Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Holy shit and all of that happens within 2 nanoseconds I think? So that's why the victims in that submarine wouldn't even know it already happened because our brain takes 4 nanoseconds before we could process that pain.

The velocity of a catastrophic implosion like that would exceed Mach 2 (686 m/s). Nerve conduction is about 50-60 m/s. Dead before they knew anything was going wrong.

More in the range of a couple of milliseconds. The fragments of sub wall have to accelerate from zero over a distance of maybe 30cm before they hit a person (obviously depending on where the person is inside the sub).

Too fast to register mentally or even catch on standard video equipment in either case.

There's a big chance they've all passed out from lack of oxygen by the time this happened. It's instant death either way.
