  • The earth’s core is about 5500C and is mostly composed of iron and nickel, probably. Presumably, it would shrink tremendously going from 5500C to 0C so in theory you could calculate the rate of shrinkage using iron’s rate of thermal expansion. However the core is also under immense pressure which makes iron much denser (smaller) than on the surface of the earth. The immense temperature and pressure is a result of the action of gravity pulling the core onto itself.

    The short answer I think is the earth cannot exist as we know it at anything below its core temp of 5500. Suppose we waved a magical wand that set it’s temperature to 0, it would implode on itself (along with the rest of the planet) and heat right back up to its current core temp of 5500 before you could measure the effects of thermal expansion.





  • You crave salt and fat because your body needs a little bit of these things to survive, but finding salt and fat out in nature is really really hard, so those cavemen that liked the taste of salty or fatty foods enough to make the extra effort to find those foods were more likely to survive to be your ancestors and you inherited that behaviour. That’s why you like McDonald’s, it’s full of the salt and fat that is hard to obtain if your diet consists of mostly roots and mushrooms and leaves.

    McDonalds is bad for you because it’s unnaturally full of salt and fat. Far, far more than your body needs and far more than your cavemen ancestors would have eaten naturally. Especially if you eat McDonald’s often. Too much of anything turns that thing into a poison.

    McDonald’s has only been around a generation or two. That’s not enough time for the people who crave McDonalds and eat too much of it to die off, leaving mostly people who don’t crave McDonalds to remain.




  • “Selfish” would be a situation where sufficient community exists that cooperation is at all possible. I think most preppers will simply tell you that they are expecting and prepping for complete collapse. As in, like it or not, “every man for themselves” would come to them, not them seeking it out.

    In other words, without arguing why a “every man for themselves” situation can’t or will never happen, the rest of your argument becomes irrelevant.

    Now that question is fascinating. Haiti comes to mind as an example scenario. Are community-skills relevant in the face of roaming gangs and anarchy? I think that depends on how desperate these gangs are for immediate versus long term survival and planning. I’m also not sure Haiti is an exhaustive example of the types of societal collapse that are possible or likely.


  • The amortization length affects proportion of principle paid down, but it doesn’t eliminate it entirely. At the same interest rate, you end up having paid more in interest at maturity of a longer amortization, yes. In practice, this can be mostly mitigated by negotiating a lower rate, or negotiating and exercising prepayment privileges.

    More importantly, with a mortgage, ownership of the property is yours entirely, from day one, not the lenders’. What you owe is cash, not the property. The property is merely collateral in the event of default of payment.

    BTW, multi generational loan agreements are not new. They are somewhat common historically and in other places of the world. For the same reason that multigenerational housing is the historical norm.


  • Yes and no. A lot of people are misinformed. It’s easy to say not being misinformed is the responsibility of the individual, just like recycling plastic is the responsibility of the individual consumer. Reality is a bit more nuanced. Misinformed people often simply don’t have access to good information or critical thinking skills to not be duped. Many others are straight up vulnerable to manipulation, through fears etc.

    Democracy only works if people are informed. I think the American system has failed catastrophically to inform ordinary people.


  • Governments are the product of the people. There is no divine or natural laws that triggers “an election”. A government is simply created from thin air when a group of people (any group of people) get together and say: fuck the old system, we are putting that in the trash and signing a new social contract.

    Of course, there’s virtually never unanimity of agreement over this social contract in one geographic area, so that social contract is only as binding as the force used to put it in effect.

    Realistically, 6 months+ of government shutdown in the US will likely cause a collapse of the USA as a single unified federal entity, since the federal government effectively rots. At that point, all bets are off. A fracture of the US is very possible.
