Water pressure is borderline unimaginable at those depths. The entire atmosphere overhead, up to the edge of outer space, presses down at about 15 psi. That is, a one-square-inch of column of air extended upward contains enough air molecules to accumulate 15 pounds worth of weight. A one-square-inch column of water accumulates the same 15 pounds in only 30-35 feet. "One atmosphere per 10 meters deep." It's why our ears get uncomfortable even at fairly low depths when swimming underwater. So the 11km trench is stacking up the equivalent of 1100x the weight of the atmosphere overhead.

Maybe you want to look up "Operation Crossroads", specifically the "Baker shot" - this was the first underwater test of a nuclear weapon. Great footage.

i feel like if anything this showed me just how much energy is required to cause an earthquake or tsunami. The fact that the most destructive life ending thing we can build at the moment wouldn’t even come close to triggering such an event is pretty wild

It's great having someone like her to relax to and watch to forget about the nutcases and their crazy schemes for a time. You're appreciated 🥂

I love your videos. You are so willing to learn and so learned.

I've always appreciated Kurzgesagt videos. They're pretty clean, simple and communicate science in a simplified and pretty straightforward manner. Love this one and as always your reaction is a go! 😀.

You know, its actually understandable. Gabo’s style isn’t for everyone, he’s among my favorite authors but at the same time it’s completely understandable

A submersible is a ROV. Remote Operated Vehicle (a drone) We use them on every offshore drilling rig.

Little fun fact: if you detonate a Tsar Bomb in the Mariana Trench, you would be able to see the sea deepest floor. The light of the Tsar Bomb was seen even from 270 km from the detonation site. That means that even with 11 km of water between you and the detonation, the light would be so intense that the sea floor would became visible from the surface

I think the most interesting video from Kurzgesagt is "The egg - A short story". It's philosophical and will really get you thinking

It’s always a good day when I see a new video from you.

Hello, Jose from Puerto Rico. If I'm not mistaken, James Cameron designed that submersible he used to go down the trench. Marvelous piece of engineering, I must say. As for the video, it was quite interesting. But as George Carlin said in one of his pieces, the Tsar Bomba would just be a another mere surface nuisance our Earth just shakes away.

The bit about the earth being blown out of orbit reminded me of the old TV series "Space:1999", where the moon is knocked out of orbit and sent on a trip through space by a nuclear explosion. Find almost any conversation about that show and you'll hear why such a thing simply wouldn't happen. Chief among those arguments is the fact that any blast strong enough to actually move an object of that mass in such a short period of time would likely just shatter it. The fact is, to move the earth would require a powerful, long-duration explosion that acted like a rocket's exhaust, taking quite a while to overcome inertia. ...but in the end, also blowing the earth's atmosphere out into space long before the planet began to budge . ( That wasn't a problem for the fictional moonbase alpha, in the TV show though, since the moon doesn't have an atmosphere. ) Anyway, thoughts of screwing up earth's orbit with nukes aren't a new or recent thing.

I've never actually watched a Kurzgesagt video before but that was interesting. I'm gonna have to start clicking when the videos pop up in recommended

You need at least a million subs

I really enjoy this channel.

“I won’t get existential” 😂

The Marianas Trench is owned by nobody, nations' "territorial waters" only extend 3.5 miles from the low water line (aka baseline). It looks like it's within the "exclusive economic zone" (which extends 230 miles from the baseline) of Guam.

Same experience with 100 Years of Solitude. I felt like I was dragging myself to finish that book.

Thanks!

7:00 But this was only talking about one bomb. Image if we lined the trench with like 100 of those bombs. Or say encircled Mt. Everest with 200 Tzar Bombas, but when talking about just one in comparison to nature I would agree. I wonder what would happen if we spread out equally every nuclear bomb across the planet and detonated them simultaneously, feel like that would be more devastating than nature.

Interesting that it wouldn't change the earth's rotation. Likely because it doesn't really displace much volume. Unlike the Three Gorges Dam in China that would shift the moments of inertia enough to slow earth's rotation by 0.06 milliseconds and shift the position of the poles .08 inches. There was also an earthquake in Indonesia on 12/26/2004 that decreased the length of a day by 2.68 microseconds. Man...that's really going to jack w/Leap year in about 8.64E+10 years. Better get that on your calendar now before you forget.

2:27 neuron _activate_ *raises eyebrow and leans forward* this is me when I'm learning stuff n things heeheehee

You’re discovering all of the good channels

It's different with tectonic plates because that is solid mass against solid mass. The energy can't get absorbed as well into the land mass like it does in water.

The last underwater nuclear test was in 1962. As an old anti nuclear weapons activist, I was already aware of the concept of "tsunami bombs", and the fact that they don't work. During the Cold War, both the USSR and the US looked into this, and concluded that it wasn't feasible. While it was a thought experiment, it wasn't an idle one, and could've become much more, if they'd concluded it would work. Shallower detonations can destroy ships, though; it's hard to float on steam, the shock wave isn't very good for the hull structure, and, while less damaging to coastlines, 30 m surface waves can be more than a little inconvenient. As the video describes, the issue with "tsunami bombs" is that any gas bubble will collapse, under the pressure at such depths; we're talking about thousands of atmospheres, after all. Since the water quickly recedes back into the cavity, the displacement is countered, and doesn't propagate. Actual tsunamis are created by solid matter permanently displacing water. One might imagine using a nuclear weapon to trigger an underwater landslide, though. Unlike water, rock won't flow right back into the cavity left by the blast, but move permanently. Even then, nuclear bombs aren't really suited for blasting rock, and the water will still dampen the effect, but, even with this, there's still a fairly substantial explosion left; if the rock is already unstable... Note that there's no need to send California into the Pacific, in order to create a tsunami. A much, much smaller slide will do the trick, just fine. There's no need to worry about the Tsar Bomba, btw. It was a one off experiment; no more than one was ever produced, or ever intended to be produced. The main purpose was to scare the Hell out of Americans, by demonstrating that they no longer held superiority in nuclear bomb design, though it also yielded some scientific results. As a weapon, it was extremely difficult to use (27,000 kg is a bit unwieldy), and a massive overkill for any purpose. A bomb that would take out a city was considered practical. Taking out the suburbs was considered a bonus. Taking out the cows grazing the fields, far into the countryside, was considered excessive.

So, nuclear bombs won't destroy us, but plastic bags will.

The higher pressure underneath huge amounts of dirt is what allowed a number of underground nuclear detonations to be relatively "safe". For a while, such explosions were proposed for serious construction excavations (except for that irritating fallout that's disturbed by the later processes.)

Hello! The thing on which they descend to the maximum depth is called a bathyscaphe.

Damn I missed your intro when setting my brightness lower had to start over

Hi! A submarine is autonomous/independent, and a submersible relies on an external source of air, power, or whatever else.

I am guessing you would get some pretty pissed off fish if you did that.

I was fairly sure it's be a damp squib, so to speak, but was surprised (a little) at just how damp a squib they reckon it would potentially be. I am a bit like you with book,s i hate giving up and have only done so with a few over the many years I have been reading! I think the first book I gave up on (back some 40-odd years) was The King of Elfland's Daughter by Lord Dunsany (?sp) and the most recent (just a month or two back) was Foucault's Pendulum by Umberto Eco - I am more than happy to dilute the ire you may get by admitting I don't like some 'classics' ;)

We may be seeing that in the near future :)

I think the last underwater nuclear weapons test was the French "Amethyste" test in 1996.

It would make a huge splash. Thats about it.

Humans make an explosion. Earth says hold my beer.

It's funny, I didn't particularly like the works of Gabriel García Márquez before I read a few of them translated into my native languages of Danish and German. Before that I had only read English translations. I really loved some of his short stories and espeally "A Very Old Man with Enormous Wings" in Danish. I wish I was more proficient in Spanish, so I could read it as it was meant to be read. I had the same experience with Tolstoy. I inherited some very old Danish translations of "Anna Karinina" but it was a terrible read (and not fully translated - it just assumed you could read all the French parts). Then I read an English translation which was perhaps even worse, I cannot remember which translation it was, but then I found the translation done by Louise & Aylmer Maude which I not only found beautiful in its prose but also really helpful as it had footnotes on the pages with direct translations of nouns etc, and also an index with much more historical context of time and institutions of late 19th century Tsarist Russia.

i heard from somewhere that the preassure at the bottom of the marriana trench is like balancing the tip of the eiffle tower on every square inch of the body's surface. just some scale

you should do movie reactions

Loving your content . I just wanted to comment on a point in your video and your comment on the subject in the follow up, regarding our place in technology Vs nature, it's absolutely evident,I feel, that one huge 'advancement' in our technology over the past 60 or 70 years of using nuclear technology to power modern life is so easily destroyed by the power of nature and man's failed attempts to recognise the warning signs. Fukushima 🙏

The submarine was called Trieste

I was just thinking about the warm water, if it would be having influence on weather..

Oh, if you are interested in more about water pressure, videos about sonoluminescence and cavitation can be interesting.

Essentially, the world's largest fart bubble.

The Problem is, a Hydrogen Bomb explosion can be simply increased by Tritium and Deuterium. The Tsar Bomba had 50 Megatons but thats not the end whats possible. Theoretically you can add more and more Deuterium and Tritium until you have a Doomsday device.

While it's terrifying to think about the over 2,000 nuclear tests, they were not all "bombs". Many were done to test the use of different radioactive elements. A lot of work was needed to find the right materials for reactions, and to shield/contain them for nuclear power. Also...yeah...the militaries of the world did their thing.

One could argue that there is a rather considerable explanatory gap in the hypothetical scenario. The bomb would quite likely never make it to the bottom of the trench, as it would succumb to the underwater pressure kilometres before reaching it.

I was definitely expecting it to enhance the explosion in some catastrophic way cos that's usually how these things go lol

ALVIN was the name of the submersible!!!

the sad thing is that nuclear bombs are oversold , the Japanese cities of Hiroshima and Nagasaki were flimsily build and the wood and paper housing did burn but the concrete buildings still stood , including the Hiroshima ground zero building radioactivity has very little effect medium or long term , wildlife just love it both Japanese cities were thriving ten years later and still are , the bomb effects were less than the fact that Japan was utterly wrecked by conventional bombing and cutting off their food supply

I think the term you're looking for is bathysphere. These are spherical (thus the name), the ideal shape to withstand the greatest pressures, since the 1000 atmospheres of water doesn't have a weak point through which to force its way in.

Here's a reaction suggestion Timelapse of the future - by melodysheep kzfaq.info/get/bejne/q6pknN2mqbO5gXU.html It is 29 minutes, so probably a tad long for a reaction video. However, since I got a decent idea of your topics of interest by now, then if not as a reaction video, you'll can at least enjoy it at your own leisure. Have a nice day to all!

Notification squad!

There is a channel called 'the slow mo guys' that has a couple of videos of gunfire under water if you want a great visual of that bubble fighting with the water pressure. They film at up to half a million frames per second. Great stuff.

hey, can u please react to "The Battle of Midway 1942: Told from the Japanese Perspective"

Reminds me of that George Carlin lecture.

I couldn't finish it either.

Pretty sure

Pretty sure, the Mariana Trench (no s) is in international waters, as it is 200 miles away from the nearest islands. But of course, these islands are claimed by the US, as such, they lay claim to the trench and even declared it a national monument in 2005.

2:07 Submersibles are not submarines but submarines are submersibles. The difference between a submarine and a submersible is a submarine has enough power to leave port and come back to port under its own power. A submersible has very limited power reserves so it needs a mother ship that can launch it and recover it. In common usage by the general public, however, the word "submarine" may be used to describe a craft that is by the technical definition actually a submersible, and by the standard meaning of the word, all submarines are submersibles.

Good video but still in love with the Lady D :)

Shout out to the San Andreas Fault😂

you should have a look at melodysheep „life beyond, chapter 2“

*How Pacific Rim Started....*

I think Vsauce has a video about what would happen if everyone on earth jumped at the same time. This kinda reminded me of that.

Despite its location, the Mariana Trench is apparently a US national monument. Don't ask me how that works.

I find that what would happen if you detonated multiple nukes several miles up, essentially creating many massive EMPs and possible killing all electronics, more intriguing. Something like that anyway.

How many Nuked detonated in total - 2624, just over half by the U.S. alone

International waters are not claimed, they just are.

Have you checked out the what if history channel? I found some interesting watches on that

I wonder what would happen if you denoted the same bomb on top of the ocean? Like if the bomb was just hanging out in a sail boat. I would imagine the energy of the bomb punch into the water was cause mass tsunamis since the pressure is not going to fight back. Also having everything on the surface level would likely make the rains that are carried to the Philippines much worse.

I remember one time I was reading Guns, Germs, and Steel by Jared Diamond. I don't remember how far I got through it before I gave up and switched to an audiobook. My ADHD gets the better of me at times. Do you ever resort to that, or do you prefer reading?

Vonnegut, "Mother Night" please read it...

Ok, so the trench won't work. How about a bomb in Yellowstone to trigger a super volcano?

Why have you lived in so many places? Military parents? You should do a Q&A :(

Analytics ✌️😎

"The Earth is fine, the people are f*****". - George Carlin

Our tech is barely comparable to what the largest volcanos can do.

Where’s the link to the original video?

Peace and love no more wars 😢❤ sent the evil doers to another planet or to he'll they can fight against each other there it's horrible to know we can all die in an instant it's so stupid let people live a life without fear love and hugs Larry Joe 😊

when you say submersible are you meaning bathosphere?

Try shooting a bullet through water

"Shout out to the San Andreas fault" 🤣🤣😂🤔🤣

Fukushima

„Kurz gesagt“ is German and means in short/ said shortly 😊

Ve seen the future it was desolate but dreams are opposite to reality believe in life the ability to create and destroy is in our DNA

I wish they would have covered nukes made for earthquakes and tsunamis. I suppose now I know why they need to be made different, but I'd love to learn more. PS you can't be sure when a nuke was blown up underwater. The timing of Japan is suspicious, they were making Russia, which claims to have tsunami bombs, very unhappy, when their "natural disaster" happened.

The trench falls under maritime law.

you can not detonate a bomb in the trench as it is 7 miles to the bottom it will crush like a Pepsi can

Sponge bob bikini bottom nuclear theory was made because of the Pikinni atoll nuclear bomb test launching place in the pacific ocean

We have detonated nuclear bombs in the ocean 20 nuclear bombs were detonated in bikini atoll in early days

I'd strongly recommend not trying it. But Humans, ya know......

Pistol shrimps do that every day!

Its about time that we got over the fact that the titanic is not really that deap. Neither is the ocean.

Something rarely talked about are the early nuclear weapons tests. We talk about the tests afterward but don't spend enough time talking about just how stupid scientists and governments can be during things like arms races. It is absolutely a fact that Oppenheimer et al. believed there was a real possibility that the first bomb, exploded at the Trinity site near White Sands missile range in New Mexico, might have ignited the atmosphere and killed the world. We aren't talking about some non-zero fractional probability, either. A Real Chance they might be ending the world, and they did it anyway, figuring that if not them, the Russians would do it. If anybody is going to end the world, it will be the USA, damn it! It is fascinating that they never even considered proposing an international ban on weaponizing nuclear technology. They thought the chance they were about to end the world was significant, and they did it anyway. Humans are stupid no matter how smart we think we are.

Well, that was anti-climactic. LoL

OCEAN 1 BOMB 0

YES! The marquis de sard. NOT BIG AND NOT CLEVER. Just a dirty man (120 days of sodam of course)

3 titanics? You Brits will use anything to measure. Stones, hands, ships...
