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.
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.
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 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.
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.
First, let’s address the expansion of lungs, because you say “little air”, but in terms of volume, lungs are very big. On average, the volume of a human body is about 65 liters. When person fully exhales, the lung capacity is at about 1-1.5L; when expanded, it’s about 5-6L. Interpreted charitably, that’s roughly 8% percent of the entire human body volume. So realistically, expansion of the body by 8% is the difference between slowly sinking, and floating with the top of your skull (or roughly 1% of your body volume) peaking out of water.
Now, Godzilla, on the other hand, has like 80% of his body above water. Can you imagine, the amount of expansion that needs to happen for that much buoyancy? That’s pufferfish territory.
So no, a “tiny percentage” increase in body volume driven by empty chamber “inside” his body would not be enough.
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.
I can’t, and I wasn’t going to. My argument was never about what Godzilla can or can’t do, it was about physics. Specifically, that you can’t move stuff around internally, without changing volume significantly, to change buoyancy.
Deballasting bone cavities is definitely an option. But to achieve the levels of buoyancy displayed by Godzilla, they’d need to be truly massive. Or he’s using paddling in tandem to help itself stay above water, akin to what dolphins do to hold most of their body above water.
Also, you can’t squeeze bones, so Godzilla needs an organ that would force discharge that ballast. Like sacks of highly compressed air, which are used to push out the water completely. This is similar to what submarines do.
Instead of bones, we could also just use your approach with organs. Emptying sacks of water and filling them with air. But either way, we need to discharge ballast, as I was saying originally. It’s a limitation of law of physics, and not a limitation of Godzilla’s abilities.
Source: I have a bachelor’s degree in Maritime Transportation and Navigation. Which is basically a BSc on “how to buoyancy right”.
Don’t know what to tell you, man. You sound very confident, but I literally have a bachelor’s degree in Maritime Transportation and Navigation, and have served on several cargo vessels, as well as a couple of passenger ferries. I might have exaggerated with 90%, I’ll give you that, so take it down to 80%.
cruise ships are 10% underwater
As I said, those are usually mostly above water, to prioritize comfort. But even those are at least 30% underwater, with very low center of gravity. You can’t have a ship 90% above water; it would keel over. Except some heavyweight barges that have big surface area, I suppose.
A fully loaded cargo ship can’t be more than 30%
In fact, that’s about the least an empty cargo ship is underwater. Because when empty, cargo ships take ballast to prevent capsizing. Also the propeller is designed to be at least a few meters below water to be effective.
they tend to be stacked far higher than the ship’s sides
I think you’re focused specifically on container vessels. Those still have way more massive holds than the containers you see on deck.
Ocean waves would easily swamp a ship that was 80-90% underwater
Depending on the season and projected weather conditions, ships are leaded to a different extents. They have load lines for winter and summer. In summer, for certain cargo ships, the freeboard can sometimes be measured in centiliters. I remember being able to kneel on deck and reach the water with my hand. In heavy seas, the waves are constantly on the deck and the ship can handle it fine; you just don’t go there.
Ships often look deceptive about their draft, because you almost never see a ship truly empty. Even when not carrying load, they have a lot of ballast.
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.
But this “unprocessed salami” can speak. Kinda puts them on level playing field.
Unless, of course, salami is voiced by Eddie Murphy, in which case it’s an easy pick.
That’s a shame there aren’t any players any more.
I’m a patient gamer, too. I almost never buy games at full price. But I try to strike a balance with online(-ish) games. Some experiences you just can’t have once a game with an online aspect isn’t popular anymore.

They don’t, actually. Most of AI stuff is processed on device, few go to their private infrastructure, and only certain Siri requests go to ChatGPT, if you give explicit permission.
It’s weird to assume that OS doesn’t “read” the notification content, because how else would it categorize them by priority, and provide smart replies and stuff.
Based on their claims Siri also works primarily on-device. It wasn’t entirely clear if you can manually prevent the usage of their AI infrastructure, but they definitely implied it. So if that’s true, there’s no real reason to avoid just Siri while still using other AI stuff, cause they are one and the same. And since it runs locally, they can’t even store the voice clips.
I’m pretty sure it wasn’t on-device before. At least not all the time. But I have some good news for you, they added the ability to type your requests to Siri 😆
And to be fair, some certain things are definitely faster by voice than doing manually, like setting a timer and stuff. It’s just daunting when the assistant misunderstands you or takes ages to respond. If they fixed all that, it could actually be useful.
Not really, it can make sense. By “reading” your messages/notifications they could just perform semantic search/categorization, or now, run a local LLM. It doesn’t necessarily mean they send that data to servers or make people actually read it.
Encryption just means the data stored on your device is not saved in plaintext. So if somebody gets their hands on your phone, they won’t be able to hot-wire the memory chip and directly read all the data.
If it’s the encrypted transfer protocols that you’re talking about, then it’s just for the transfer of data. It was never meant to make things secure on the endpoints. Encrypting your whatsapps, signals and so on just ensures the ISPs and mobile operators can’t read your messages. Also prevents an occasional MITM attack. Once the data reaches your device it’s not encrypted anymore, as you can read it and copy it.
I don’t follow. No I don’t think that most people think that Apple and Samsung are spying on them. But a lot of people are concerned about NSA and the likes having access through the cellular service. Which is what the encryption is for.
Yes, but Gemini is pretty bad. The only thing it has going for it is the half-assed Google integration. Can read your emails, but not your calendar…
Well, I guess the large context window, too, but when the model itself is bad, it’s doesn’t matter much if it has massive context.
The reason why you’re being downvoted here is beyond me. Surely, everybody understands, that vast majority of politicians are “for sale”, and maybe only a handful of them have any decency at all.
I know I’m being pedantic, but that’s the word used in the video and that’s the slang term, specifically “bike”, probably because it sounds more punchy.
Ultimately, both of those commenters are annoying. Saying “I use Arch btw” is a useless self-serving statement that provides no benefit or information to the audience. But engaging with that message in the manner displayed is also pointless and stupid, even if the statement is correct.
The saving grace for the “Linux user” commenter is that they are self aware about being annoying, judging by their last comment. So hopefully they were just being ironic. Or rage baiting.
I checked the video and found the comment. Commenting about using Linux on that video is the equivalent of finding a turkey recipe and commenting “No thanks, I’m a vegan” on it. Then why did you open this video?!
I totally understand the overall ridiculousness of this, but I suspect that “mandatory” and “voluntary” apply to 2 different people in this case. Person 1 has a “mandatory shift” and person 2 is supposed to voluntarily cover that person’s mandatory shift.
