One Piece General Discussion: Elbaph

The formula for finding the radius of the planet is...

R = (d^2 - h^2)/2h

d = distance to horizon

h = height of eyeline of viewer

R = radius of planet
Interested in sum, you can also use the Merry in chap 160 for height of eyeline viewer (gotta calc how high the standing part of the Merry is) but yeah

NEVERMIND YOU ALREADY DID
 
With the way its being used, I don't believe it matters. It is normally using planet radius and viewing height to find distance to horizon but we already have the distance to the horizon which can be reverse engineered to find planet radius. Atmospheric refraction seems to only affect the distance to horizon, if you're using planet radius and viewing height.
It would still matter since atmospheric refraction can let you see a horizon that is further away than normal.

Granted, I don't know much of an effect it would have, so it might not mean too much.

A. It's a small number change in the grand scheme of things.

B. Using 50 km is already a lowball as most POV shots aren't at the bank itself and usually show way more than just the width of the river.
 
I've come with another end. The advantage of this version is that it doesn't require calc stacking, doesn't require pixel scaling, uses official/canon sizes, and uses official manga art. It merely applies a canon size/distance and pumps out a scientifically verifiable number.
Great work! 🙏🙂❤️

I tried asking ChatGTP how much it would change, this its what i got:

Still around Sun's size either way.
 
Hey so awkward question but is there any knowledgeable on OP staff members I can ping/e-beg to look at the Devil Fruits Page CRT since I was told it needs just one more staff vote? IK we're focused more on the scaling atm but I do want this done at least
 
Something that came to mind today:

Some other point.

If the picture of the triangle is accurate, one could deduce the distance between each of the three positions based on the fact that the time it takes to reach one of those places is known - the Tarai Current, which is supposed to be some super fast maritime express highway, supposedly allows for 3 days worth of regular (who knows if wiki makes sense)? travel in 30 minutes, and that the travel time supposedly is 1 week from Amazon Lily to Impel Down or 4 days if one goes to the Tarai Current first and then heads there? - moves things between places AND we got at least some understanding of what maximum speed the Going Marry can take and what standard speed is assumed could be deduced from other things, too.

As it has been a long time since I've had some clearer look at that part of the story, maybe someone else has some deeper insight into this issue?

Nice job, although there are some problems I noticed with this calc.

1)The third version doesn't work. When we talk about the height above average surface level regarding the horizon we are talking about sea level (The distance to horizon calculator points this out since all the formulas are adjusted to sea level) and considering that the distance between the pov of Vivi and the other side of the river is covered in water what we care about is the height above sea level.

2)The deck to sea level height can't be .23m as in chapter 99 Oda provided us with a diagram for the going merry and below the deck there are the men's and women's quarters. We can just calculate the height of the women's quarters which would be 3.52m (We know that's the room because of another of the diagram's provided) and then use that and assume that's the full height of the deck above sea level. We should add this value to Vivi's eyesight height in the other 2 versions since our surface of reference is sea level. That relatively small height on its own changes the result for the planet's radius drastically from 806,643 km to 246,717km, so yeah it can't be ignored.

3)Another major problem is that the objects we're looking at from the other side of the river are mountains which are elevated above sea level. These tall objects can be viewed from beyond our horizon distance. In this calculator we can put the height of the observation point and the height of the object beyond the horizon to find the maximal distance at which the top of this object will be visible using earth parameters. We can use this calculator to approximate the minimal height needed for an object to be visible from a certain distance, for example the minimal height needed for an object to be visible from 50km away at the height we have is 115.3m (137.9m for the height of Vivi's eyes), obviously a taller mountain even more visible from 50km away (what we'll be able to view is the difference between the mountain's height and the minimal height required that we calculated earlier from the top, if the mountain is a good amount larger than the minimal height then you'd see most of it and won't notice the missing part at the base). Considering Alabasta is a pretty mountainous kingdom it's not that ridiculous to assume that these mountains that we see in the other side of the Sandora River are much taller than these minimal values, so the fact that they are visible from 50km away doesn't really give us the info needed to find the diameter of the planet.

And to illustrate this even further since the previous calculator uses earth parameters this time let's use the parameters of a planet arbitrarily larger than earth and smaller than the one found in the blog for example one with a diameter of 40000km, to find the apparent radius of the planet due to atmospheric refraction we will use this formula/This formula, while the formula for the maximal distance between two points we can use This which is d = sqrt(2*R*h1) + sqrt(2*R*h2) we can then use this to find the formula for the minimum height of an object to be visible from a certain distance to find h2 = (d - sqrt(2*R*h1))^2 / (2*R). For our 40000km diameter planet we'll use in this example the radius will be 20000km and the apparent radius due to atmospheric refraction will be 20000*7/6=23333.33km=23333330m for 50 km away we'll have h2 = (50000 - sqrt(2*23333330*(5.071)))^2 / (2*23333330) = 25.68m ((50000 - sqrt(2*23333330*(1.551)))^2 / (2*23333330)=37.9m if we were to use Vivi's eye height rather than the full height which still gives us a short minimal height), so in this planet with 40000km diameter you can see objects as short as 37.9m from 50km away and as such the mountains will be easily visible from that distance since 37.9m is a negligible value compared to their heights, so we really can't deduce the planet's diameter with the method used in the blog which gets a 1,611,864 km diameter planet (a very large difference from the 40000km used here) for viewing these mountains from 50km away. (For a planet with a diameter of 90000km (50000 - sqrt(2*52500000*(1.551)))^2 / (2*52500000)=13.2m which is pretty much nothing when we're talking about mountains)

4)This is more so just a nitpick but I think another problem with using the distance to horizon to calculate the planet's diameter is that Oda is inconsistent in drawing the distance to horizon. For example, the coup de burst which we canonically know launches the Sunny 1km away made the ship go to the edge of the horizon being barely visible. So I think opting for other methods would be better.
 
for point 4, if it's canonically stated that something isn't beyond the horizon, then it does not matter regarding the art
 
2)The deck to sea level height can't be .23m as in chapter 99 Oda provided us with a diagram for the going merry and below the deck there are the men's and women's quarters. We can just calculate the height of the women's quarters which would be 3.52m (We know that's the room because of another of the diagram's provided) and then use that and assume that's the full height of the deck above sea level. We should add this value to Vivi's eyesight height in the other 2 versions since our surface of reference is sea level. That relatively small height on its own changes the result for the planet's radius drastically from 806,643 km to 246,717km, so yeah it can't be ignored.
Why not the official height of the going Mary, that would be a lot safer since it doesn't use an external calc.
 
I wonder how well received the live action is in japan
Answer from ChatGPT. 🙏

"In Japan, the Netflix live-action One Piece seems to have been received well overall—better than many fans initially expected—but not as a singular national phenomenon on the level of the manga/anime itself.

The strongest evidence points to positive reception among viewers and Japanese entertainment press. Shortly after release, Cinema Today reported that the show had a 94% audience score and highlighted a wave of praise from viewers saying it exceeded expectations, felt faithful to the source, and was binge-worthy. Japanese reviews were also notably favorable: Cinema Today’s review praised the adaptation’s battle scenes, character recreation, and the way it worked as a live-action drama rather than just copying the manga panel-for-panel.

A big part of the positive Japanese reaction seems to be that pre-release skepticism softened once people saw the footage. Japanese outlet NLab reported that teaser reactions were largely positive, with comments calling it “解釈一致” and praising the casting and visible “original-love” in the production. Another NLab piece noted that the Japanese dub using the anime’s established voice cast was especially well received, with fans praising how well the performances fit the live-action version.

On the popularity side, it clearly had real traction in Japan on Netflix, even if that is not the same thing as dominating all of Japanese pop culture. Japanese reporting in September 2023 noted that the series held Netflix’s TV top spot for two consecutive weeks globally, and current Netflix Tudum rankings still show One Piece highly placed in Japan, which suggests durable local interest rather than a one-week novelty.

So the best summary is:

Japan’s verdict was broadly positive:

fans and reviewers generally thought it was surprisingly faithful and competently made;

the Japanese dub and visible respect for the source material helped a lot;

but it was still more of a successful Netflix adaptation for fans and streaming audiences than a society-wide cultural event equal to core One Piece manga/anime fever. That last point is an inference from the evidence: the sources strongly show approval and streaming popularity, but not the kind of mass, cross-platform frenzy you’d associate with the franchise at its absolute peak."
 
 

Matchup dates are announced
 
this is the main reason why I'm beginning to dislike Sanji more and more ngl 🙈 but I'll stay strong against his annoying fanbase 😤 (not saying you annoying tho, most sanji fans are unfairly biased and take things too far) it's like being a Luffy fan and spam saying he's smarter than vegapunk... Idk something like that
they'll nitpick the smallest thing and want it to become something that's entirely focused on Sanji while legit not caring about anything else and the overall product... I'm talking about those people
This what I'm talking about... 😴

HEBkq21bcAA8_T5
 
The dates that this encompasses is 3.9 to 3.15. The large influx of votes happened from 3.20. Please get your facts in order.
you honestly believe Sanji is number 1 randomly when he wasn't before...? No matter the date... You can clearly see its botted especially for Sanji the most

HEF2dvHboAAL6Zf

That's absolute denial...
 
Sanji became number 1 in two regions that he was number 2 in. If you consider that outlandish then that's all you.
It is outlandish... What I'm seeing from sanji fans themselves on social medias trying and wanting to bot is all I need to see.
 

We need you OP supporters. Your goat is in need of help, it’s your guys’ time to shine.
