  • Rate of Death in an uninhabitable pressure system = Δpsi / Δtime

    Pressure within a Human Body ≈ 14.5 psi

    Pressure in a (true) vacuum = 0 psi

    Pressure on the floor of Mariano Trench ≈ 15,750 psi

    Thus:

    Answer to "where do you die more quickly" = Mariana Trench

    Newtonian classical physics anyone...anyone?

  • my 600 million would go towards hopefully exploring Europa. It wouldn't pay for the whole thing, but it's a start.

  • We all know that a cinema screening Breaking dawn part 2 is where any sane person would die fastest.The most inhospitable place on the planet.

  • Your body WILL explode in space, because the ludicrously low temperatures would cause the water in your body (all 70ish percent of the body) to freeze and expand with increacible speed, causing you to burst.

  • What will happen if you suddenly appeared at the Moon?

  • Is there a wacuum INSIDE the space suits?

  • I would invest them on making a friendly singularity (technological) :D

  • Human pancake! Yummy!

  • Actually, only if your blood is exposed to the vacuum will it boil. As long as it's in your body, there is pressure on it... your body will not explode in a vacuum. If that were the case, space suits wouldn't work.

  • However, they would not remain intact permanently, as calcium dissolves at those pressures.

  • Steel of the Sub would certainly crush you much more completely than just being exposed to that pressure at depth - still faster than being exposed to a vacuum. Main point, if you suddenly appeared at that depth, your lungs would be crushed instantly, the force would crush your ribs in and destroy your heart and internal organs in that region very quickly because pressures at that depth are ~ 16,000 psi. Your sinus cavities and ears would implode as well, but your bones would still be intact.
