  2. There is 14.5lbs of pressure pressing against every inch of your body but you don't feel it because it has always been there, humans (and all sea-level dwelling creatures) have evolved to effortlessly endure this, it is the pressure from the atmosphere (air) pushing down on you and is known as "1 atmosphere" of pressure. In space 200 miles above our head there is no atmosphere, just vacuum, so no pressure aka zero atmosphere. But although the difference between zero and 1 is 200 to 300 miles upward, the difference between 1 and 2 is just 33 feet (a tiny bit over 10 metres) downward. This is because we move from air in to water and water is so many magnitudes denser than air, it is seriously heavy. Also for every 10 metres after that pressure again increases by 1 atmosphere. Humans can safely dive to about 60 metres, or 6 atmospheres, before the pressure becomes detrimental and exhausting to move around in. A typical submarine can safely operate around 400 metres (40 atmospheres) and even then the pressure is like having the entire weight of a car pushing on every single inch of the submarine's surface, any weak spot could cause a submarine to implode like someone standing on a balloon. The Atlantic ocean is typically about 3 and a half kilometres deep, that's 3,500 metres, at that depth anything containing air, even a thick sold steel barrel, would be crushed like a beer can. This is why the stern of Titanic was utterly wrecked while the bow wasn't - the bow filled up with water over two hours as Titanic was slowly sinking, when the bow broke off and fell to the ocean floor it was full of water and so it wasn't crushed, but the stern which was raised up out of the water was empty of water, so when the bow snapped off and the stern started to fill with water it fell faster than it could fill up and all of the pockets of air - cabins, corridors, tanks, containers, air pockets between compartments - all crumpled and imploded sending bits of the stern flying as they burst inwards under the pressure. This is why the stern has little or no plating still on it and why it has a massive debris field around it. I know this post is a bit more info than you asked for, but no, no one would be alive by the time the stern reached the bottom, anyone still inside it (and there were hundreds unable to get up on deck) would have died in the first minute as it plummeted beyond 300 metres, all of the spaces people were in would have smashed in on them killing them instantly. As scary as it would have been it still would have been a much faster death than the hundreds who spent 5 to 15 minutes freezing to death up on the surface.

  3. That is true, the ship was the first to have multiple watertight compartments, so even ramming the iceberg at full speed would have just annihilated the front of the ship but only damaged 2 or 3 compartments. Enough to stay afloat. But when you only have a few seconds to make a decision and you believe you can avoid an iceberg completely you decide to turn and that is why the Titanic was ripped along it's side. It is debated whether if Captain Smith with his experience had been awake he would have realised the iceberg was unavoidable and simply reversed the engines allowing Titanic to drift slowly in to the iceberg. A lot of people blame the fact an inexperienced officer was in charge.

  5. James Cameron is an amateur oceanographer (if there is such a thing), he's one of only four or five people to have visited the Mariana trench (deepest area on Earth) and he did so in his own submarine design. He was also part of the team that found Titanic in the late 80's and his dream was to make a movie about it.

  6. 1 atmosphere of pressure every 10 metres, they would have died within the first minute of the stern going under, any pocket of air would have been crushed like a beer can by 200 or 300 metres down. More humane than freezing to death on the surface, although a lot scarier arguably.

  7. MaiCohWolf, it's basic displacement, it's also why people tell you to get as far away as you can from a ship that is moments away from sinking. There is a suction effect when something drops below the surface of a fluid, the surrounding water (and any lifeboats or people) in it will be dragged in to fill the gap that is left behind and everything will get dragged under. This force actually keeps going straight to the bottom, as a 100,000 tonne ship falls through the water it will drag anything nearby in to the void behind it and when that ship finally comes to a halt on the ocean floor the enormous pressure of the water following it will hit like an enormous sledgehammer. That is known as downblast. Anything moving through a fluid, be it a ship through water or a hand through air, will drag that fluid with it to fill the gap left behind. The best way to observe this force is with a fluid that is very viscous like syrup or honey, if you push a spoon in to something like syrup you will see the syrup try to fill the hole left by the spoon, now in water the force is much faster, and with something the size of a passenger liner the force is a trillion times stronger. This is why the lifeboats were ordered to withdraw and then come back later, to avoid being pulled under with the ship, they waited to long however before returning and everyone froze.

  8. They had no way of knowing that the iceberg would kill them, they simply tried to avoid hitting the propellers because a ship with damaged propulsion is dead in the water. Even in what they probably thought was the worst case scenario (the ship would sink, but it would take days) they would at least have propulsion to get to a dock in time.

  9. The left side of the ship had a long corridor that ran above the bulkheads, once the bow sank low enough this passageway acted like an artery that allowed water to travel further in to different compartments, so even though the water was coming in on the right it was being shared out on the left.

  10. Because deactivating that floor wouldn't cross the mind of the person reprogramming the elevator? If you make assumptions often you should keep them to yourself, assuming is a weakness and when society falls making assumptions will get you killed, raped, eaten or a combination of the three :)

  11. Not only assumptive but stupid, it's not people in the elevator that mind it's those outside who have 10+ floors to travel but can't get in because those who got in ahead of them want to travel up a single flight or two. Think outside the box, in this case quite literally.

  12. They were not attached to the ship, they just sat on the ship and were held in place by gravity and guy wires. As soon as the ship was at too much of an angle they fell over like glasses on a table being tipped up.

  16. Actually Chris, it would not have sunk. The watertight doors did not go all the way up, but they did not have to because if only the specified number of compartments had flooded then the bow, or stern, or wherever was hit would have stayed high enough in the water. It was the weight of the water that pulled the bow low enough for water to pass over the compartments, something the designers knew about but believed could only happen if a captain was stupid enough to tear a 100m long hole in his ship negating the use of the compartments. Had they even rammed the iceberg at the ship's top speed it would have written off the ship and annihilated up to 3 compartments but the weight of 3 filled compartments would not be enough to pull the bow low enough for water to ride over in to compartment 4 and beyond, they would have been able to limp home with 30,000 tonnes of seawater onboard. It is debated that had Captain Smith been at the helm instead of in bed then his experience might have led him to know the iceberg was unavoidable and simply to reverse engines and let the ship coast in to the iceberg, wrecking the bow.

  17. Odd question to ask because anyone who has drowned is likely dead. Although those who have survived have said it's a horrible feeling, like holding your breath too long but in the moments after you give in to the water and it fills your lungs the panic subsides a little. But you die. Or get rescued.

  18. Only the first 3 vented smoke, but all 4 could vent steam and as the boiler rooms flooded there was lots of that.

  19.  @matt_canon  The Californian could have steamed at a quarter of it's speed and still reached Titanic so being in an ice field was no excuse. They were asleep.
