What would you do with $250k?
Buy a house for sure.
Buy a house.
Its not enough to buy a house where I live. I would pay back my student loans
try to buy a house of some kind
@Elientjepientje. student loans in the England pretty much do not count towards anything so i absolutely would not 😅 im waiting for mine to get written off when I'm like 50 because by the time i earn enough, i will be paying off the interest 🤣
The titan disaster is a textbook example of what happens when an rich guy who thinks he’s always the smartest guy in the room allows his ego get ahead of physics. Physics always wins.
Yes physics don't care whether you are rich or poor,just like death it is the great levellar!
He was doing all that with other peoples money, so not exactly a rich guy. some rich people had to give him some money to play with at some point. His budget cutting is part of what weakened the vessel, he didn't have enough money to go around... "Some rich guy" lol, If I had a nickel for every time I heard that. usually thats coming from a democrat. I'm a poor boy myself but I know people who have worked their ass off to be where they're at and I'm not jealous of them. money can bring out some rotten in people, usually when they haven't worked for it. sometimes people are just smarter, no reason to hate them for that either but most rich people I know with money have worked their ass off, not really smart, some timeo
2:22 James Cameron actually made the movie such that its runtime (around three hours) IS roughly how long the ship took to sink. You can watch it exactly once!
Yeah! Also, if you do want to watch it sink, there's a real-time simulation based on everything that we know happened on youtube.
The way someone described it to me that made a lot of sense was of stepping on a can of soda. If you try to step on an unopened can of soda, you could stand on it before it would crush. However, if you open the can, now you can crush it easily and quickly. Now, instead of your foot, imagine opening the can while the weight of 3000 meters of water presses on it from every side.
3500 meters, not feet.
@@Cbd_7ohmyeah was like 12000 feet or something?
I can't not imagine the carbon fiber as shredded wheat cereal underwater.
I really needed a guy with a nose ring and cauliflower hair to explain the science behind this disaster to me.
The biggest issue with bluetooth is that the connection glitches on land. I mean, my speaker glitched twice during this podcast itself. In the deep fucking ocean, that moment can prove fatal.
I used a Logitech controller on land to play a console it was meant for and had nothing but problems. I would have noped out of the mission as soon as I saw that thing. It got me killed hundreds of times in Bioshock, it's not going to get me killed IRL.
Stockton Rush is such a fitting name for a man who's a borderline video game/comic villain. I would expect to see a name like that in Borderlands, and his behavior for that matter too lol
😂😂😂
Basically mass suicide
This whole thing is proof we live in a simulation. From his wife being related to titanic passengers to him using aerospace logic in the water, which makes no sense, to being overconfident and cocky just like the titanic captian.
I remember I went on a ferry between England and France, and heard an announcement that the ship was sinking, which repeated a couple times. Children were crying, people were panicking, the corridors were all blocked and no one could move, when another announcement started, saying, “Sorry about that, chaps, um… wrong button. The restaurant is closing in 15 minutes and… we’re not sinking.”
Anyway, it was nice to know that if it had been sinking, so many idiots would have panicked that we would all have died.
Nice episode, I guess you can say their subamarine was..... subpar. Interesting how humanity will spend millions saving some billionaires but will punish people for saving thousands:
German boat captain, Pia Klemp, faces a long and costly trial and possible 20 years of jail in Italy for her humanitarian efforts in aiding stranded migrants in the Mediterranean with the private rescue ships “Sea Watch III” and “Iuventa.”
"Sea rescue missions have been criminalized," the 35-year-old sea captain told German media outlet Basler Zeitung on June 7, adding that whether or not she ends up in jail she would challenge the ruling in the European Court of Human Rights in Strasbourg.
With her crew, Klemp rescued over 1,000 migrants that were in risk of drowning while crossing the Mediterranean Sea to reach Europe. Now she has been charged in Sicily for “assisting in illegal immigration,” as part of far-right Deputy Prime Minister Matteo Salvini’s crackdown on migration.
"Italy's fascists are using this case as a showcase to deter others from aiding migrants," international analyst and professor Rula Jebreal said on Twitter, adding that “they would prefer to let people drown in the Mediterranean."
Since assuming office, the far-right PM has sought to put a stop to migrant rescue ships docking on Italian shores and allowing refugees to disembark, under the banner of “Italy First.” On April 2019, he refused for another Sea Watch ship to dock in Italy, the vessel had saved 12 women, an 11-month-old girl and a 6-year-old boy among the group of migrants.
However, as the captain explains her actions and those of other rescue boats in the Mediterranean are completely legal and protected by the 1982 United Nations (U.N.) Law of the Sea.
According to its article 98, “every state shall require the master of a ship” to “render assistance to any person found at sea in danger of being lost” and “proceed with all possible speed to the rescue of persons in distress.”
I was hoping someone would mention this. I would add, it's estimated that over the past 10 years, more than 20,000 people have died or gone missing in the Mediterranean crossing. But since they're poor migrants and refugees, there's complete media silence. This is also why I can't bring myself to care much about the billionaires who willingly locked themselves into that rickety tube. The only person I feel bad for is the 19 year-old who got dragged along by his father.
The loss of economic migrants (who by the way pass through MANY safe nations before boarding their boats) is no detriment to the places they are being funneled into. They just show up and erode the bottom of the labour market. It's fun to watch people hate on billionaires but fawn over the tools the billionaires use to depress living and wage conditions in the west. If you have integrity, you'll deride those billionaires too. But you won't because you don't 😘
I hope Pia goes away for life and it has a chilling effect on NGOs.
Seawatch and its ilk can rot in hell along with their pets.
Thank you for mentioning migrants, they were my first thought when i saw this stuff on the news. I hate how much stuff is only relevant when rich folk are sad
A meta study has concluded: rich people dying as a result of their own hubris is objectively funny.
i would pay for top surgery and buy a house
deep down, the rich are good people
yeah, about 4000 metres deep
Nice one! Xaxax
way down, mark the grave, where the searchlights found us
I feel so bad for the 19 year old lad
😂 good joke!
Love this whole thing! You guys have a great way of explaining things in sciency ways while still keeping it all super entertaining. One quick correction though modified console controllers are actually used by the military very often for things like nuclear powered subs so it's not really a point against the maker of the sub for using one because it doesn't have much of an impact on the actual function of the sub. There were definitely many other examples though of him cutting corners and just being negligent so he's still fully to blame for what happened I just wanted to nitpick that small fact because a lot of places are trying to make that seem like a big issue when it's really nothing so hearing it come up over and over gets a little annoying you guys did great with how you discussed it though! ❤
We didn’t actually say it was issue of function, but more a case of selling $250k tickets and not bothering to spend a minuscule sum on making the controller look better
@@SciGuys Oh I definitely get that! My comment may have come off a bit wrong I wasn't really saying you guys were overplaying it as a functional issue just that it is by people in general are and the way you guys talked about it was great. The comment was more meant to just bring attention to the fact people overplay but I realize I probably could have worded it in a much better way
From what ive read, bluetooth controllers are only used for periscopes, drones, etc and other non critical navigational systems in the military, not for the actual main navigation
This is gonna be a good episode
For those who are curious and can't be bothered to Google it, Newfoundland's timezone is 1.5 hours ahead of Eastern (noon Newfoundland is 10:30am Eastern) and on summer hours it is 2.5 hours behind UTC. (Source: I live here.)
55:10 like the scene from the Expanse where the sling shot belter flung himself through The Ring in his ship and the Ring instantaneously imposed a speed limit. LOL
after watching scott manley’s video where he approximated the amount of tnt worth of energy it was, the analogy that i’ve had in my head has been that it’s like sitting inside a pile of explosives
During such a catastrophic implosion event, the human body goes from being biology to being physics.
Just FYI: yes, the bow of a boat is its front, and the stern is the back. No, I'm not a sailor of any sort; I'm a word nerd.
im australian and stone fish are one of my biggest fears too!
The controller thing isn't that weird, actually.
Lots of military vehicles use gaming controllers for control. The reason is that it reduces the training required - almost everybody knows how to use one, and the controls can easily be transferred for the vehicle.
It's admittedly a bit strange but commonplace.
That was my thought, until they said the words 'wireless' and 'bluetooth'
I would not bat an eye at a wired game controller, but bluetooth is not yet at a point that i would trust lives with it.
honestly, natural selection strikes again. im so glad you guys did an episode on this because i was trying to read up on it but all the things i found on how and out of what materials this was built felt so surreal, i thought the controller and all that was just your usual internet joke i just refused to believe that people would expect to come back alive from this adventure but apparently its all true. rest in peace silly rich people and rest in true peace, child who was scared, didnt want to go and got dragged along anyway.
How does natural selection apply here in any way? 4 out of 5 of them were comfortably out of their reproductive age and the one who actually could be accused of selecting himself out of the gene pool was 19. Are you really gonna judge someone by the dumb shit they are willing to do as a 19-year-old then most people shouldn't be allowed to live according to your standards.
A way to imagine the difference between being in the water and change in pressure/moving water could be I can stand chest high in a pool just fine and not move. Try and do it in the surf however and you either willingly move with the water (shift away and towards the shore, up with the wave) or it is taking you to shore with it (either body surfing - the recommended method, or unwillingly).
When the water went in it wasn't just being water it was coming in like a ridiculously powerful wave.
I remember when I told my 8 year old nephew about the titan he had said “if they’re rich they probably deserved to die” and that’s when I realized I need to be a LOT more careful about what I say in front of him 😬😬😬
Very entertaining one guys, really enjoyed!
I've been getting a lot of UA-cam shorts about chiropractors and I hate it so much. It got me thinking that it would be an interesting episode. I think it's one of the most normalized pseudosciences right now. Apparently the founder had a séance and then claimed a dead doctor had revealed the secrets of chiropraxis to him.
They've done a good job over the years of keeping quiet about the fact it's based on BS energy meridians and all that vague nonsense, and playing up the public misconception that it's just some kind of physical therapy.
If you want a point of comparison imagine holding a 120lb stick of dynamite and lighting the fuse. You don't feel the explosion.
What would I do with $250k? Wipe out debt, get a car, upgrade the computer, put a bunch away for my daughter, invest some...
The way I explained it to my kids was with a soda can
When the can is new, full, and there is nothing wrong with it, it’s safe. You can stop on it and it would probably be fine.
But if you start squeezing it again and again, over and over. It puts stress on the can and starts to cause damage.
Once the can is damaged you can slam your foot down on it and it will instantly crumple to nothing.
The material was not meant to take the repeated stress from going down to that depth and take that amount of pressure over and over. People went thinking “they’ve done this a bunch of times and no one got hurt. So it must be safe.” Not realizing that the more they had gone down the more dangerous it became.😢
If i had 250k i certainly wouldn't spend it going on this lego inspired sub
this is what we’ve been waiting forrrrrrrrrr
Even though it's bad they didn't have enough life boats, even if they did, it wouldn't have made a difference because they barely managed to launch the ones they did have before the ship went under, a few were also broken in the chaos.
@57:04 The only portion of the human body that is compressible in water are the parts that contain air, so the lungs, ear cannals, and the sinuses; however, if properly equalized (like divers do) these cavities are pressurized to the same level as the gas you are breathing, which at depth is the pressure of the water that surrounds you.
The problem with scuba diving to great depths like the wreck of is not the pressure in-and-of itself. The problem with diving that deep on scuba equipment are the physiological affects of breathing pressurized gasses. If you were under that much pressure in water you would not be crushed, or even really notice the weight of the water around you; however, oxygen becomes a toxic gas at about 15 feet underwater (if you were breathing pure oxygen you start to convulse at a depth of a little more than a meter), nitrogen causes nitrogen narcosis starting at around 100 feet below the surface, and at about 600 feet humans become vulnerable to high pressure nervous syndrome (HPNS) depending on the gas mix they breath.
Because of this, scuba divers going deeper than 100 feet usually breath a mixture of oxygen, nitrogen, and helium called "Trimix". A little deeper and that gas mix becomes "Heliox," which is just helium and oxygen. Finally at the greatest depths people scuba dive "Hydrox" is the breathing mix of choice, which is hydrogen and oxygen because hydrogen allows divers to go a bit deeper before HPNS sets in. Whatever the gas mix, there comes a depth where the physiological affects of breathing pressurized gas are just fatal. So it is only the affects of breathing pressurized gas and not the water pressure itself that are incompatible, at some point, with human life.
Just as an example of how it is not the "weight" or "pressure" of the water that harms a human being directly while diving, the deepest recorded scuba dive was 1,700 feet and the deepest recorded simulated dive was in a pressure tank with water pressurized to about 2,300 feet. In that pressure tank the water PSI was slightly over 1,000 pounds. The simulated dive lasted for 2 hours and the diver was not crushed to death like he would be had a single 1,000 pound weight laid on top of him on the surface. Why it works this way is complicated, but is mostly due to the principle that water does not compress itself and the human body is 70% water.
The reason Titan's implosion was so violent and reduced the human beings inside into something unrecognizable has to do with differential pressure. Basically, on the outside of the submersible you have 400 atmospheres of water pushing on the pressure vessel of the submersible that has a pocket of air at 1 atmosphere of pressure inside of it. If that pressure vessel fails, that 1 atmosphere cavity inside the pressure vessel violently equalizes with incredible speed from 1 atmosphere to the surrounding 400 atmospheres--we are talking around 3 milliseconds at Titanic's depth. This rapid equalization sends overpressure (a pressure wave) and a wall of water and debris at the occupants at supersonic speeds. In Titan's case, the energy released in this rapid equalization (implosion) was roughly equivalent to the detonation of 97kgs of TNT. Meaning that the occupants of died from the pressure wave of the implosion before they even got wet.
Edit
This is what the detonation of 100kg of TNT looks like. So imagine an implosion that releases this much energy, but instead of being directed outwardly like an explosion, it all is directed inwardly meaning anyone inside the imploding bubble is going to experience of the force acting on them.

With like just shy of £200k I’m paying off my mortgage (sensible) and then I’d still have a decent chunk left. So at that point I’m booking flights for summer and going to Australia for Christmas.
Ever since the Titanic, we know not to call anyhthing Titan, it always sinks...
Having followed a lot of nuclear, criticality and structural accident essays, there's always a common factor: pure negligence. It baffles me that none of the participants either made any research into any aspects of the trip like normal sub structures or safety protocols. Like you would plan ahead on any "vacation". They just threw money at it and expected to be taken care of like always and because other rich people told them so.
I thought it was a large portal (too large per some experts, like James Cameron) for viewing, not a screen.
The eight foot diameter titanium end caps at full depth with the water pressure at 6,000 PSI would be exerting over 43,000,000 pounds of force on the ends of the carbon fiber hull. I can't imagine the carbon fiber hull could safely manage the tremendous force from both ends and not collapse. The design was a death trap waiting to happen. Why anyone would take the risk is beyond me. I'm not so sure the hull itself failed, but was simply crushed like stepping on an empty soda can. Over 21,000 tons of pressure from both ends.
jfc the implosion description felt like an xkcd "what if" but it's very achievable actually
i haven't watched the episode yet but i'm sure as hell it's gonna be so fucking hilarious. i have a question tho. could you do an episode on age regression? IT'S COMPLETELY UNRELATED I KNOW 😭 but i've just stumbled upon it and immediately thought it would be interesting to hear you talk about it. now let me listen to you scientifically talk about rich people paying milions to die in the most bizarre way possible. love you guys keep up the good work
You compromise with "Mother Nature", not bargain. She wins everrytime!
If the pressure is so great down that deep, how does the life there survive? I know they’re likely small, but they aren’t made of metal
Water is fairly incompressible, and living things are mostly water. Deep sea creatures have some specialised proteins & other adaptations, but the main issue for us at that depth is the air in our bodies, since it heavily compresses under pressure.
@@SciGuys Aah, thank you! That makes sense to me now 🙂
almost freezing? it was 28°F that night.
The water was liquid, is more the point
little mermaid - under the sea
I feel like the pressure is sort of not important, as the pressure itself aint the problem, but rather the sudden change in pressures
I have even more respect for James Cameron.
I don't know if someone told me or if I was just a child and therefore dumb, lol, but when I was a kid I thought there were more girls than boys in the world because when the Titanic sank, the women and children were the ones ushered onto the lifeboats before the men 💀💀
That is adorable, I can totally imagine a child thinking that.
The titanic, Noah's ark, both are important boats with lots of life onboard
@SciGuys I hate to be this person but you guys misspelled implosion in the video's opening titles
I checked it multiple times but unfortunately I have ADHD and therefore cannot see any typo of my own
@@SciGuysthis is the most relatable comment I’ve seen all week tbh
If I had to spend 250k, some of that would definetly go to charity. I would maybe work fewer hours and buy rediculously expensive train tickets so that I can visit theme parks and other attractions with friends. I would probably try to invest the rest in a more risky manner, to have a chance of getting much more out of the money. No idea what I would do with the money afterwards tho... 🤷
Stockton Rushs extreme hubris unfortunately took four souls with him.
I was on the Titan 3 times. You could see out the porthole. You didn’t look at it on a screen. It was bad enough without getting basic facts wrong.
Damn, i always get rid of my patreon because of life circumstances changing and then i hear this and im like damn i need to get the patreon again to listen to after dark to hear more bashing about capitalism. I start a new job tomorrow so i will definitely be getting it next month and catch up 🤣
The Titan is actually large for a submersible.
2:35 lol 15k people 😂
If an explosion goes BOOM does an implosion go MOOB?
Well done!...whoops, correction: enod llew
ohno
Same logic as the Titanic Captin, same result
Could not. It sank in 160 minutes. The movie is over 3 hours.
Titanic movie night 🍿
Such a shame to ever cross paths with Stockton Rush if you have money. He was out there scamming the rich.
British boy, just say they got crushed like pancake.
At least the fish got a good meal out of their biological matter :P
James Cameron is the American Napoleon! (I know he's Canadian! Shut up! 🤣)
A rich child living through his imagination. I don’t need facts when my make believe says it works.
You spelled IMPLOSION wrong! IMPOLOSION????
It was a typo, I have ADHD & didn’t spot it
I've never watched any of that movie *period*.
if i had 250k i'd put a down payment on a house 🥴
1500 not 15000
No ty
No wonder you've lost The war king georgie Girl
Move to a better state. Buy a house. Take a year off.
Lies they were MURDERED
I have seen the titanic 1997 movie twice. Once on vhs in 1998 and I thought it was terrible. So boring. Could not understand why so many loved the movie. Girls fell in love with Leonardo di Caprio and his affair with the suicidal young woman. I hated it. Steuggled to get through it. Saw it a second time a week ago. Liked it a lot better and I wasn’t bored, but still not great. Like the sinking effects and screaming falling people.
So....one thought. If you guys can't spell implosion you probably are not qualified to discuss an implosion huh?
I have ADHD & made a careless typo…
@@SciGuys just kidding anyway (-:
Stop about the migrants already! If you dont want them living near you than you should not expect other people to. If you personally dont want to help, do not expect the ”gouverment” to do so, get it?
It starts with individuals!
Weird assumption that we don't want migrants living near us?
The idea that one cannot expect the government to do something unless one is willing to do it oneself is ridiculous. Apply it to any other role of the government and that becomes immediately obvious. Can I not call for better NHS funding without donating my own money to the NHS? Given that we pay taxes, calling for the government to do something is us personally wanting to help? Just via the taxes we pay to the government...
Subscription just because I really like you guys and ESPECIALLY for that mad laugh.
The Titanic only had enough lifeboats to save one third (1/3) of the people on board. "Had every lifeboat been filled accordingly, they still could have only evacuated about 53 percent of those actually on board on the night of the sinking."

👍💪🎯💪👍 First time watching.. Actually second time in a row😅😅😅 found this to be well done, respectful and ya'll homework was done on the background story.. give you four thumbs up 👍 👍 👍 👍 shame for the outcome and families left behind.. Hopefully this will be a LESSON for those who needed it 😔 🙏 😔
