A sub named the Titan was lost under the sea in June 2023 trying to reach the Titanic and contact was lost at 3,500m below sea level. The sub had a catastrophic implosion with #5 souls aboard all lost. Could you take me, in terms of milliseconds, what would have happened at the time of the implosion and compare it to the time it takes for a human to experience pain. Thank you...
I'll start by saying that this is a tragic scenario, and it's essential to respect the seriousness of a situation like sort.
Underwater implosions due to extreme pressure can happen almost instantaneously. When a submarine descends too deep, the pressure outside the vessel exceeds the submarine's hull strength, leading to an implosion. The force of the implosion would be enormous at such a depth, and the event would be over in less than a millisecond.
In terms of human perception of time, our brain takes about 150 milliseconds on average to process a visual image, and pain signals traveling via the fastest nerves can take a few milliseconds (1-2 ms) to reach the brain from the source of the pain.
Given these timeframes, it's highly likely that the individuals aboard a submarine experiencing a catastrophic implosion at a depth of 3500 meters wouldn't have time to process what was happening, let alone feel pain. The event would happen faster than our body's ability to perceive and respond to it, essentially making it instantaneous from a human perspective.
There would likely have been a rapid and significant increase in temperature in the immediate vicinity of the implosion. This increase in temperature is primarily due to adiabatic heating.
When a pressure vessel such as a submarine rapidly fails or implodes, the sudden release of pressure causes a rapid expansion of the surrounding water. This expansion occurs because the water inside the submarine is at a higher pressure than the external water at that depth.
During this rapid expansion, the water molecules experience a decrease in pressure, which leads to a decrease in density. According to the ideal gas law, when a gas expands without exchanging heat with its surroundings, its temperature increases. Although water is not a gas, this principle applies to liquids under certain conditions.
Therefore, as the water rapidly expands in the vicinity of the implosion, it will experience adiabatic heating, causing an increase in temperature. However, the magnitude and duration of this temperature increase will depend on various factors, including the size and speed of the implosion, the volume of water involved, and the initial temperature and pressure conditions.
In essence, the tragedy would be over before the brain could register any perception of pain.
