Looks like The Titanic killed a few more people

they can often refute an article with faulty reasoning, or add to it in greater detail.
The other alternative is varying degrees of batshit cray cray theories or completely unrelated diatribes.
Avoiding them is not a bad policy 😀

Probably would have scared the living daylights out of everyone who stepped on that thing.

You wouldn't have liked a ride on a pre Trident sub then. They didn't have nice rubber doughnuts suspending the deck floors, just metal to metal slip joints. The hull contracts, just tie a string across the hull tight before you go down, it will sag as you go deeper.

Fact Check: Did Titan implosion cause vessel to become as hot as the sun?

The deep-sea submersible experienced a "catastrophic implosion" during a voyage to the wreck of the Titanic.

I don't understand that fact check. It talks about "friction" as a cause of heat, and dismisses it
"The collapse of the composite or metal structure would just produce theoretical heat energy due to friction, but this is very low and would not be visible or measurable with the mass of cold water around it."

...but I thought the claim was about the heat due to adiabatic compression of the air in the sub. That's a different thing from "friction" due to the collapse of the structure.

Basically the professor they quote in that 'fact check' doesn't address the actual argument. Seems to me to be quite plausible to argue the air would have experienced rapid intense heating...but may well be there's a counter-argument, just that article doesn't offer one.

As was suggested to me earlier, read the comments. 🙂

Having read the comments, I feel like I know less about what happened than I did when I started! Completely confused now. The guys saying it's not adiabatic becuase 'the gas can escape' are clearly wrong, as the gas would be compressed in every direction by the water pressure. And arguing that heat would be lost to conduction and radiation in the water doesn't really say much unless one knows how long that process would take - could still reach very high temperatures for a very short period.

The argument that some of the energy is dissipated in shock-waves is hard to dispute, but also beyond my capacity to quantify. Maybe it's something one would have to perform an empirical test to know for sure?

High speed camera with high speed relay to external storage (outside of the craft). Send it on down and wait for the pop.

Cameron spoke of a timeline where they had dropped the ballast to head to the surface, and then went silent.
I don't have any illusions that they had no warning either. ^

That's a guess on his part though. They lost contact before reporting that.

Yeah, it'd happen so quickly it'd effectively be adiabatic. We use an adiabatic compression assumption on hydraulic accumulator gas and it very closely matches reality, and compared to an implosion, that's relatively slow.

Yeah those women have some nerve

Peep show on the Wyoming

"Up to a dozen sailors are suspected of viewing secretly recorded videos of their female shipmates undressing in a submarine shower over a period of 10 months, according to a new investigative report obtained by Navy Times. The scandal has marred the Navy's gender integration effort begun four years ago. While it appears only one sailor has been implicated in the videos' production and distribution, 11 are suspected of watching them and failing to report the matter to their commanders."

If the womens hadn't been on the sub the men wouldn't have been tempted. It's the womens fault for wanting to serve in the first place, men folk just can't be trusted because reasons.
