valhalla (Somewhat of a SPOILER, highlight to read) [by shooting at Okabe at close range not a single one of the bullets is able to kill him.]

However, it should be noted that D-Mails are unable to completely "ignore" convergence, strictly speaking. Wherever a D-Mail causes you to shift to, the effect of the D-Mail is part of the convergence of the world line you arrive in. But, D-Mails are capable of causing a big enough change to bring you to a different attractor field altogether. Take for example the D-Mail from the Faris Ending in the visual novel, it would cause a shift to the Omega AF -0.275349% or the D-Mail from the Hyde of the Dark Dimension drama CD, which causes a shift to Gamma 2.615074%. Coincidentally, that D-Mail is enough to avert Okabe dying in 2025, because in the Gamma attractor field he is still alive in 2036, terrorizing Japan as its dictator Hououin Kyouma.

"Does this convergence phenomenon only occur when the events are considered important enough to the Attractor Field (i.e. ALWAYS occurring in this AF)? For events that only occur between 0.1-0.2 or a small amount of world lines like that, convergence wouldn't occur? This also sparks another question of mine, which is: "What are the conditions for convergence to occur - does convergence only occur for events that ALWAYS happen in a specific attractor field (all the way from 0-0.99%), or can convergence occur for events that don't ALWAYS happen but mostly alwayshappen in the AF (0-0.8, for example)?"

Let's review a bit what Suzuha had to say,

S: "The universe is like this piece of yarn.
Countless possible worldlines exist side by side, branching out to infinity.
[…]
"The bundle of worldlines that share a point of convergence is called an attractor field.
[…]
"Attractor fields are superpositioned like this.
In each attractor field, the worldlines converge on a different result.
"They don't interact. Each attractor field is independent of the others.
"Of course, they all diverged from a common point somewhere in the past, and they will all converge again at some point in the future, but that takes many hundreds of years. You can think of the attractor fields as very long worldlines."


So, the way I understand it from the events we see depicted in the original visual novel, attractor fields are like gigantic world lines and the reverse is also true; world lines are like small attractor fields, which is why Mayuri always dies on the evening of the 13th in 0.337187%, even though she dies in multiple ways as Okabe tries to save her and even though the Attractor Field Alpha's world line convergence only demands that she die sometime in August, 2010. So, how does that work?

We know that Okabe's Reading Steiner is only triggered by -and the divergence meter he invented can only measure- changes in the world line fluctuation rate, the divergence, up to the sixth decimal place. Any smaller than ±0.000001% and he won't notice the world shifting lines. What's more if the change is small enough even others can notice the change made. Take for example, the gelbanana experiments and the first "so-and-so is stupid" D-Mails that were sent after they first discovered the PhoneWave was a time machine. More concretely, think of the first D-Mail that Okabe sent when he tried to undo Moeka's D-Mail. Since the D-Mail failed to change Moeka's past actions, Okabe felt no change in the world line, and the divergence meter animation that we the audience see when the world line changes did not play. Also, Kurisu who was helping him, still completely remembered helping him send the mail.
However, that is still going from a world line in which Moeka had not received the D-Mail from Okabe, to one in which she had. -The D-Mail just did not have the effect that Okabe wanted because she had lied to Okabe about what she wanted her D-Mail to change.-

Suzuha says, "Countless possible worldlines exist side by side, branching out to infinity."
So for example, let's say within the measurement of 0.000000% there could be micro world lines like
0.00000099999999999…. and on to infinity%
0.000000009032743028…. and on to infinity%

Confused? Think of 0.337187% again, the world line where Mayuri always dies in the evening of the 13th. However, Okabe time leapt multiple times and she ended up dying in multiple ways. Those are all smaller world lines. Let's indicate them as 0.337187…%.

S: "The bundle of worldlines that share a point of convergence is called an attractor field.
[…]
"[…] we're going to jump to a worldline in Attractor Field Beta."
[…]
"Attractor fields are normally separate, but if we go to the instant they diverge..."
K: "The instant they diverge... is that now?"
S: "I was taught that a major divergence occurs in 2010."


The full bundle of world lines in an attractor field share a point of convergence. The world lines of Attractor Field Alpha are converging to a SERN Dystopia. The world lines of Attractor Field Beta are converging to WWIII. Those I'll term Large Divergence Points/points of convergence.

The attractor fields Alpha and Beta are themselves, on a larger level converging to the world's population being culled to 1 billion. Greater than a Large Divergence Point, let's call that a Major Divergence Point -Thanks to the admin of the now defunct ibm500.net SG wiki for the naming.-

S: "I was taught that a major divergence occurs in 2010."

This would be the Major Divergence Point of the PhoneWave time machine, which Alpha, Beta, Delta, and Epsilon all converged to.

Then there are the world lines from 0.000000% to 0.409…% where Faris's father always lives. Let's call that a Medium Divergence Point.

Under that you could have a Minor Divergence Point,

  • Small Divergence Point
  • Micro Divergence Point
  • Submicro Divergence Point
  • Sub-, sub-, sub-, etc. submicro Divergence Point

Imagine that you are at a café and you are trying to decide if you want to order coffee or tea. There is plenty of tea leaves and coffee beans in stock. There is absolutely no special consequence to your decision. However, at the moment, the world is on a world line where you are supposed to order coffee but you order tea instead. Congrats you just caused the world to change micro world lines. :) This is why even though the world lines demand certain things, it is not pure determinism.

K: "Isn't that determinism?"
S: "Close. This model is a little looser.
"You could say it cherry-picks from the many-worlds interpretation and the Copenhagen interpretation."

If you are aware due to time travel and an ability like Okabe's of the world line/attractor field's convergence restraining you then you can make conscious decisions to try to change things. If you are not aware then the world might be moving and drifting through world lines anyway as the billions of people make their billions of decisions, though it would be very rare that any of those decisions or their butterfly effect would be enough to make a ±0.000001% difference to the divergence rate of where the world is at. -Which is why Okabe never felt his Reading Steiner activate from the time he gained it, which is hinted to be due to a fever in 1999, up until he sent the D-Mail about Kurisu's death.-


In answer to your question, I think that convergence happens at all levels of an attractor field and its world lines. It is just a matter of the more major a divergence point is, in other words the more world lines that in a bundle converge to this outcome, the more drastic the effect of your choices has to be to change to a world line not effected by that particular point of convergence -i.e., either diverging to a different outcome at that point or not leading to that point at all because it already diverged at some earlier point in time-. And, that is why it seems more difficult to escape something that the attractor field is converging to than something that only a portion of its world lines are converging to.

Put another way, the more world lines that converge to an outcome the more difficult it is to reach a different outcome because your actions may just lead to the same overall result with the only difference being the way in which that result is reached, i.e. the different ways that Mayuri dies and the different ways in which the IBN5100 does not reach the lab. The difficulty with changing Mayuri's determined death in August 2010 and Okabe's in 2025 is that they happen on such a macro scale that it is difficult to see what their causes are except that it is the Alpha attractor field.

Note 1: Emphasis on, it is the effect of your choice that needs to be drastic and not so much the choice itself. Example, deleting three chopped up emails about Kurisu dying with future send date time stamps from SERN's database is, depending on one's perspective, arguably less drastic a move than Okabe gutting himself in order to fake Kurisu's death. However, the effects of these choices are equally drastic, causing the world to shift out of an attractor field, because SERN noticing the first D-Mail is the trigger, the cornerstone if you will, for the SERN dystopia to become a reality as the future of the Alpha AF, while Kurisu's death is the trigger or cornerstone for WWIII to occur in the Beta AF.

Note 2:

S: "The bundle of worldlines that share a point of convergence is called an attractor field.
[…]
S: "I was taught that a major divergence occurs in 2010."

So, I have been using both "divergence point" and "point of convergence" interchangably as equal terms that just describe different parts of the same phenomenon while explaining. It should be noted that a point of convergence, where two or more world lines converge to, is simultaneously a point of divergence where other world lines diverge away from them. Even world lines that do converge, diverge immediately after. That's why I'm adopting the term "divergence point".

Take 2000 as an example, in 2000 the Alpha, Beta, Omega, Delta, and Epsilon AFs converged to Y2K not happening, while the Gamma AF diverged to Y2K occurring -At the same time it was probably converging with some other as-yet-unnamed attractor fields in which Y2k also occurred.

More on Time-Leaping

"Time leaping and D-Mails have a different reach which effects how much change can be achieved with them due to world line convergence."
I figured as much, but don't they basically use the same equation? Well, the difference being that you can only leap back to your own body and change events from there, while D-Mails can affect other people's phones (this actually makes me wonder what would happen if you time-leaped back into someone else's body, I wonder if that would work).

Hopefully, what I explained in the above section has helped clear up for you a bit the limitations upon a time-leaper in changing an event, but I'll try to give a more in-depth explanation of time leaping in case it helps. Like you seem to already understand, a time leap does use much of the same mechanics as a D-Mail. In a nutshell, it is sending your compressed memories like you would a D-Mail. Only it makes a phone call that sends signals that cause you to download/remember your future memories instead of sending chunks of text to your phone for you to read.

A time leap phone call can actually be sent to someone else's phone -or your phone can be picked up by someone else-, but the predicted results are disastrous.

K: "If you try sending memories to someone else… umm, how do I put this… there's danger that the electrical signals might be rejected."
[…] "If it just bounces off, that's fine but I'm worried incompatible memory data might do serious damage to the recipient's psyche."

For the sake of making an easy to read diagram, lets pretend that world lines are perfectly straight and lined up side by side. Like this, from what we've been shown so far, successful time leaps are not able to travel very far sideways.

ZKtimeleapdiagram

When time leaping multiple times in 0.337187…% in the original VN and anime, Okabe will always end up in the past of 0.337187…%, so his attempts to save Mayuri are always restricted by the convergence of 0.337187…% for her to die on the evening of the 13th. However, the D-Mail to not stop Suzuha that he sends from 0.337187…% gets received in 0.409431%, which causes the world to shift to that line. This works because not stopping Suzuha counts as a Medium or Minor Divergence Point, where the world can cross from one measurable world line to another with a significant difference in outcome.

As explained before, a D-Mail, depending on the contents and the receiver, can have a small enough effect to not change the measurable world line. If Okabe had sent a "Christina is baka" D-Mail, then he would have still stayed in 0.337187…% with only a grumpy assistant as a change. However, sending a D-Mail to not stop Suzuha from leaving on the 9th caused enough changes from that Medium/Minor Divergence Point onwards that 0.337187% and 0.409431% -and many other world lines- shared, for it to be a difference of considerably greater than ±0.000001% causing the world to change to that different, measurable world line, 0.409431%, which coincidentally determines Mayuri's death to not occur on the 13th.

It was just theoretical, you're restricted to 48 hours of jumping back in time. Just assuming that you could time leap backwards any amount of time possible, consider this: Could Okabe theoretically jump back in time to right before he sent that message that made him jump from Beta to Alpha and not send that message, or would the world lines converge and force him into sending that message? Would he be able to jump Attractor Fields like this?


So, time leaping is restricted by the technology that Kurisu has at the time she makes it in the original VN to 48 hours.

O: "Can't you improve it!?"
K: "Eventually, maybe, but certainly now now.
"I'd need a real laboratory with real equipment. It would be expensive, which means we'd need sponsors.
"And if we go looking, I'm pretty sure SERN would crush us.
"I'd say that's proven by the fact that neither you nor I have leapt here from the far future yet."

If we only look at the evidence that is presented in the original novel then time-leaping always sends you back in time to the same measurable world line that you leaped from. In that case, it would make no difference even if Okabe time-leaped to July 28th, because it would be the July 28th of the Alpha attractor field. The D-Mail that got caught in SERN's database in the Alpha AF was sent from the Beta AF. On July 28th in the Alpha AF, Suzuha crash landed in the Radio Kaikan Building which caused Kurisu to not die, which caused Alpha Okabe to not send a D-Mail at that time. He was then overwritten by Beta (Active) Okabe instead.

So far in the whole Steins;Gate franchise there is only one example -at the beginning of the "Three Contrapasso About The Abduction" story in Steins;Gate: Linear Bounded Phenogram- of a time leap phone call being received outside of the measurable world line that it was sent from, and that is also not only an example of a time leap to another attractor field, but an example of a failed time leap as well.

If I remember correctly, Epsilon Kurisu theorizes that the time leap failed because of the modifications they had made to the PhoneWave. However, this is an incorrect hypothesis that she makes due to lack of information. From Okabe's lack of memories about events in the Epsilon AF, his memories corresponding with the Alpha AF, and the fragments of memories he has but does not understand of his experiences in repeated time leaps in Aug. 13th, 0.337187…%, we know that he time leapt from Alpha, and a time leap is not run through the time leap machine again of the world line where it is received, so any modifications made to the PhoneWave in Epsilon would not matter a jot to it.

So, no, I don't think it would be possible for Okabe to, under most circumstances, change attractor fields (successfully) via a time leap, which is similar to how physical time travel in a time machine seems to always be bound to the attractor field you jump from, even though D-Mails are proven to be easily received across attractor fields. One of the most curious things...


More on Okabe Himself Changing World Lines

Earlier in this conversation I told you, "Also, it should be noted that it is not just Okabe who 'jump[s] from one attractor field to the other' the whole world changes to a different world line in a different attractor field. Okabe is, however, aware of this shift when it occurs unlike others due to his Reading Steiner ability."

This holds true when talking about the world changing from one active world line to the next active world line. However, in the alternative endings in the original visual novel and in the spin-off material, we do see Okabe's memories being sent -due to his Reading Steiner(?)- from an active world line to an inactive one or from an inactive one to another inactive one, when sending D-Mails, etc. Now, inactive world lines are all just "possibilities that exist simultaneously", so as far as the main story and its active world line -currently the Steins Gate- is concerned, this doesn't really matter. -Inactive world lines can effect active ones, but we've only seen that happen via physical time travel, i.e. Suzuha from 0.000000% landing in the active Alpha world lines.-

Why exactly would sending a D-Mail from an active or inactive world line to an(other) inactive world line cause the memories and personality of the Okabe from the world line the D-Mail was sent from to be sent as well is still unclear -to me at least-, but I think, we know it happens even in the main story. Okabe from Beta sent the D-Mail about Kurisu dying, this caused his memories to be sent to the Okabes across all of the Alpha AF, even to the world lines that did not immediately become the new active world line. We know this because -Correct me if I'm remembering wrong.- when Okabe starts drifting through the Alpha world lines, past the Alpha world line he first arrived in, it is clear from what the other labmems say that his self had been talking about his Reading Steiner ability already, or calling Christina a zombie, etc. before his "active" self arrives in that world line. Also, there is the very fact that 0.000000% Okabe and Daru were able to reason that the D-Mail about Kurisu's death was the key to getting out of the Alpha attractor field, which info got passed onto 0.000000% Suzuha, who passed it on to the Active Okabe. 0.000000% Okabe would probably not have be able to reason that out if he did not have the memories of being the Okabe who sent the D-Mail, I believe.


Conversation Between Suzuha, Okabe and Kurisu

I had forgotten about this conversation that Suzuha, Okabe and Kurisu have later in chapter six of the VN, until just before I was about to post this. So, I'll just tack this onto the end. It basically has them discussing quite a few things we have covered.

The Time Leap Machine is complete.
It's 2:30 PM on the 13th, about 20 minutes later than before.
Kurisu walks into the lounge with a satisfied look on her face.
It's just her, me, and Suzuha in the lab. I had Daru and Mayuri head to Radio Kaikan, ostensibly to work on the time machine.
S: "So that's the Time Leap Machine..."
Suzuha gazes at the now-complete machine in awe.
I've already explained to her how time leaping works.
It's as different as can be from Suzuha's time machine, which can physically displace actual bodies.
S: "It makes you remember the future, right? That's pretty interesting."
Suzuha crosses her hands behind her head and looks up at the ceiling.
S: "Intuition... sixth sense... deja vu...
"I wonder if those things are actually you recalling future memories."
"Some of SERN's researchers in my time came up with the theory that memories are a way of sharing information across worldlines.
"Maybe it's similar to that."
K: "I just wish we knew more about Okabe's Reading Steiner thing.
"Is it unique to Okabe? Or does everyone have the potential for it and Okabe's is just stronger by coincidence?"
O: "One thing's for certain. My consciousness leaps to the past along wth my memories."
K: "I still don't understand why that is. It would make more sense if you experienced a change in the present, like you do when we send a D-Mail.
"Does your consciousness depend on your memories?"
S: "The problem is that consciousness doesn't have a form that we can see.
"Same goes for the soul. Those things are still in the realm of religion.
"Even in 2036, the existence of the soul hasn't been proven, and nobody's proven what forms consciousness, either."
K: "I see... that's a little disappointing."
O: "Sending my consciousness back has let me change some future events with more precision than D-Mail, but other events are locked in by convergence."
I can change the method of Mayuri's death, but never the fact that she dies.
S: "That's not how it works.
"The future is always determined."
O: "Then why does the path there change?"
S: "Because the worldline changes.
"When you leap into the past and take different actions from before, divergence changes, if only a little bit.
"In most cases, that fluctuation won't amount to more than 0.000001% on the divergence meter.
"Small changes might not register at all."
"When you change the cause, the effect merely shifts to a separate, already-existing worldline."
"Since those two worldlines are almost exactly the same, you barely feel any difference."
So is that why Reading Steiner didn't react?
S: "It's not like the previous worldline disappears. It keeps existing as another possible worldline."
K: "That's the many-worlds interpretation, right?"
S: "In any case, they're not parallel worlds."
O: "So is the future reconstructed?"
S: "I guess you could say that."
I'm confused again. Maybe it's impossible for me to fully understand the structure of the universe.

I didn't say it was in Beta line, I didn't think it. I said it was an exception in the attractor fields.

But now when you said it, Just because of the events,we can't say that they are not on an attractor field, since a person's death etc. Won't affect fields much, unless it affects wordline greatly. (Like the 3rd world war)

Similiar things can happen in different attractor fields. But the fields are separeted because of other major things.

Also It's okabe who says its Steins Gate timeline. Maybe it's really in the Beta AF,just different from other timelines.


And  just because, steins gate have no AF it does not mean other

IMO, Attractor Field are certain fixated events on a group of worldlines, which stood next to each other, or in divergence number they are grouped closely. The death of a person which is affected by Attractor Field is fixated and cannot be changed unless they escape the attractor field itself, that's why Beta-Future Okabe aimed for the gap between alpha and beta attractor field, where lies a worldline unknown to other as no one ever observe the future of worldlines in that gap, the worldline aimed is SG worldline.

No such thing as exception ever explained in the story.

Anon i think i see the point, it's a difference between our interpretation of the meaning of the divergence number.

To summarize, us we think the divergence number is a physical mesure of the worldline divergence and in consequence the limit between attractor fields isn't necessary at 1.000000% and an attractor field hadn't an extension of 1.000000%.

For exemple we can have alpha AF from 0% (the only value set arbitrary) to 1.04%

Beta AF from 1.05% to 2.19%

Gamma AF from 2.20% to 2.84%

And at worldlines at the frontier of attractor field (in this case all worldlines at 1.04XXXX% and 2.19XXXX%) can share characteristics of both attractor fields.

You think the first digit of the divergence number is the signification of the attractor field but this explanation IMO isn't satisfactionnary because that makes the SG worldline an anomaly unlike our opinion which set it to a frontier. That make it more Astrophysical-friendly.

Can you capitalize I, when you use it to mean, yourself, please :). I normally don't care much, but...

The thing is you think it must be exactly like your opinion in order to make it more Astrophysical-friendly. But Wordlines do not need to be astrophysical-friendly. I mean, Suzuha said it needs to pass "1" to get next wordline and it doesn't really get much explanation later.

Why we we need it to be Astrophysical-friendly? It can be anomaly.

Okay, since we are both talking about opinions lets not get to much detail.

0

Passing 1% is escaping alpha attractor field, not just changing worldline.

And in the story the Steins Gate worldline only known by Beta future Okabe and the others, so in alpha future, they probably didnt know what lies in Beta attractor field and not even know if there was a gap between alpha and beta attractor field.

Why we we need it to be Astrophysical-friendly? It can be anomaly.

Because Steins;Gate is about science. Use science to make an explanation suits better for the universe so yes we need the most scientific answer. They said they must pass 1% because they know it significate huge changes that means another attractor field but like BBHQ said, they probably don't know which worldline exactly after 1% and it's sure they don't know what is the future of this attractor field. The only calculated worldline was the Steins;Gate one by beta Okabe.

0

Why I'm against his statement about SG worldline being an anomaly, is because Beta future Okabe found out a way to create a cause that will lead the world to a different future than Alpha and Beta Attractor Fields but the resulting of that change will still be the same at the Turning Point so there is no convergence happening.

Okabe in 21/8/2010 traveled back in time to 28/7/2010 must save Kurisu and somehow destroy the time machine paper nakabachi will bring to russia, but he must deceive his past 28/7/2010 self to see Kurisu lying unconscious on a pool of blood and make his past self thinks that Kurisu died, and by doing so his experience from sending the very first D-Mail until the moment he entered Beta Worldline and then traveled back in time trying to save Kurisu won't be undone.

Okabe can't deny his past experience. If he tried to save Kurisu by different approach, that is where the convergence will happen. Because Okabe himself already saw Kurisu "died", no matter what he did, convergence will make his past self saw her "dead". Making a Casual Loop, in which 21/8/2010-Okabe makes 28/7/2010-Okabe experience the same event like he already had, while preventing direct Grandfather Paradox in which Okabe denies what he already saw in 28/7/2010 and erasing the cause of his whole experience that makes him wanted to save Kurisu so badly.

With that in mind, the result, Okabe in 28/7/2010 saw Kurisu unconscious on a pool of blood, still the same, but the effect it took creates a different future than Alpha worldlines and Beta worldlines, a worldline not within range of both Attractor Fields.

Exactly, S;G worldline shouldn't be an anomaly, define it to be a frontier is far better than an anomaly.

I've always interpretted it as steis gate  being a wordline BETWEEN two attractor fields, as in not influenced by either of them. 

As we see, worldines exist next to each other as possibilities, with 99,99% converging on some attractor field

The difference is i See people thinking that steins gate is influenced by BOTH attractor fields, but that doesnt make sense to me. Attrator field alpha, sern discovers okabes first D mail, attractor field betha, thesis sparks world war 3, two completely seperate events. 


So i dont think that its "because both attractor fields influence steins gate, that neither happens, its the oposite. Because stein gate is EXACTLY between two attractor fields, NEITHER ONE affects it. Allowing an entierly new future, that has been observed by anyone. 

The worldlline okabe inventted the meter wasnt 0.0000, it was just the worlddine okabe originaly invented the meter, taking that as its zero point. But the actual gap between worldines (the actual 00 or 1.00, is steins gate.
