One Piece: Planet Size Discussion

[GodlyCharmander]

The fact we have a rocky planet so vastly larger than earth indicates higher gravity…

It doesn't. it hasn't been portrayed as such. You're appealing to reality.
As said by other staff before, a planet, in a fictional setting, can be the size of a solar system and still be normal.

God, even in popular media like DB we have a galaxy sized planet where a normal human can stand. (Obviously it's just an example of the author giving zero ***** about physics).

Literally, @KingTempest made his point clear, One Piece is almost completely unrealistic when it comes to physics, so assuming the planet has... I dunno 10x, 30x (whatever the result is) higher gravity without any narrative indication, or World Building pointing towards it through a fan-calc is wild.

I was under the impression Oda was vastly recognized for his impressive world building, about how his world works, and even his wonky physics with swimmable clouds, yet, he never even hinted at the gravity of his world being far higher than the one on our world? That's wild.

I reiterate, I agree that the planet is far, far bigger than ours, but I disagree with the scientific consequences being accurate to said size unless Oda clearly depicts them.

 

[GodlyCharmander]

Do we have any canonical weight in OP?

 

[DemonGodMitchAubin]

Sorry, I misinterpreted your feat for Deus Sema.

But since you still analyzed stuff like the planet's GPE and other qualities of a planet larger than Earth, maybe you can provide some aid to this chaotic thread?

I used the same gravity as Earth for FT's Planet, but FT's Planet was lowballed to be only like 3x Earth, it's not like like this Sun sized planet shit

 

[KingTempest]

for some animals yeah, not for people

 

[SnookB]

Likely not sun sized. The most recent calc (And the one I agree with most) has it bigger than Jupiter.

 

[Eseseso]

Ok then.

Sorry for dragging you into this.

 

[Arc7Kuroi]

It doesn't.

No it certainly does. Logic dictates if the planet is different than Earth, clearly OP planet is, then it’s parameters would be different as well. Since we no longer treat OP as Earth, there’s nothing to assume it has Earth gravity.

 

[Eseseso]

I'm with this.
This is about the planet, not the solar system. For all we know the rest of the planets are just as big and the sun of the verse is just ridiculously huge as well.

Stop trying to apply real world logic to a fictional verse. The arguments just don't work.

 

[GodlyCharmander]

Wouldn't this possibly be an ""anti-feat"" for the higher gravity in particular? If the animals have a reasonable weight for 1g, then Oda didn't care about gravity of his larger planet.

 

[KingTempest]

ohh u said weight

mass only. weight, no

 

[GodlyCharmander]

ohh u said weight

mass only. weight, no

U funny af, huh?

 

[KingTempest]

U funny af, huh?

Very, we knew this

 

[Eseseso]

I always did hate physics classes in high school.

Not inherently.

Also tempest mass and weight are technically different but in the way Charmander is referencing they’re the same lol

 

[GodlyCharmander]

Tempest.

Kilo Kilo no Mi,
Ton Ton no Mi.

Stop, weight is being portrayed normally in the OP world bro

 

[GodlyCharmander]

Nah, I said weight. Mass is just density×volume, weight is taking gravity into consideration.

Either way, yes, a normal weight would likely mean gravity is being ignored, and Oda is using our world as a frame of reference on that, specifically. Unless we assume the things have a lower density to compensate, which is wild af.

 

[SnookB]

What is this argument even about? The world having a higher/lower GBE than it should? Can't we save that UNTIL we've resolved the size issue?

 

[GodlyCharmander]

Gravity.

 

[KingTempest]

Tempest.

Kilo Kilo no Mi,
Ton Ton no Mi.

These raise mass bro.

As they do raise weight, using regular mass units isn't an antifeat for weight.
Stuff like 1 kg shouldn't exist now?

 

[Arc7Kuroi]

Nah, I said weight. Mass is just density×volume, weight is taking gravity into consideration.

Either way, yes, a normal weight would likely mean gravity is being ignored, and Oda is using our world as a frame of reference on that, specifically. Unless we assume the things have a lower density to compensate, which is wild af.

Well what a scale measures for your weight is your mass at earth’s surface gravity, aka m at g = 9.81, so Oda’s given weights would just mean they’re likely measured at g = OP g, aka they aren’t equivalent to earth weights. Albeit I will agree Oda likely isn’t even considering that.

 

[Damage3245]

The fact we have a rocky planet so vastly larger than earth indicates higher gravity…

Anything else?

 

[Nierre]

I always did hate physics classes in high school.

I second this.

 

[Planck69]

Wait, I'm a bit confused. Is the issue that the planet being larger is invalid due to lack of scientific support or that the planet being really large automatically means that gravity should be proportionately higher?

 

[Arc7Kuroi]

Anything else?

Forgive me for presuming but like are you seriously wanting me to try and break down the logistics of this planet from my astrophysics background or is this sarcasm

 

[Damage3245]

I'm just wondering what evidence do we have for the planet's level of gravity being significantly higher than Earth, and wondering if we had anything other than deducing it based on size calcs for the planet.

While the conclusion you get may be as a result of logical deduction from the material the world is made of and the calced size of it, the lack of support for that conclusion from the actual manga itself makes me hesitant.

 

[SnookB]

Wait, I'm a bit confused. Is the issue that the planet being larger is invalid due to lack of scientific support or that the planet being really large automatically means that gravity should be proportionately higher?

The fact that it's bigger was already accepted. But the argument now is whether or not its gravity is higher than earth or not, based on its size.

 

[SnookB]

Oda can be scientific at times but I also highly doubt he's considering the world's scientific accuracy to a hundred. The most accurate he's been with earth's rules was the ocean depth.
We're using our own real science as a RULE for the One Piece world when as mentioned earlier- other verses have massive worlds that can reach galactic sizes and still have a regular atmosphere, regular density, and humans don't get compressed to less than half their size when existing in them.

The One Piece world has its own laws and rules, and while it's bonkers in some areas and normal in others- I think it's the SAFEST play to just say its gravity is the same until otherwise is shown.

 

[GodlyCharmander]

Well what a scale measures for your weight is your mass at earth’s surface gravity, aka m at g = 9.81, so Oda’s given weights would just mean they’re likely measured at g = OP g, aka they aren’t equivalent to earth weights. Albeit I will agree Oda likely isn’t even considering that.

It would likely have to be 9.81g, instead of the scientifically accurate number. Or different density for people and stuff, which is a very extraordinary claim.
We'd have, if real life is to be considered, people weighting tons, and the whole point of the Kilo Kilo and Ton Ton fruit would be kind of lost.

These raise mass bro.

I will pretend you didn't say that.

 

[Arc7Kuroi]

If you give me until the weekend I can better give a response, but the tldr is we know the planet is denser than water because it’s a rocky planet + water, so that plus massive size indicates it’d have higher gravity, hell the sun and Jupiter are far less dense on average earth and gaseous yet have higher gravity than earth.

 

[KingTempest]

Wait, I'm a bit confused. Is the issue that the planet being larger is invalid due to lack of scientific support or that the planet being really large automatically means that gravity should be proportionately higher?

They want to accept the planet being larger but not the gravity of the planet

 

[SnookB]

Reminder that the gravity being higher effecting ANYONE being an issue shouldn't even be a thing, considering "fodder" in One Piece can tank knock up streams

 

[Planck69]

They want to accept the planet being larger but not the gravity of the planet

Is there any actual canon indicator for higher gravity or reference to the correlation between its size and gravity? From what I understand and have seen, we usually just treat these sorts of planets as having Earth gravity unless shown or implied otherwise. Could be wrong.

 

[KingTempest]

Doesn't the atmosphere's issues also correlate with gravity?

 

[Arc7Kuroi]

The issue with that is, assuming earth gravity makes the OP planet 10x less dense than water, and denser than gas giants like Jupiter. And we can all agree OP is a solid planet, not a gaseous one.

 

[Majinere566]

Saw a Point about the planet now becoming the center of the solar system since its bigger than our sun

Logically assuming, since the planet is this big wouldn't that make the sun in the one piece world even bigger since the one piece earth orbits around it?

 

[Damage3245]

The issue with that is, assuming earth gravity makes the OP planet 10x less dense than water, and denser than gas giants like Jupiter. And we can all agree OP is a solid planet, not a gaseous one.

Nobody is arguing for the planet to be gaseous.

 

[KingTempest]

We don't even know how the solar system of OP works

Can we not talk about something of that nature?

 

[KingTempest]

Nobody is arguing for the planet to be gaseous.

Arguing that it has earth level gravity with a large size automatically makes the planet have a gaseous density

 

[Arc7Kuroi]

I guess if we wanted to strictly lowball it’s density and thus mass and gravity, the lightest rock according to google is pumice which has a density of 700-1200 kg/m^3 (water is ~1000 kg/m^3 for comparison).

 

[Planck69]

The issue with that is, assuming earth gravity makes the OP planet 10x less dense than water, and denser than gas giants like Jupiter. And we can all agree OP is a solid planet, not a gaseous one.

I mean, that runs into the issue of at what point physics should be focused on instead of the narrative. Like, if One Piece's world was sun sized or larger then you could easily just point out how it'd collapse in on itself.
