Don’t forget we’ve put more people into space than have been to the deepest point on the planet.

Fun fact, space is easier. It takes more effort to get there, sure. Coming from the "normal pressure" here on earth (about 1 atm) and going to space (0 atm) is a pressure difference of 1 atm. But: Diving into the ocean, the pressure increases the deeper you go. For every ~10 meters (~33ft) you go deeper, the pressure increases by 1 atm.

That means, that a space ships would only need to dive 10 m deep to get to the pressure difference it experiences in space. They went to see the Titanic which is about 3,800 m deep. So the sub needs to withhold a pressure difference that's about 380 times higher than a space ship experiences.

(OK, little difference I omitted: In space you need to prevent the vehicle from exploding, while in the deep sea you need to prevent it from imploding)

The atmospheres of pressure gag on Futurama is still one of the best that show ever did.

Here is an alternative Piped link(s):

Yup, it’s part of why the idea of rescuing them was never going to happen either. There’s only something like 3 subs in the world that can dive to that depth and they weren’t close enough nor built for rescue missions. Even if they were alive they only had 3 days worth of oxygen. Honestly they’re lucky that the “sub” just imploded rather than dealing with the slow loss of oxygen.

I'm not sure about that, hypoxia could be a fun time. CO2 poisoning would just be sleepy... So not as fun I guess. Waiting to die would definitely be lame though.

Try again. High CO2 is highly uncomfortable. You cannot catch your breath, headaches, confusion, body has to deal with blood trying to go more acidic... CO2 poisoning is anything but a nice nap.

Exactly. Your lungs don't burn when you hold your breath because O2 is low, they burn because CO2 is high. Any other gas to displace the O2 is undetectable (aside from irritants and smells). It's why huffing helium doesn't burn but can make you light headed faster than you realize. That's why CO poisoning is so dangerous. CO2 poisoning is torture. And yet CO2 pits are still legal for kill pits...
