pick related, we'd just need to wear weighted vests to lower our buoyancy outside

the pressure wont crush u retard, because your breathing a in-compressible fluid at the same pressure as the fluid around you there is ZERO pressure difference. this is why fish dont get crushed, because their internal pressure is the same as the external pressure, also for heat exchange just wear aerogel lined clothes. also the currents wont disturb it much because it is much denser than water. as long as there is a few meter high fluid retention walls there will be negligible amounts lost, and zero loss with even the thinnest of plastic sheets over the top

mechanically, how are our lungs able to handle a denser-than-water liquid?

A mouse breathing this shit isn't a human breathing this shit. Stop it with this nonsense. Once there are human trials we can ask this but until we know its possible theres not much point in discussing it

>>12013913
It’s harder than normal breathing, but it’s not impossible, as long as you aren’t exerting yourself massively physically you should be fine and completely fine with mechanically assisted breathing

>>12013927
We’ve already done human studies??? It’s been used a fair few times before?

This is actually the concept behind a book called “Ocean on Top”
A fish tank under the sea filled with breathing fluid denser than water

bruh your lungs and stomach and other innards are literally filled with this cold ass water, doesn't really matter what clothes u wear

Legitimately really cool idea.
Diver here, the main problem you'll encounter with this is cold, however if you heat the fluid using geothermal or nuclear it has a lower heat capacity and should be comfortable. As for trees and stuff though it could be a problem... Remember there's absolutely no light even like 30ft down and normal plants need a lot more to live. Furthermore the oxygen levels must be very carefully controlled as oxygen is a poison at depth. I can only breath pure O2 to about 20ft, and over 150ft you can start to remove it from the mixture. Lastly fluid mixing will be a big deal, EG getting it mixed up enough to ensure that it's homogenous in concentration.
Lastly work of breathing is going to kill you, unfortunately even breathing air feels "thick" at 120ft. Breathing takes work and that work can exert you, since the relative concentration of CO2 increases with depth you can poison yourself if you're working too hard breathing. From what I understand it's too hard to manually breath on the ground. So while this makes dope sci-fi it's probably not possible. Although some freon type molecules are non toxic and may be not thin enough to breath. But an open pit is likely not possible for reasons above. Oh and the oxygen would actually flow into the water layer like it does on land.

What about just sea water? https://sys.4chan.org/derefer?url=https%3A%2F%2Fapps.dtic.mil%2Fdtic%2Ftr%2Ffulltext%2Fu2%2F671793.pdf
At 80 meters And below the pressure is high enough that the saturation point of isotonic saline is high enough u can breathe it like like perfluorocarbon, so we just make some sun thin domes and saturate the water in them with oxygen, maybe some geothermal heating? Apparently co2 retention is an issue but even mice could survive 4 fucking hours, naked mole rats can breathe 10% co2 air so if we modify ourselves a tiny bit we should be fine , sunlight should be fine. Planets will be fine, the only thing is breathing will be difficult but I think adaptable

>>12013908
How would you even get that out of your lungs painlessly?

that's retarded
