I would disagree, considering that "space" is infinite. I'd say we've explored perhaps 0.00000000000001% of known space. If even that much. We've basically been to the moon and Mars... and it wasn't even people that went to Mars.
It depends on what you mean by "space". I mean, what do we know about what's under the ice of Europa? What do we know about the details of extrasolar planets, many of which may have their own oceans? If you look at space in a very coarse-grained way and the ocean in a very fine-grained way, then the statement is true, but if you compare our knowledge of each in detail it's clearly false. I wish I could remember the exact quote about an astronomer being asked about how after all their research they still didn't fully understand something as simple as a star. The apocryphal reply was "From 50 light-years away, you'd look pretty simple too."
Your blood has dissolved inert gasses in it, after being under high compression, when decompressing (entering into an area of lower pressure), these gasses can come out of solution to form bubbles in your bloodstream if you decompress too quickly. These bubbles can travel in your bloodstream all over the body and cause a wide variety of issues, from minor nuisances to extremely deadly complications. People who dive down that far usually have to come back up slowly, so that thee pressure can ease up gradually.
Thanks, I would add... 'Think carbonated beverage" where the gas is Nitrogen instead of CO2 and the beverage is the blood. The Nitrogen (being the most abundant gas in our atmosphere) is pressurized to the same pressure as the water pressure at depth to allow you to take a breath against that outside pressure. The side effect is that the Nitrogen dissolves into the blood slowly and will come back out of solution slowly. Take the pressure away (surface too fast) and imagine a shaken carbonated beverage in your veins and arteries. Painful and deadly. They refer to the disease as 'the bends' because of the excruciating pain this causes.
@@scottdebruyn7038 The other problem diving deep causes is Nitrogen Narcosis. This is where the air you are breathing (21% Oxygen / 78% Nitrogen) at this pressure becomes narcotic, in effect it's like getting drunk, which being mentally impaired underwater is the last thing you want to be. People have reported it seems to start around 90 feet, but some people go somewhat deeper before noticing the effect. Interestingly just going up 10-15 feet the effect seems to reverse, probably because the extra nitrogen can leave the body much faster through the lungs than alcohol can through the liver. For much deeper dives they use a Helium/Oxygen mixture to eliminate the narcosis problem.
you all prolly dont give a damn but does someone know of a trick to log back into an Instagram account..? I somehow lost my login password. I appreciate any tricks you can give me!
the best way to describe what compression sickness ("the bends" or "caissons disease" as it was originally known) does to the human body would be to take a can of soda, shake it up, and then open it. what happens with the fizzing of the soda is the same thing that happens to all the blood in your veins and arteries.
When you ask how fish can survive that deep, they almost fall apart when you bring them to the surface. Their bodies are designed for that high pressure, so for them, our world is like going in to space without a suit if you just pull one up.
yeah... I remember my brother fishing up a deep sea creature and it started to harden then crumble like sand after a while. Not sure what kind of creature it is, it looks like a very small eel at the very least.
Decompression sickness, or “the bends” as it is sometimes called occurs when you go from a deep and high pressure environment to a higher up and lower pressure environment too quickly. What happens is that your body, and more specifically your blood and other fluids have gasses dissolved in them. At high pressures, the gasses dissolve better into your tissues. The issue is that if you go from this high pressure zone to a low pressure zone too quickly, all those gasses in your blood, brain fluid. Etc. come out of solution, meaning that your blood literally starts boiling and releasing bubbles of nitrogen, oxygen and co2 gasses into your arteries. Gas bubbles in your arteries can lead to hemorrhaging, strokes, and often cardiac arrest. These symptoms are what usually results in death from compression sickness. So....yeah, changing pressure too quickly causes your blood and body fluids to bubble like a can of soda. That is obviously a very bad situation and leads to a plethora of health issues. This is why it’s so important for divers to ascend from dives incredibly slowly and gradually to allow time for the gasses to slowly get redistributed

I think decompression sickness has to do with the oxygen in your blood. I was under the assumption that it happened when you were coming back up, which is why scuba divers have extra tank for the decompression and they come up in stages so they don't get decompression sickness.
Decompression sickness, also known as "the bends" happens when you ascend to rapidly. As a general rule you should not surface any faster than the bubbles you breath out. This gives your body a chance to exhale the excess gasses dissolved in your blood stream. Ascend to rapidly, and the same thing happens in your blood as happens when you pop the top off a soda bottle, resulting in severe pain, and possible death. The problem gas is nitrogen. This is why deep divers use helium to replace nitrogen in their air tanks. I'm not a diver, but I have seen documentaries. If you do get the bends, treatment is in a hyperbaric chamber where air pressure can be applied to get the gas bubbles to dissolve again, then bring the pressure down slowly enough that your body can get rid of the excess without having the bubbles reappear. If you wish to know more, or find out if I've made an error, you should be able to find this information with a Google search.

I think you also can have the effect of feeling drunk and lethargic in really deep water not sure if that’s decompression or something else tho (might be the effect that breathing in pure nitrogen has after a certain period of time
Please stop saying you’re stupid. The fact that you’re learning from these videos, and want to learn proves that you’re quite intelligent. The lack of knowledge is only ignorance and ignorance has nothing to do with intelligence. I too was ignorant about how truly deep the oceans are before watching this video. Never stop learning.
3:00. Decompression sickness is essentially nitrogen bubbles forming in your blood. It's a lot like what happens when you crack open a soda can. Your blood becomes pressurized, allowing extra gas to enter your bloodstream. When you go back up and depressurize your blood, that extra gas cannot stay. Your body can only let so much gas out of your blood at once, so if you go up too fast the extra flow will pile up in your bloodstream as bubbles, which can be very dangerous.
Titanic sank off of the coast of Newfoundland and Labrador. If you have, or wish to download, Google Earth, you can actually find a 3d model of the ship in the general area of where it sank. You can also visit the Challenger Deep as well.
So true. They might talk about this in the video, but Mauna Kea in about 14,000 ft above sea level here in Hawai’i...and it’s so tall that we get snow every January. But that’s only about 1/2 the height of Mount Everest. However, if you measured Mauna Kea from the sea floor...it’s taller than Mount Everest.
But many people forget that when you stand on any land you’re basically standing on a mountain that was high enough to reach out of the ocean... Once you hit the coast, maybe the slope down to the bottom is very long and gentle (like at swimming beaches) or maybe it’s an underwater cliff edge, but the raw elevation is there no matter what And then the ocean floor has canyons and chasms just like dry land does
decompression sickness is basically when after going deep down into the water with a lot of pressure, you try to swim up back to the surface too fast. you have to do it slowly to allow your body to adjust back to normal pressure.
At high pressure, gas is compressed into liquid, which is blood in this case. This happens gradually as divers descend. When divers then ascend too quickly, the liquid which had been compressed turns back into gas too quickly and the amounts of gas in your blood can be dangerous.
decompression sickness (also called the bends) is when your body starts putting nitrogen bubbles into your bloodstream as you descend into the ocean. if you do not ascend slowly and allow the bubbles to dissipate the nitrogen bubbles can rupture can cause aneurysms.
Even though humans got a head start on oceans vs. air/space, the logistics involving oceans get more complicated once you scratch the surface. (heh heh) Suggestion: Wendover Productions: "How Aircraft Carriers Work"
decompression sickness is caused when you dive too deep too fast and rise back up too fast. Basically, your body has to go down and come up slow so that it can regulate the changes in pressures. If you rise too fast the change in pressure in your lungs and organs can cause them to rupture.
Decompression sickness is when bubbles of nitrogen form in your bloodstream. As you dive the pressure dissolves nitrogen into your blood as you ascend that nitrogen turns into bubbles causing the bends. You avoid this by slowing ascending the only problem is you don't have enough oxygen to do that. You can be put in a pressure chamber or iron lung to combat this but those aren't readily available.
Thinking about the vast deep space and all we haven't see is one thing, and then you think about the oceans, and ALL we don't know and haven't seen yet. And it's right here. This is our home.
If I remember correctly, the deeper you are, the more pressurized the air is in your lungs & blood, so the sickness comes from air bubbles growing in your blood due to the huge pressure change when you come up too fast. The treatment is to put the person in a small room, pressurize it to about the equivalent of that depth, then slowly reduce the pressure.
In the deeper parts of the ocean, the water pressures are so deep that it actually changes the shapes of molecules such as oxygen. This means that the pressures actually change how chemistry works. This is a big part of why so many deep sea creatures die while being pulled to the surface when caught. Decompression sickness, also known as "the bends", is caused by nitrogen from the diver's air tanks, that has been diffused into the blood stream under pressure, suddenly turning back into gas within the diver's tissues. This is the same thing that happens when you open a "fizzy drink" or soda.
Decompression sickness, otherwise known as The Bends, because the effects are crippling and sometimes deadly, happens because with a rapid ascent, the sudden lack of pressure causes Nitrogen bubbles form in the blood. My grandfather was a Sponge Diver in Greece. He was not afflicted himself, but many of his colleagues were. When I was young, you would still see old men who had gotten the bends, walking with canes completely bent over and crooked. 😪
One that I highly recommend is the Boston molasses flood of 1919 there is a good video disasters of the century a docudrama from the early 90s that’s really good
Decomposition sickness is when the nitrogen in your blood gets forced into your joints and organs under pressure then if you surface too fast it expands and causes blots of problems up to death
You know how when you first open a bottle of a carbonated drink all the bubbles appear and start fizzing? Decompression sickness is when your blood does that due to the rapid change in pressure if you come up to the surface from a deep dive too fast
With decompression once you get to a certain point in the water you have to stop and equilibrate for 10-30 minutes before going any deeper. If you don’t do that your body will basically once out of water expand tremendously. There’s photos online if you look them up of people who have had this happen to them and the only way to reverse it is if right once you get back on land you have to go in a air compressed chamber and lay in it for a long time. Otherwise the results are irreversible
If you breathe in under water, you have to basically push pressurised air into your lungs, because the weight of the water pressing down on your chest would not allow you to take a full breath. That means, your whole body becomes pressurized to the same pressure as outside. If you rise back to the surface too quickly, the gases dissolved in your blood will basically bubble out like a bottle of soda. So, like with the shaken bottle of soda, you have to release the pressure bit by bit or you got soda in your face.
You should react to some of the show "I Survived". One of the episodes has this guy giving a detailed first-person description of his experience getting caught out in a Tornado. His story's intense; it's really wild
We do know more about space than our own ocean the reason is it's easier to withstand low pressure vs high pressure. Think of it this way if you go to the bottom of the Mariana trench the pressure you would experience is 15,750psi or 1072 Atm your suit or sub would have to withstand a pressure that is 1,071 times the pressure you normally experience on the surface which is 1 Atm or 14.6 psi. in space there is no external pressure so the suit or ship only has to withstand normal atmospheric pressures within them which is much easier to do.
Water pressure sickness is dangerous because (as far as I know) water pressure can mess with your blood pressure, the oxygen getting to your brain, and even bones and muscles getting crushed. There might be more than that but, That's all I know. Any professionals who see this, please correct me if I'm wrong bout something! Thanks
Decompression sickness: a condition that results when sudden decompression causes nitrogen bubbles to form in the tissues of the body. It is suffered particularly by divers (who often call it the bends ), and can cause pain in the muscles and joints, cramps, numbness, nausea, and paralysis.
To give you an idea of how big Earth is, from the surface to center of Earth is almost 6,378,137 meters. If all the water was removed from the planet, it would be relatively smooth, like a billiards ball you had rubbed with sandpaper.
It’s even more amazing for the Sperm Whales...imagine going down 2.25 KILOMETERS on a SINGLE BREATH, ‘cause unlike the Colossal Squid, Sperm Whales have to breath air.
9:49 that's terrifying if you think about it like what is in the unknown like how deep is it or even what's in it we don't know and that makes the sea scary
Yea, at that depth if the windows completely failed you wouldn’t have to worry about being able to swim. No, the “S-word” you’re looking for in that scenario is “squish.”
Now consider the surface of the earth is smooth enough to play billiards with, if it were shrunk down. Despite all the mountains and the depth of the ocean, Earth would still roll fine with no wobbling.
One video you should watch is the Battle of Midway tactical overview on UA-cam. It was the battle where the American navy got revenge for Pearl Harbor and put the Japanese on the defensive for the rest of the war.
Well, really we know almost nothing about the ocean OR space. But yes I think we know a bit more about space. It is, after all, easier to observe since light can get to distant objects in space thus we can use telescopes and cameras and such. But one thing you’ll learn is that we just don’t know much about science at all. The amount of science that exists already discovered is so huge one can’t even imagine it, but it’s estimated to be only like 1% of all the potential scientific knowledge that is discoverable. We also know less about our own brains than we do about space.
If you ever find yourself flying away in space, throw something in direction opposite the way you want to go. Should work, if Space Station 13 is to be believed.
You don't explode from Decompression sickness but it can kill you if it is severe enough.The Titanic is in the north Atlantic. The Ocean is almost as alien as space and practically as hostile for different reasons.
From our perspective it's deep. From the Earth's perspective it's almost nothing. The Earth's surface is smoother than a cue ball. Seems crazy to us because we're little mites that see huge mountains, craters, canyons, etc., but if you shrunk down to scale with a cue ball as we are to the Earth, there'd be cracks that make the Grand Canyon look like nothing.
Decompression sickness from my limited understanding... The deeper you go the longer it takes to come back up, not because it's physically challenging, but because coming back up too quick will cause the pressure in your body to change way too quickly. For peeps that dive in deep sea submarines, they have to wait for the submarine to slowly pressurize... And when they come back up, they spend hours in a decompression chamber. Pressure is not to be taken lightly... Without proper safety procedures, or caution, people can, and have died.
It's weird to think about since it's all inside your body and equipment, but the deeper you are in the ocean, the more air you have in each breath. Don't quote me on the ratio here, but I think it would be something like - twice the pressure would mean twice as much gas in your lungs, it's just, at twice the pressure, it's taking up the same space as a normal breath would at normal, surface pressure. If you picture your lungs as a balloon, picture filling it down at 4x pressure. You fill the balloon to a normal looking size, then head back up to the surface. The balloon has 4 atmospheres of pressure, but the water around it will gradually become less and less of a counter. At some point, the water pressure outside the balloon isn't enough to keep the gas inside compacted, and it will pop. Essentially, your normal looking balloon at depth would become a regular balloon filled with 4 times the air at the surface.
I have severe thalassophobia, the fear of the ocean and deep water. This video, when I watched it, just further fueled my fear. I can't do cruises, I'd freak the fuck out. Scuba diving? Forget that. Anything that goes underwater more than ten feet, nooope. If I were to be stranded in the middle of the ocean, I'd lose my shit. I hate it with a passion.
The James Cameron mentioned in this video is the same James Cameron who directed films such as Avatar, Terminator, Titanic, and Aliens

Once you hit the coast, maybe the slope down to the bottom is very long and gentle (like at swimming beaches) or maybe it’s an underwater cliff edge, but the raw elevation is there no matter what
And then the ocean floor has canyons and chasms just like dry land does
I love how you were shocked that people went 10,000 metres, but how would we know all the information down there unless people have been? XD
Very good point 😂😂
Eh, robots. Lol
The same way we know about mars and many other places we have never been.
Okay yeah I had a brainfart. I forgot about technology 😂😂😂

No worries. We all have to let it out sometime. 💨😉
decompression sickness is basically when after going deep down into the water with a lot of pressure, you try to swim up back to the surface too fast. you have to do it slowly to allow your body to adjust back to normal pressure.
8:15 good thing James Cameron is a film maker
The ocean is terrifying.
So deep and dangerous..and so many nasty beasties.
At high pressure, gas is compressed into liquid, which is blood in this case. This happens gradually as divers descend. When divers then ascend too quickly, the liquid which had been compressed turns back into gas too quickly and the amounts of gas in your blood can be dangerous.
People often say "we know more about space than the ocean at only 5%", but we know 0% about space...
decompression sickness (also called the bends) is when your body starts putting nitrogen bubbles into your bloodstream as you descend into the ocean. if you do not ascend slowly and allow the bubbles to dissipate the nitrogen bubbles can rupture can cause aneurysms.
Even though humans got a head start on oceans vs. air/space, the logistics involving oceans get more complicated once you scratch the surface. (heh heh)

decompression sickness is caused when you dive too deep too fast and rise back up too fast. Basically, your body has to go down and come up slow so that it can regulate the changes in pressures. If you rise too fast the change in pressure in your lungs and organs can cause them to rupture.
Decompression sickness is when bubbles of nitrogen form in your bloodstream. As you dive the pressure dissolves nitrogen into your blood as you ascend that nitrogen turns into bubbles causing the bends. You avoid this by slowing ascending the only problem is you don't have enough oxygen to do that. You can be put in a pressure chamber or iron lung to combat this but those aren't readily available.
Thinking about the vast deep space and all we haven't see is one thing, and then you think about the oceans, and ALL we don't know and haven't seen yet. And it's right here. This is our home.
i had a dream u did this. dont ask why i have u in my dreams
I'd be ok with him visiting me in my dreams too
😋
Yeah but 1% of space is still trillions of times more stuff to learn than 5% of the ocean lmao...
If I remember correctly, the deeper you are, the more pressurized the air is in your lungs & blood, so the sickness comes from air bubbles growing in your blood due to the huge pressure change when you come up too fast. The treatment is to put the person in a small room, pressurize it to about the equivalent of that depth, then slowly reduce the pressure.
In the deeper parts of the ocean, the water pressures are so deep that it actually changes the shapes of molecules such as oxygen. This means that the pressures actually change how chemistry works. This is a big part of why so many deep sea creatures die while being pulled to the surface when caught.
Decompression sickness, also known as "the bends", is caused by nitrogen from the diver's air tanks, that has been diffused into the blood stream under pressure, suddenly turning back into gas within the diver's tissues. This is the same thing that happens when you open a "fizzy drink" or soda.
Decompression sickness, otherwise known as The Bends, because the effects are crippling and sometimes deadly, happens because with a rapid ascent, the sudden lack of pressure causes Nitrogen bubbles form in the blood. My grandfather was a Sponge Diver in Greece. He was not afflicted himself, but many of his colleagues were. When I was young, you would still see old men who had gotten the bends, walking with canes completely bent over and crooked. 😪
If you wanna take a look at the pressure thing... the blowfish doesn't look like a blob when it is at its normal depth
RMS TITANIC is two and half miles down.
One that I highly recommend is the Boston molasses flood of 1919 there is a good video disasters of the century a docudrama from the early 90s that’s really good
The lack of yards next to the meters has me sitting here with no idea how deep any of this actually is. But there's big numbers...so it sounds deep.
Decomposition sickness is when the nitrogen in your blood gets forced into your joints and organs under pressure then if you surface too fast it expands and causes blots of problems up to death
You know how when you first open a bottle of a carbonated drink all the bubbles appear and start fizzing? Decompression sickness is when your blood does that due to the rapid change in pressure if you come up to the surface from a deep dive too fast
Decompression sickness is when nitrogen bubbles form in your blood if you return to the surface too quickly after going down to a great depth
Decompression sickness is the expansion of nitrogen in your blood if I'm not mistaken. Also called "The Bends"
Decompression Syndrome also known as The Bends, or Caisson Disease, excruciating pain from gas bubbles in your blood.
6:34 Recently found pictures of the Titanic just before it left port suggest it's coal reserves were on fire.
With decompression once you get to a certain point in the water you have to stop and equilibrate for 10-30 minutes before going any deeper. If you don’t do that your body will basically once out of water expand tremendously. There’s photos online if you look them up of people who have had this happen to them and the only way to reverse it is if right once you get back on land you have to go in a air compressed chamber and lay in it for a long time. Otherwise the results are irreversible
If you breathe in under water, you have to basically push pressurised air into your lungs, because the weight of the water pressing down on your chest would not allow you to take a full breath.
That means, your whole body becomes pressurized to the same pressure as outside. If you rise back to the surface too quickly, the gases dissolved in your blood will basically bubble out like a bottle of soda. So, like with the shaken bottle of soda, you have to release the pressure bit by bit or you got soda in your face.
You should react to some of the show "I Survived". One of the episodes has this guy giving a detailed first-person description of his experience getting caught out in a Tornado. His story's intense; it's really wild
Discovery Channel has show called "Draining the oceans" that is somewhat overdone but pretty cool. You can find them online.
We do know more about space than our own ocean the reason is it's easier to withstand low pressure vs high pressure. Think of it this way if you go to the bottom of the Mariana trench the pressure you would experience is 15,750psi or 1072 Atm your suit or sub would have to withstand a pressure that is 1,071 times the pressure you normally experience on the surface which is 1 Atm or 14.6 psi. in space there is no external pressure so the suit or ship only has to withstand normal atmospheric pressures within them which is much easier to do.
Water pressure sickness is dangerous because (as far as I know) water pressure can mess with your blood pressure, the oxygen getting to your brain, and even bones and muscles getting crushed. There might be more than that but, That's all I know.
Any professionals who see this, please correct me if I'm wrong bout something! Thanks
Decompression sickness:
a condition that results when sudden decompression causes nitrogen bubbles to form in the tissues of the body. It is suffered particularly by divers (who often call it the bends ), and can cause pain in the muscles and joints, cramps, numbness, nausea, and paralysis.
To give you an idea of how big Earth is, from the surface to center of Earth is almost 6,378,137 meters. If all the water was removed from the planet, it would be relatively smooth, like a billiards ball you had rubbed with sandpaper.
It’s even more amazing for the Sperm Whales...imagine going down 2.25 KILOMETERS on a SINGLE BREATH, ‘cause unlike the Colossal Squid, Sperm Whales have to breath air.
"Hey, James. You wanna be a Revolutionary Deep Sea Explorer or One of the most famous, biggest Film makers ever?"
Jame Cameron: Yes
9:49 that's terrifying if you think about it like what is in the unknown like how deep is it or even what's in it we don't know and that makes the sea scary
also to think about involving the titanic its sunk such a deep amount it could have drifted vast distances past where it initially sunk
Yea, at that depth if the windows completely failed you wouldn’t have to worry about being able to swim. No, the “S-word” you’re looking for in that scenario is “squish.”
Now consider the surface of the earth is smooth enough to play billiards with, if it were shrunk down. Despite all the mountains and the depth of the ocean, Earth would still roll fine with no wobbling.
One video you should watch is the Battle of Midway tactical overview on UA-cam. It was the battle where the American navy got revenge for Pearl Harbor and put the Japanese on the defensive for the rest of the war.
Well, really we know almost nothing about the ocean OR space. But yes I think we know a bit more about space. It is, after all, easier to observe since light can get to distant objects in space thus we can use telescopes and cameras and such. But one thing you’ll learn is that we just don’t know much about science at all. The amount of science that exists already discovered is so huge one can’t even imagine it, but it’s estimated to be only like 1% of all the potential scientific knowledge that is discoverable. We also know less about our own brains than we do about space.
Fun fact about the Titanic depth. the water pressure is so strong it literally crushes bone
Whats crazy is the guy who made the movie titanic and avatar is the top deepwater explorer.
Decompression sickness isn't the pressure itself killing you lol
It's air bubbles forming in your blood
Titanic sank in North Atlantic , 400 miles south of Newfoundland, Canada. Real cold
Joseph Vincent has been dropping some bangers lately, especially the one about Derrick Henry
If you ever find yourself flying away in space, throw something in direction opposite the way you want to go. Should work, if Space Station 13 is to be believed.
You should react to: How 1 Man Survived Being Lost 438 Days at Sea... Its also by RealLifeLore ;)
great video btw
The Mariana Trench is even deeper and he didn’t mention it! It is 11,034 Meters Deep!!!
I recommend you react to some famous speeches. Tried times we are in and would be great to see!
Idk why but I want to hug you, no homo
I’m glad your channel is doing well, you deserve it for sure. keep being you yo fr 🔥❤️
You don't explode from Decompression sickness but it can kill you if it is severe enough.The Titanic is in the north Atlantic. The Ocean is almost as alien as space and practically as hostile for different reasons.
From our perspective it's deep. From the Earth's perspective it's almost nothing. The Earth's surface is smoother than a cue ball. Seems crazy to us because we're little mites that see huge mountains, craters, canyons, etc., but if you shrunk down to scale with a cue ball as we are to the Earth, there'd be cracks that make the Grand Canyon look like nothing.
Decompression sickness from my limited understanding... The deeper you go the longer it takes to come back up, not because it's physically challenging, but because coming back up too quick will cause the pressure in your body to change way too quickly.
For peeps that dive in deep sea submarines, they have to wait for the submarine to slowly pressurize... And when they come back up, they spend hours in a decompression chamber. Pressure is not to be taken lightly... Without proper safety procedures, or caution, people can, and have died.
It's weird to think about since it's all inside your body and equipment, but the deeper you are in the ocean, the more air you have in each breath. Don't quote me on the ratio here, but I think it would be something like - twice the pressure would mean twice as much gas in your lungs, it's just, at twice the pressure, it's taking up the same space as a normal breath would at normal, surface pressure. If you picture your lungs as a balloon, picture filling it down at 4x pressure. You fill the balloon to a normal looking size, then head back up to the surface. The balloon has 4 atmospheres of pressure, but the water around it will gradually become less and less of a counter. At some point, the water pressure outside the balloon isn't enough to keep the gas inside compacted, and it will pop. Essentially, your normal looking balloon at depth would become a regular balloon filled with 4 times the air at the surface.
The James Cameron video on his journey on his deep dive/journey is really interesting
I have severe thalassophobia, the fear of the ocean and deep water. This video, when I watched it, just further fueled my fear. I can't do cruises, I'd freak the fuck out. Scuba diving? Forget that. Anything that goes underwater more than ten feet, nooope. If I were to be stranded in the middle of the ocean, I'd lose my shit.
I hate it with a passion.
