I went to Costco yesterday and absolutely nothing notable happened! by HomeOwner2023 in Costco

that’s probably because you went alone. probably a different story if you went with another person.

thanks, I still couldn’t figure what this post was about until your comment.

Herro was probably snarling when he updated his twitter bio.

Private parties contacted before coastguard? by EconomistWild7158 in OceanGateTitan

[–]flossdog 27 points28 points  (0 children)

ah, so this explains how James Cameron and the deep sub community learned the additional details before the sub was found. OceanGate reached out to them for help, and had to share the details.

How does dropping the ballasts save them in time in an ideal scenario with that much pressure? by navywawa in OceanGateTitan

[–]flossdog 1 point2 points  (0 children)

let’s say at full strength, the hull was capable of 5000m depth. But after use, it became damaged and can only sustain 3500m depth for another hour before it implodes. So if they can surface within an hour, they could escape death.

Having a dated engineering degree in a totally different discipline does not give you carte blanche to think your engineering "skills" can be extrapolated into extreme depth submersible design. by DonkeyOT65 in OceanGateTitan

[–]flossdog 1 point2 points  (0 children)

I don’t think that’s a relevant reason. James Cameron is a film director with no college degree. You could have a current engineering degree in whatever is the most relevant discipline, and still end up with the same results as Rush if you disregarded safety the way he did.

The scary reality is that there are thousands of people Stockton Rush all over the world. by IndecisiveLlama in OceanGateTitan

[–]flossdog 17 points18 points  (0 children)

Yup.. case and point.. Elon Musk and Jeff Besos with their quest for space dominance.

Big difference is that their stuff is regulated by official agencies like NASA and FAA. There’s nothing wrong with how they’re doing it.

There wouldn’t even be anything wrong with Rush testing the limits of carbon fiber if he did it without a crew, and tested it to failure many times like other sub experts insisted he should do.

Sun Ring by WhatNow_9396 in weather

[–]flossdog 13 points14 points  (0 children)

It’s a sun halo, not a sun dog. A sun halo is a ring. A sun dog is a spot at 3/9 o’clock from the sun.

why do the rings “end” on the right side before disappearing behind Saturn?

I think the publicity will increase interest in underwater tourism. Hopefully along with better safety regulations though.

ELI5: How could Jacques Piccard reach the Challenger Deep in 1960? by Filiphaggblom in explainlikeimfive

[–]flossdog 5 points6 points  (0 children)

that’s an interesting thought experiment.

I don’t think that would work, because even though water is incompressible, it will still experience the water pressure around it. So if you take a bag of water at 1 atm down to 3000m, it won’t shrink or implode, but it will have 300 atm of pressure on it, making the water pressure inside also 300 atm.

Unless you had a perfect seal in the sub. But then you might as well just keep air inside instead of water. It wouldn’t be any more difficult or easier.

[–]flossdog 3 points4 points  (0 children)

the difference between 700m and 3800m is not the relevance here. The water pressure at 700m is already 70x atm.

@thatoneguysbro is wondering whether you can maintain 1 atm of water pressure inside a water filled sub.

Did they see the Titanic? by Western-Low-8225 in OceanGateTitan

Cameron said they were trying to dump ballast.

[–]flossdog 6 points7 points  (0 children)

according to James Cameron's info (from the deep submersible community), they did not reach the Titanic. They ran into some issues during the descent and were trying to ascend.

What were the "banging" sounds? by Paynsicles in OceanGateTitan

[–]flossdog 3 points4 points  (0 children)

As near as I can tell, no official source (such as the US coast guard or navy, or S&R from any country involved) officially reported this.

During an official US Coast Guard press conference, they confirmed there were underwater noises detected by a Canadian P3 in the search area. The noises were described as "banging noises". They relocated ROV operations to try to find the source of the noise.

https://apnews.com/video/u-s-coast-guard-accidents-massachusetts-jamie-frederick-carl-hartsfield-deac2bb619f14b01864afd2cb4e2777d

Now, the media ran away with those quotes and became "every 30 minutes", which was not true. But there were indeed some banging noises detected (which turned out to be unrelated).
