I dunno. Seems a little unrealistic!
Comment on Another mystery solved.
5C5C5C@programming.dev 1 week agoMy 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 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.

To get unnecessary 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.5ibelius9insterberg@feddit.de 1 week ago
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.

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!

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.

I hope you get cited when they put this dialog in the next movie
5C5C5C@programming.dev 1 week ago
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.
-Ackchyualllllly, they all revolve around the galactic center…-Godzilla floats by increasing his volume.
-Ackchyually, 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…abfarid@startrek.website 1 week ago
Whimsical or not, there was a scientific misconception used the statement, that I 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 will 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.
abfarid@startrek.website 1 week ago
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 bouyancy.
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.5C5C5C@programming.dev 1 week ago
“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.

Ducks and other waterfowl have the majority of their weight above the waterline. So do boats.
