One Piece Blue Planet Calc Revisions

[HammerStrikes219]

Dude.
If he is saying
"Light refracts downward, causing lower objects to appear higher, which makes the horizon distance seem closer out, so it needs to be lowered to be more accurate"
And I'm saying
"The opposite effect is the case"

Then it means that I'm saying
"Light refracts upwards, causing higher objects to appear lower, which makes the horizon distance seem farther out, so it needs to be increased to be more accurate"

The entire point is that the opposite of what he's saying is the case.
The coast is being made to look like it is farther out than it really is, aka the coast is being made to appear like it's further away, and in fact it's not the case, it is closer, making the true horizon distance larger, making the planet larger.

Venus has an thick C02 atmosphere 90x the pressure of earth based on the runaway greenhouse gas effect from volcanic gassing and a lack of tectonic plates which hold carbon into the crust of the planet.
For this to be valid, it would need to have the same mechanics as earth, not something 90x the pressure based on a completely screwed planet.

The Coast isn’t heated though and Vivi was talking about the desert and shouldn’t been under a mirage compared to a desert and its mirages.

The mechanism of formation of desert mirages

The mirage is a unique optical phenomenon in the desert. This paper investigates the mechanism by which they form. Optical experiments in the Gobi show that the refractive index decreases about 20 to 40 cm above the ground causing a total reflection of ground surface light. Thus, ground light...

However, what you quoted only works in a specific timeframe which is afternoon.


Afternoon, by definition, noon to 5:00 to 6:00 PM by Earth standards here.

Mirage of astronomical objects - Wikipedia

Speaking of mirages, I don’t think we can feasibly claim these panels as being under a mirage.

The one posted by Ymr as claiming there is a mirage during the later parts for the Alabasta Arc is not possible.

 

[Qurbonboev]

So no. In fact, this would increase the true horizon distance.

Yes, in this particular scenario it would probably force us to increase estimated true horizon distance(thus 1,600,000 km would be lowball). IF atmosphere on Alabasta had same density, temperature and pressure profile and gradient as Earth, which it obviously doesn't. And I don't need to explain to your this.

My argument is that we shouldn't use horizon method at all.
Something as simple as having a higher lapse rate (in this case temperature drop rate by height) on the surface (only for 1 m), could drop apparent horizon size from 16 km to 100 meters. And we know that One Piece have much lower lapse rate than Earth, since it can support airdrops at 114,000 km height, which indicates at least 30 times slower temperature drop rate than Earth atmosphere over entire height of atmosphere.

To recap:
1. To find radius of the planet you need exact data of global and local density, temperature and pressure profiles(they are interconnected, so you could theoretically do this with only one of them).
2. If you somehow managed to find this data, it prolly would give results that are wildly incongruent with realities on the ground. Things like "Sandova River shouldn't exists, water doesn't exists in liquid form under such pressure".

Venus has an thick C02 atmosphere 90x the pressure of earth based on the runaway greenhouse gas effect from volcanic gassing and a lack of tectonic plates which hold carbon into the crust of the planet.
For this to be valid, it would need to have the same mechanics as earth, not something 90x the pressure based on a completely screwed planet.

Only truly relevant part is Venus having thicker atmosphere(greenhouse effects are irrelevant). Any planet with denser atmosphere would have same effect of having bigger apparent horizon.
I didn't read One Piece, but thanks to works of verse sups, I can see for myself that atmosphere in One Piece should be very big and dense(airdrops at 114,000 km and being able to fly to moon via balloons are wild feats).

To being clear, the cloud calcs was left in the air and I am pretty sure there wasn’t any specific values as that was left up to calculation members to decide and determine the density of clouds when it comes to atmosphere conditions and the altitude for the clouds as well

 

[HammerStrikes219]

What the hell do you mean by "I don't need to explain"?? Yes the **** you do. Seriously, what are we doing here

He is saying the One Piece’s planet atmospheric parameters and every known environmental conditions shown in One Piece is evidently different from the atmosphere parameters of Earth itself.

This isn't accounted for in the sense of genuine planet specific mathematics due to things like 7km high into the planet already showing similar issues with breathing and temperature on the planet.

The entire point of the wiki's stances on the planet is
A. It's too similar to earth to consider different planet parameters
B. It's too dissimilar to earth to consider similar planet parameters

Somebody needs to agree because on one side people keep using one to discredit everything and the other uses the contrary

 

[Qurbonboev]

Wait, do we currently accept One Piece atmosphere being geniunely different from Earth and account for this in calcs, or nah? I read that CRT purely to check some facts.

Regardless, even if close our eyes at Blue having different atmosphere, there are still obvious problem. What do you think is more likely?:
1. Horizon at Alabasta is 50 km long due to Blue being Sun sized.
2. Horizon at Alabasta is 50 km long due to some funky atmospheric effects.

Wait, how hot is that river itself? is it cooler or hotter than air above it?:
"In extreme cases, usually in springtime, when warm air overlies cold water, refraction can allow light to follow the Earth's surface for hundreds of kilometres"

 

[Damage3245]

Wait, do we currently accept One Piece atmosphere being geniunely different from Earth and account for this in calcs, or nah? I read that CRT purely to check some facts.

We do to an extent seeing as we assume that the planet's atmosphere is 70,679 km high - though I have numerous issues with that scene such as it not making any sense for rain to be falling from that height as it would take about 130 days to fall that far.

 

[KingTempest]

We have nothing agreed on. People flipflop depending on how they wanna disagree.
There's threads that nuke everything cause "it's a different planet" but when we try to account for the planet in any other occasion, now it's "the planet is earth like"

We do to an extent seeing as we assume that the planet's atmosphere is 70,679 km high - though I have numerous issues with that scene such as it not making any sense for rain to be falling from that height as it would take about 130 days to fall that far.

Exhibit A

1. Horizon at Alabasta is 50 km long due to Blue being Sun sized.
2. Horizon at Alabasta is 50 km long due to some funky atmospheric effects.

Sun Sized.
The fact that we pixelcalced it to a less than 5% margin of error says everything.

It's consistent as all hell for it to be that size and for the horizon to be that long.

Wait, how hot is that river itself? is it cooler or hotter than air above it?:
"In extreme cases, usually in springtime, when warm air overlies cold water, refraction can allow light to follow the Earth's surface for hundreds of kilometres"

They swam in the river so likely colder.

The speed of Rain is 22.37 mph (I rounded up to closest number and converted from the 10 meter per second) on Earth.

How fast do raindrops fall? | NASA Global Precipitation Measurement Mission

This question is tricky because some precipitating raindrops may not fall at all, if the surrounding wind has a sufficiently strong upward component. In still air, the terminal speed of a raindrop is an increasing function of the size of the drop, reaching a maximum of about 10 meters per second...

gpm.nasa.gov

It would taken 7 minutes to reach the ground for the rain drop from a 4,000 meter bare minimum there

 

[KingTempest]

Kaidou cleared a 10km freefall in seconds which woulda took up to almost a minute I'm fine if we wanna say they got higher gravity

 

[HammerStrikes219]

To being clear, this thread is related to this one here:

Proposed Rules for Calcing Planet Sizes (CGM Only)

I have no horse in this race. @DontTalkDT @Executor_N0 @Mr. Bambu Your thoughts on this topic would be appreciated.

vsbattles.com

 

[HammerStrikes219]

Kaidou cleared a 10km freefall in seconds which woulda took up to almost a minute I'm fine if we wanna say they got higher gravity

Again, Damage and M3X_2.0 here agreed that the One Piece Planet is a larger planet compared to Earth.

They ain’t disagreeing with that, what they are disagreeing with is the radius and the diameter of said planet to begin with to say the least.

That is also not getting into addressing the legitimacy of said calculations as it is clearly getting contested here and the other one.

 

[Damage3245]

Kaidou cleared a 10km freefall in seconds which woulda took up to almost a minute I'm fine if we wanna say they got higher gravity

The time of fall you calculated is 45 seconds. The time it took for Kaidou to fall in the anime is 20 seconds. In the manga there is no way to tell how long it took because Oda used those transitional panels at the end of this page and beginning of this page that indicate time has passed; it isn't intended to just be a matter of a few seconds I believe. After Kaidou lands on the ground, the scene does cut back to "a few minutes earlier" so there is enough time for it to have potentially taken Kaidou 45 seconds to fall.

 

[Qurbonboev]

They swam in the river so likely colder.

So we have big river which is relatively cold, and hot air above it.
"In extreme cases, usually in springtime, when warm air overlies cold water, refraction can allow light to follow the Earth's surface for hundreds of kilometres"

To being clear on this, Alabasta is a island surrounding by water in the One Piece planet as I am confused as to why we using a river for a island that is surrounded by a large mass of water that is a ocean and all

 

[KingTempest]

That is also not getting into addressing the legitimacy of said calculations as it is clearly getting contested here and the other one.

And their reasoning has been debunked thoroughly by me and Kachon

Floxy asked for a reason as to why, Kachon gave reasons, BillyBobJoe's reasons were "I still don't think that's the case"

We're here to argue. That's it

 

[Qurbonboev]

Since we can clearly see that horizon method is unusable, let's talk about this clear anti-feat:
"The planet also has enough air to breathe at extremely high elevations, even though it admittedly does get harder to breathe at higher altitudes. According to this website, the max altitude you can breathe in the real world is 20,000 feet, or 6,096 meters. In Chapter 238, we see that the Oxygen is scarce at 7,000 meters high in the sky on the White Sea, but it's still enough to breathe there. This is brought up again in Chapter 242 when they reach the White-White Sea, 10,000 meters high, where there is still enough air to breathe."
Highest IRL settlement is located on 5100 m altitude. So Blue atmosphere is considerably thicker than IRL one, but not to insane degree.
Yet it's possible to reach Moon, which it's calced to be 367243 km far away. Doesn't sounds too consistent.

There its another method propose by YmTheSuper, in One Piece General Discussion, about using Luffy travel between Sabaody and Amazon Lily.

If we use this method and it's value for Blue size, we get distanse of 15638 between Blue and Moon, which is more consistent with thick, but not ridiculously so atmosphere

No. the problem with this logic is that...

Enel, and the space pirates are breathing on the moon with no protective gear or anything of the sort. So... yeah, OP physics are just different.

 

[Floxy178]

Raindrops have very small terminal velocity

To be fair since y'all all agree that OP atmosphere might be different in density, pressure, etc. (even if it isn't true, different gravity will be enough by itself), it surely won't have same terminal velocity.

Anyway, it's a little late for me so I'll probably give a proper evaluation only tomorrow and try to propose to recalc for horizon method. (outside of "if it's lowball or highball" stuff)

Here's how I would personally calculate it.

Spoiler

The speed of travel:
We can use this part of the anime to find Kuma's speed which should be similar to Luffy's since they are using Kuma's devil fruit.

Frame 1, Frame 2, Kuma's size

in 1 frame Kuma moves from the point of coordinates 1222, 717 to 1217, 715 (in pixels)
d = sqrt((1217 - 1222)^2 + (715 - 717)^2) = 5.39px

Kuma height: 6.89m=13px
d=5.39px=2.86m

The video is 24 frames per second as shown here (The title of the video is misleading).

Speed: 2.86/(1/24)= 68.64m/s
The time frame:
Gloriosa stated that it took Luffy 2 days to arrive to Amazon Lily to Sabaody so that's out timeframe

Sizes:
Scan 1, Scan 2
Distance from Amazon Lily to Sabaody: 172800*68.64=11860992m=11860.992km=449px
Half of Grand Line width: 166px=4385.13km

Half of Grand Line width: 30px=4385.13km
Blue planet Diameter: 505px=73816.36km
Corrected planet diameter = sqrt(1-(tan(35)(505/773))^2/((tan(35)(505/773))^2+1))*73816.36 = 67126.43km

Ym did his own method at getting the diameter of One Piece’s planet here to see how things are.

 

[HammerStrikes219]

No. the problem with this logic is that...

Enel, and the space pirates are breathing on the moon with no protective gear or anything of the sort. So... yeah, OP physics are just different.

This is irrelevant to the distance stuff as that is a different can of worms already plus you get non standard breathing type 2 and/or self sustenance type 1

Self-Sustenance

Self-Sustenance is the ability to maintain oneself indefinitely without the typical metabolic requirements of life. The exact nature and functionality of this ability may vary greatly, and for certain types of creatures this may simply be a normal aspect of their being - for example, the undead...

The results of that calc are nonsensical as it demands for Alabasta's diameter being the same as the Grand Line's width.

Which again came from a guesstimate via the blog being contested right now.


Also you just argued out of suspension of disbelief when it comes to fan made calculations that is literally putting a guesstimate on the planet’s size.

I honestly don’t think Ymir is doing anything malicious in trying to find a reasonable estimate.

Also the measurement is 67,126.43 KM for One Piece’s planetary diameter which is considerably bigger than the Earth’s diameter of 12,756 kilometers from NASA and other credible sources.

Facts About Earth

Earth is the third planet from the Sun, and the fifth largest planet. It's the only place we know of inhabited by living things.

You guys are arguing for a higher end just because “Bigger numbers means better results” which I don’t mind, but still will disagree with your assertions and assumptions as I still in agreement with the opposition.

I do not care what the final result of the calculation is, and I never claimed that Ym is acting maliciously. The simple fact is that his calculation puts the Grand Line at 8770.26 kilometers wide, while Alabasta remains 7955 kilometers in diameter with there being no contention to that part of KT's calc makes it objectively nonsensical

The fact that some people in this thread can, in one breath, argue that using the sailing speed of ships makes a large planet impossible, and in the next say they see no issue with Alabasta taking up 91% of the Grand Line’s width, tells me everything I need to know.

Like KT said, you guys switch your arguments depending on what’s convenient, because for some reason you need the planet to be so small that it breaks all consistency.

The planet isn’t smaller than Earth though? You guy’s arguments ain’t solid enough to refute the opposition as again, Damage and the others all agree the One Piece Planet being bigger than Earth itself, but what they are disagreeing on is the estimate for said planet’s size.

You can screams suspension of disbelief all you want, but trying to invalidate the opposition’s points that is contesting the results of the fanmade calculation that is doing the planetary parameters is just a no-go as it is now

I need you to double back and read what I said because I never once mentioned Earth's size.

"So small that it breaks all consistency" refers to Alabasta fitting within 1 out of 7 different routes within the Grand Line yet supposedly taking up 91% of the space that the other routes and islands should be occupying.

"So small that it breaks all consistency" refers to Alabasta allegedly being 400 kilometers away from the Calm Belt on either side despite it being nowhere to be found in any nearby shot of the island.

He using the half of the Grand Line Width from King Tempest’s blog though?

He is dividing the Grand Line Width and other mathematical formulas to get the final results so I not sure on the specific reasoning here now I think about it

 

[EtherealCrater]

If it truly was Oda's intention to have the grandline be that small, he would've illustrated the Calm Belt in some and I mean any way at all. Yet, he doesn't.

Half of the Grand Line's width from KT's blog is 80345.5 km. Ym got a value 5% the size of that.

 

[Stefano4444]

Yeah Kachon as a point, the size Ym got does kinda clash against the size we still have for Alabasta, based on Vivi's statement about Sandora River be 50 km in width.

And its not like with Zunesha's 35 km in height which was stated only in a guidebook only to be changed later, that its a statement from the manga which has never been officially retconned as far i'm aware.

The only way to fix this would be to believe that Vivi for some reason was either lying, or that she didn't know shit, yet nothing in the series point on this direction.

This is not half of the grand line that I got.
That value is barely half of Alabasta the island, not half of the grand line

The grand line is 160691 km, 18 times bigger than what he used.

Hmmm, that is fair, but he using to do a guesstimate of the planet’s diameter either way.

If it truly was Oda's intention to have the grandline be that small, he would've illustrated the Calm Belt in some and I mean any way at all. Yet, he doesn't.

The perspective of size can been skewed when it comes to maps, wide screenshot, and so on tbf.

Not to mention even with that mind, we still relying on a lot of maps and other as we do have to assume they are drawn to scale and all ignoring any inconsistencies and stuff

 

[Qurbonboev]

Enel, and the space pirates are breathing on the moon with no protective gear or anything of the sort.

IRL Moon has (practically) no atmosphere because it's escape velocity is too low to prevent escape of gases.
One Piece Moon doesn't have such problems.

Anyway, it's a little late for me so I'll probably give a proper evaluation only tomorrow and try to propose to recalc for horizon method. (outside of "if it's lowball or highball" stuff)

Will wait for it. Thought I still maintain position that apparent horizon is too sensitive to local atmospheric phenomena to be basis for such an important calc.

To be fair since y'all all agree that OP atmosphere might be different in density, pressure, etc. (even if it isn't true, different gravity will be enough by itself), it surely won't have same terminal velocity.

1. I am pretty sure that having thicker air would make drag stronger, thus terminal velocity lower.
2. I don't have a problem with raindrops reaching ground too fast. Moment would be ruined if Oda draws airdrops reaching ground after hours. I have problems with existence of airdrops at 114,000 km altitude.

Snip

Snip.

1. What is known about Moon gravity? Is it noted to be stronger or weaker than Blue?
2. Is exact value of distance between Moon and Blue is used for any calculations?

I mean, Vivi was only born and raised there for 16 years and is the princess of Alabasta...what would she know about her home country? Clearly, she is an unreliable source.
