Let's first state our assumptions:

  • Very thin membrane, the balloon skin cannot be compressed more than it already is

  • Zero trapped air

  • Isothermal conditions, water temperature at the bottom of the ocean is the same as the top, that way we don't need to deal with thermal expansion

  • Balloon is a perfect sphere

Calculations:

  1. Pressure on the balloon is densitygravitydepth ~= 1000 x 10 x 100 = 1 Mpa or 10 atmospheres

  2. The bulk modulus of water is 2.2 Gpa so (change in volume)/(initial volume) = (change in pressure)/(bulk modulus) = 0.0046% decrease in volume

0.0046% decrease in volume is like a 0.015% decrease in radius

So yes the balloon does get a little bit smaller

    The "resources" we rely on require (working) humans, less working humans means less resources. The population we have today won't disappear all at once but when they age out of the workforce, a smaller population will not be able to support them

    In other words, if we are below replacement level, we will eventually have a situation where the old outnumber the young, which means that the young have to work harder to support the old

    Work in security/as a security guard

    The baseline pay is decent, and if you want you can get certifications that up you're wage by a bit

    OT is plentiful and the job is a joke TBH all I did was walk around and wave to people for the most part
