Firstly: not a sub

Secondly: it's not a rule. People only think it is.

I can see that you're new to the Internet. Welcome!

In this state, you need a permit to shoot.

Option 1: be ugly af but talk normal.

Option 2: be ugly af and talk like complete fool.

Tough choice...

I don't get this article.

The headline says Canada is calling the bluff. Nowhere in the article does it say where Canada actually stand in this issue. No comment about Canadas actions at all. Granted, their inaction could be perceived as "calling the bluff". But if so, say it!

The last words of the article says "if Canada calls Meta's bluff". What?! Did they or didn't they?

Same line break on my screen. Thanks, that's one more thing to blame.

Turns out I'm to drunk to read. Sorry, I misread the headline. Man, I hate english writing words separately...

Nope. The air pressure on the inside of a submarine is close to ~1 bar = ~1 atmosphere.

No? It's the hull of the vessel that counters the outside pressure. The main reason to use a submarine, instead of scuba diving, is to shield yourself from the pressure. If the inside pressure was even close the the outside, which it would have to be to keep it from imploding, you wouldn't need the submarine at all; you'd be crushed regardless.

At the depth of the Titanic, roughly 4000 m, the water pressure is ~400 bar. The record for highest survived air pressure is around 70 bar. That was for 2 hours, breathing a special gas mixture of 99,5% hydrogen and 0,5% oxygen.

I find it highly unlikely that they'd rely on the inside air pressure for anything other than the comfort of the passengers.

"catastrophic loss of pressure"?

Wouldn't it be a catastrophic increase of pressure? They were at the bottom of the ocean.
