  • I would agree with you that something similar to metric would eventually arise, but I would consider duodecimal to make more sense than decimal, as 12 is a superior highly composite number and the terminating representation is much shorter for more commonly used fractions (e.g. 1⁄4 would be represented as 0.3, 1⁄3 as 0.4, 1⁄2 as 0.6, etc). I would also argue that groupings in powers of 12² make more sense than 10³.

    I would also argue that it would make more sense for measurements to be based on natural units (such as Planck length) for all the basic measurements (second, metre, kilogram, ampere, kelvin, mole, and candela), such that the anthropic unit (the one you’d most commonly refer to without prefixes) would be some multiple of 12 away from the natural unit.











  • I do believe you have to have serious mental health issues to remain a billionaire, and I do pity them; in a perfect world the possibility of such wealth disparity wouldn’t exist, and those with those tendencies would get the help they need without being surrounded by yes-men hoping for a sliver of wealth. They are probably incredibly emotionally isolated and lonely, and the pain they cause through hoarding is inexcusable and it would be better for everyone if that wealth was redistributed, including themselves.





  • The sun is made of plasma, and its energy is predominantly from hydrogen fusing into helium. Plasma is what happens when atoms are so energetic that their electrons get stripped from themselves and are bouncing around in a sea of atomic nuclei and other electrons, which does a lot of things with electromagnetism. All that plasma moving around at crazy speeds and low density is what causes a sort of electromagnetic convection in addition to the normal heat-based kind, which is how you get sunspots and solar flares.

    As far as fire without carbon, any metal that can oxidize can burn, because it’s the reaction with oxygen that releases heat. The issue there is that it’s usually not self-sustaining because most of the oxidized metal stays on the surface, so there’s no more metal exposed to oxygen. You can get around this by increasing the surface area of the metal, maybe by having it in dust form (so if you had fine enough iron dust, for instance, you could burn it into rust without needing carbon, and that would very much be the image of fire). You also don’t need oxygen in molecular form (i.e. O2), it can be part of other metals (like iron oxide, rust), and that will burn with other metals so long as the chemical reaction is self-sustaining (famously, like the thermite, which is rust powder and aluminum powder mixed together at high enough temperatures). These fires aren’t “normal” but I think they count.

    As far as fire without oxygen at all, while not “normal” and I don’t think that counts under strict definitions, there are exothermic (heat-producing) reduction-oxidation reactions that are very close, like when hydrogen gas and fluorine gas combine to make hydrofluoric acid, and those might be close enough that they can look like fire in the right environment (which, again, those environments would be far from normal).
