One Piece: Planet Size Discussion

Status
Not open for further replies.
Just had a thought.

Why don't we assume the planet is "at least as dense as water" considering the planet isn't entirely water (i.e. it is actually denser as it is a rocky planet) this would technically lowball its mass below its true theoretical value; however, it would provide an absolute minimum constraint on density and thus mass.
Or we don't assume anything OTHER than its size.
It's atmosphere seems to match ours despite how big it is, as Sky islands do get harder to breathe on when you hit 10K meters, and water pressure is the same levels as our earth, etc..
It just seems the size is different.

That .... you just took this out of my mouth brother , it being larger is blatant but the least assumptions we make the better

The density for the planet is going to be an assumption either way. I'm more concerned about finding the safest and best assumption. I take no issue either way, whether we go at least water density or flat out earth density.

water is safer, the ratio of water to planet in the OP world is drastically different than it is to earth
 
Assuming the water covers more area IS safe, as the only landmass that makes any difference in the world is the Red Line, but its depth is clearly the same as our world's (10K), unless otherwise is shown.
 
nah it ain't even an assumption
literally every globe shot of the world shows water being the majority
But that only works for its surface, right? It doesn't apply to the density BELOW the water itself since it's still 10KM the same as ours.

yeah, but with that in mind, still the density is less, so unless someone has paper x ray vision and can see how much of the planet is earth and how much isn't, then idk man
 

New calc for it.

I personally think that this is the best calculation that the wiki has for the Planet's size.
It's not assuming the locations of anything (Alabasta on the grand line), not basing it off of the shmega long bridge Tequila Wolf, not pixelscaling anything in fact, just using a distance.

You also get this shot if it makes a difference for the overall more accurate planet based visuals, rather than the map. I can't find a source to it, but the post I found it on a while ago did say it was "official".

2.78x the diameter of the sun.

Neat.

I wonder how this will affect Fujitora's meteors?

Because that'll affect the durability of Doflamingo's strings.
 
Whether the size was twice as big, ten times, or this size- I'm just glad the consistency is there so it doesn't get questioned. The Zunesha timeframe was honestly something I didn't think of. Great job KT!
 
Here's what I have so far.

Geography​

The One Piece planet minimally resembles earth in anyway outside of them having the same shape as a planet.

The One Piece planet's global geography includes
  1. The Red Line: A large number of connected islands which form a super continent, which stretches along the prime meridian of the planet.
  2. The Calm Belt: Two large oceans which border the North and South of the Grand Line. It is always calm, never having any ocean currents or blowing winds.
  3. A large Ocean dubbed "The Blue Sea", which is split up into 5 parts.
    1. The North Blue: The Northernmost ocean in the Blue Sea.
    2. The South Blue: The Southernmost ocean in the Blue Sea.
    3. The East Blue: The Easternmost ocean in the Blue Sea.
    4. The West Blue: The Westernmost ocean in the Blue Sea.
    5. The Grand Line: The Middlemost ocean in the Blue Sea which stretches along the equator of the planet.
  4. The Planet is revealed to have North and South Poles by Buggy and Shanks, and brought up again from where Surume is from.
  5. The Sea Floor: A constant landmass formed of the world's crust which reaches to over 10 Kilometers deep, whereas the average Sea Floor in real life is less than 4 Kilometers deep, and the deepest part of the sea in real life is the Challenger Deep, which is 10.9 Kilometers deep.
    1. The Sea Floor can be argued to be over 15 Kilometers deep, shown during chapter 647-648 where the 5,000 meter long Sea Kings appear to be much shorter than the distance under Fishman Island, which is 10 Kilometers deep.
  6. Reverse Mountain: An extremely large mountain 10 Km above Sea level, while our tallest mountain (Mount Everest) is 8,848 meters above Sea Level
  7. The Planet has a plethora of islands
    1. Stated to be at least 20 million islands
    2. Islands in the Sky
    3. Islands under water
    4. Several different Archipelagos like Sabaody, Totto Land, Long Ring Long Island, and many more
    5. Completely different islands than the ones we have in real life
The main point is that the Planet's Geography is different. Aside from the North and South Pole, the continents are different, the landmasses are different, and more. In fact, they never refer to it as Earth.

Climate​

The One Piece planet's climates drastically differs from earth's.

The Grand Line​

The Grand Line alone has dramatically different climates and mechanics than our world does.

One point is that the islands on the One Piece planet, specifically on the Grand Line, have their own magnetic fields. Their dramatically differing magnetic fields cause insane weather issues like the ones in Chapter 106, which were specifically stated to be caused by seven close magnetic fields from Reverse Island by Vivi in Chapter 115.

The ocean currents and weather patterns are extremely volatile and inconsistent to where they can drastically change instantaneously. Random water spouts, storms, blizzards, heat waves, thick fog (all of that, Chapter 106), and incredibly large cyclones (Chapter 130) are the norm on the Grand Line.

The ridiculous weather patterns are based on the differing climates and magnetic fields clashing. The Grand Line is stated to have islands with 4 different classifications (Summer Island, Spring Island, Autumn Island, and Winter Island), and each type of island has 4 seasons of their own (Chapter 132), in total, 16 different climates not including unknown climates and exceptions.

On the grand line, underwater there are underwater caves filled with gas, and when they explode, they can send powerful sea currents upwards in the form of "Knock up Streams", shown in Chapter 236 and Chapter 996. These happen five times a month.

The Atmosphere​

The Atmosphere of the One Piece planet is drastically different from earth.

For starters, the Atmosphere is hinted to be much larger, hinted with the fact that people can travel to the moon via methods requiring air.

It is said in the real world that it is impossible for balloons to reach space since they expand to the point of combustion at 10 Km. This is shown to differ from the One Piece planet, since in Enel's Cover Story of Chapter 453, the Automata reach the moon via using Air Balloons.

The atmosphere having that quality is not contradicted. In fact, it's supported. Enel uses the Ark, Maxim, which uses multiple rotors and propellers to help it fly, to get to the moon. His backup is 200 Jet Dials, which uses air to accelerate whatever it's connected to, in case anything happens to keep the ship in the air for an hour (Chapter 285). We can see the propellors working in space in Chapter 428, and we see that Enel arrived in Chapter 429.

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.

The Atmosphere 7,000 and 10,000 above Sea level can also handle and create dense clouds that can maintain holding ships and people, referred to as Sea Clouds and Island Clouds.

The Size​

The planet is flat out bigger.

Alabasta​

We have the Alabasta river scaling which makes it to where the 50 km river is like a dot on the map of alabasta, which is tiny compared to the grand line, which is smaller than the red line, which is drastically smaller than earth.
We have a map of the Loguetown Novel which is based off of Oda's concept art of the world. Nothing there is shaped like Alabasta, and that's around where Alabasta would be.
We have many maps and we see that Alabasta is never known to be that much bigger.

Wano​

We also know Wano, a large country in itself, which dwarves Onigashima, another large island in itself, is known to be tiny to the red line and to the world.

Kuma's Movement​

We know Kuma sent the Strawhats flying for 2-3 days and they only got to places relatively close to their original location in the world (the calm belt).
For them to have traveled the diameter of the earth in 3 days (the lowball), they'd need to be moving at 73.7384259259 m/s.

Newsflash, they moved much faster. People scaling above stated Lightning speed characters couldn't track their movement, and they moved that for 2-3 days.
And they deadass just stayed relative to their location in the world compared to the globe. The planet is much larger.
So the planet is relatively very huge.
Agree with everything from here.
 
Understood.

Congrats on getting the planet size accepted, btw.

I can tell this has been a subject that's bothered you for quite a while.
bothered me since i joined the wiki, and thanks

preciate it, thought of this method a long time ago while (imma be transparent) saying Zunesha travelled that distance for a thousand years, got some galaxy sized stuff
 
He needed to be at the right place at the right time i guess , like if zun was not there during luffy's awakening this whole thing would have been mostly useless
 

New calc for it.

I personally think that this is the best calculation that the wiki has for the Planet's size.
It's not assuming the locations of anything (Alabasta on the grand line), not basing it off of the shmega long bridge Tequila Wolf, not pixelscaling anything in fact, just using a distance.
I've evaluated it.
 
Not sure how this works, but Roger traveled round the entire world in less than a Year, I mean he visited all the location where the Poneglyphs are, all within a year. And I think it was directly stated that he made a full round trip around the world iirc
Would try and find the chapter when I’m less busy.

That's true, but there's too many factors in that for that to be a proper distance calc statement.

Luffy also has traveled mostly around the grandline in less then a year. in fact he went from the east blue, then went to the grandline never going in a straight line during it, has had many detours to islands (Water 7-Enies Lobby-Water 7) and has spent a large portion of his time on islands.

Why not just scale directly from Alabasta? If you noticed above? There are no islands large enough near Alabasta to be visible from our bird's eye view. To account for this, we need to scale from the distance between islands on the Grand Line as shown on the globe. Where I scaled is likely not even Alabasta, but the odds are pretty good that Alabasta's not even an island large enough to be seen on the scale of the globe anyway.

A few minor nitpicks with the above Alabasta calc
When measuring the distance between islands you go off the panel by a slight bit
Alabastas river also looks more then 3 pixels wide.

Not the most comfortable using distance between islands, as it varies, but it’s not bad at all

This is an interesting video on the one piece planet, might give some info and supports

Tho my brain gets destroyed with the amount of numbers/calcs and stuff
