He’s just one big buoyant boy.
My head canon for sea-based Kaiju is they have a sack of muscles somewhere inside their body that can expand a cavity, kind of like the diaphragm expands the lungs, except instead of taking in air or water it just creates a volume of vacuum inside of them. This makes them extremely bouyant relative to the surrounding sea pressure, so they rapidly ascend and can casually float like a boat near the surface.
But if they ever want to dive again, they just let that cavity collapse and all their bouyancy goes away.
I dunno. Seems a little unrealistic!
To get unnecessarily scientific here, that wouldn’t change the overall density of the body, no? Even if there’s now a cavity with vacuum, the matter that was occupying that space just moved somewhere else within the volumes of the body and the overall density remained the same.
Now, if it pushed some matter out, air or water, and created a vacuum cavity, that might work. But I’m not an engineer, so correct me if I’m wrong.A hundred ton steel ship floats, a hundred ton steel block does not. Density equals weight per volume. If you increase the volume without increasing the weight, the density will go down.
Exactly my point, the volume doesn’t change in the example provided. Weight and volume stayed the same. We either need to expand Godzilla or it needs to eject some mass.
In the example he gave, he mentioned lungs expanding, so volume IS changing. Godzilla can shoot lasers in current lore. He could easily have some super compressed ballast tanks as organs that release pressure changing a whole slew of variables.
If Submarines have ballast tanks of 600 pounds of air at 3000 PSI, Godzilla can have his own magic organs that do crazy stuff.
Expansion of lungs makes us float because our whole body expands significantly, relative to our small volume.
In the examples mentioned above, the organs creating vacuum are said to be “somewhere inside” the body. Vacuum or not, Godzilla needs to visibly swell to increase its volume and buoyancy, which we don’t observe.The air in submarines is used for pushing the water out of tanks, so the principle is ejecting matter. If Godzilla were to use that approach, as I said before, it needs to eject something.
I think that it’s implicit that the volume of Godzilla would increase; we need to assume that the bounding layer has a degree of elasticity and that that the matter displaced by the flotation cavity will expand into that, reducing the net density.
Mighty Godzilla, with power untold
Rises through the waves; his powers unfold
Hidden muscles in clever design
Create a new chamber as they realign
Inflating his body, a titanic display
Defying the depths, he floats up and away
No long bound by the oceans’s might
Godzilla soars, a triumphant sight!
Yes, that would work. But imagine the swelling, to give Godzilla that much buoyancy.
Ordinary biomatter is very close to the density of water to begin with. That’s why having a little air in your lungs is enough to be the difference between sinking and floating.
If Godzilla’s biomatter under 1atm of pressure has a density close to water then being able to compress or expand an empty chamber inside his body by even just a tiny percentage of his ordinary overall volume could be the difference between floating at sea level or sinking to extreme depths.
Or if you prefer we can imagine that Godzilla gives himself a big ole booty when he needs to come up to the surface and make a mess of things.
I hope you get cited when they put this dialog in the next movie
I just don’t know why I’m getting booed, I’m right.
You’d be right if the cavity is only compressing other organs inside the body without changing the overall volume, but I don’t know why you seem to insist on making that assumption.
I thought it would be clear from my original description, via the analogy with lungs, that the cavity would not squish the internal organs but rather expand the overall volume of the body.
This is further proof that for every statement made, no matter how whimsical, there exists at least one person online who will tell you that you’re wrong.
-The Earth revolves around the sun.
-Ackchyually, they all revolve around the galactic center…-Godzilla floats by increasing his volume.
-Ackchyualllllly, his volume doesn’t increase because lungs are on the outside… (Wtf?!)-Cotton candy is my favorite fair food.
-Ackkkkkkchyualllllllllly, my review of the last three years of your comment history proves your favorite fair food is not, in fact, cotton candy. I have gathered and will prove this with ten points. Point one: your childhood experience with Geoffrey the Giraffe suggests…
Whimsical or not, there was a scientific misconception used in the statement, that I myself used to have as well. My only goal was to help dispel the misconception. Usually, Lemmy is quite welcoming to correction of scientific inconsistencies in sci-fi discussions. Idk what happened in this particular thread, but it went off the rails. All my statement got misconstrued and downvoted, despite me engaging in the discussion in good faith and being factually correct. Several people showed up, making incorrect or irrelevant statements and got upvoted.
Like your “lungs are on the outside” comment. Maybe you can explain to me, why am I being antagonized and intentionally misunderstood? Obviously I didn’t mean that lungs are on the outside, context matters. And I explained the context in another comment.
I made that assumption because lungs aren’t really inside, they are pretty close to the surface, so they are easy to expand. If they were inside, they would have to push other organs away.
And regarding increasing the overall volume of the body, I addressed that in another comment. Basically, Godzilla would have to visibly swell by a lot, to have that much buoyancy.
It could be that the swelling is only in the underwater part, but then Godzilla would tip over with any slight movement, because the center of mass would be way above water.“Lungs aren’t really inside” is not an argument that I thought I’d be confronted with.
If you find that your lungs are not inside your body then I urge you to seek immediate medical attention.
At this point, you’re just trying to ridicule me over my choice of words and not actually trying to interpret them in the context that you yourself set:
they have a sack of muscles somewhere inside their body
Why mention “inside their body” if you didn’t mean “deep” inside? All organs are “inside” the body. Therefore, I interpreted your words meaning truly “internal” organs, that that don’t manifest themselves on visual inspection, like heart or bladder. Lungs, while technically inside, are peripheral and visibly expand - a critical distinction in this context.
So you specify “inside” and then mock my adherence to that framing, instead of addressing the core biomechanical issues being discussed.
Ducks and other waterfowl have the majority of their weight above the waterline. So do boats.
Yes, but birds are very light in general. Most of their volume is feathers and they have a low bone density to boot. As the result, they have a very hard time diving, and have to either dive at high speed or paddle really hard to stay underwater.
And regarding boats, it depends. Do you mean completely empty passenger boats? Then yes, their density is very low by design, because they are mostly empty on the inside. When fully loaded, a commercial cargo vessel, is 80-90% under water.
You can’t prove that Godzilla’s bones aren’t hollow ballast tanks that can be emptied and filled as needed.
When fully loaded, a commercial cargo vessel, is 80-90% under water.
Hahaha, no.
While I can’t find a comparable article for cargo ships, cruise ships are 10% underwater. A fully loaded cargo ship can’t be more than 30% as they tend to be stacked far higher than the ship’s sides. Ocean waves would easily swamp a ship that was 80-90% underwater.
💯 This is the true answer
It’s spelled ‘buoy’
It’s way cuter if he’s kicking his stubby ol legs
Godzilla is a duck confirmed
Quackzilla
I like to think he’s treading water, Godzilla is an expert in synchronized swimming.
Yeah all the above is head canon for me now.
Squid locomotion.
Case closed
Good work Ducktective, what would we do without you…
He came from the deep ocean, and nobody thinks he’s just the absolute master at treading water?? SMDH
I mean he clearly just walks out of the water in the movies, he’s not suddenly coming up, like you clearly see him slowly get higher and higher out of the water as he gets closer to shore. Also the ocean isn’t that deep close to shore.
OMG is this what whales do too? What about other fishes?? What have they been lying to us??
And boats and icebergs. Even me. I can’t swim, I just extend my legs. and fake it.
He’s firing from both ends.
or maybe its godzillas stacked all the way down.
Godzilla is Kaiju Jesus
I mean, most people doesn’t even question how a dude walked on water, either.
He was the son of Godzilla, after all.
The new Godzilla Minus 1 movie actually goes over this, >!they even use it against Godzilla to try and defeat him.!<
He’s obviously built himself thousands of little elevators over millenia. What did you guys think he was doing down there? Sleeping?
In his house at R’lyeh
Yes.
Finally a pertinent question. Thanks
Everyone is in here talking about Godzilla legs.
No one is talking about the Godzilla pizza slice.
