      It’s neat to think about what units an alien civilization would come up with independently. Like the Plank Distance is fundamental to physics, so they’d probably have something for that.

      Degrees Celsius is based on freezing and boiling point of water, so if they came up with a base 10 numbering system and water is key to their biology, then they’d probably come up with that.

      A calorie is the energy needed to increase the temperature of 1L of water by 1C. A liter is a volume of a cube 0.1m on each side. The meter was originally ten-millionth of the distance between the equator and north pole (and subsequent redefinitions are based on that original measurement). They wouldn’t come up with the meter, and they wouldn’t come up with liters or calories, either.

        Water’s boiling point and freezing point depends on the pressure of the local atmosphere unfortunately! But I like your logic.

        Hopefully they’d come up with a better numbering system than base 10. Base 10 is the worst part of metric tbh.

        Waters boiling point isn’t a constant though… it’s dependent on the atmosphere.

        Hell there’s also no telling if our preference to base 10 is relative to our number of fingers so neither of those are givens.

      Actually most constants have been standardized to natural sources. A meter is now a fixed (small) fraction of the speed of light in vacuum. A second is pegged to the duration of a Cesium isotope spinning or something. Just that the multipliers are chosen to be convenient to us.

      Should we need to talk measurements with aliens, we can, and can convert between their units and ours.

        Well, akshually they started out as being earth specific, as convenient ways to measure human-relevant amounts of space and time, and were standardized after that. So really God still wouldn’t care to use meters or seconds, but would probably have their own units which could also be standardized with natural phenomena.

        Right but the actual quantities are arbitrary. A metre is a fixed fraction of the speed of light in a vacuum, but it’s an arbitrary fraction chosen because it was convenient. We could just as well have chosen it to be half or twice as long. Same with the second. And the kilogram, etc.

    There are various systems of units where select physical constants are set to 1. A handy comparison chart is on Wikipedia: en.wikipedia.org/wiki/Natural_units?wprov=sfla1

    It turns out you can’t harmonize all the physical constants. Some will necessarily end up as some non-round number.

    Most of them have speed of light = 1, but some have it as 1/α where α is the fine-structure constant (α = e² / 4πε₀ħc ≈ 0.007297)

      IMO it might be better to only look at natural units that don’t depend on the specific properties of matter (i.e. proton mass, electron charge, …)

      arguably, there could be an alien civilization in our universe that is purely made of exotic matter somewhere really far away, we simply haven’t found it yet. It’s purely made of exons and kaions and yppsons and particles that don’t exist on earth, where an exon has a positive charge of 1.456… proton charges and an yppson has a negative charge of -4.132… proton charges and so on.

      therefore i consider physical constants such as ħ and c and G more fundamental than e and such, because those numbers would be the same even for exotic matter, i claim.

      then, is that reduced set of natural constants harmonizable?

      Not arbitrary.

      Since 2019, the meter has been defined as the length of the path traveled by light in vacuum during a time interval of ⁠1/299792458⁠ of a second, where the second is defined by a hyper-fine transition frequency of caesium.

        I mean, that is pretty arbitrary. The reason the divisor is that specific constant is because we already had meters before we knew the speed of light.

        You are correctly trying to say it’s well defined, but you are complaining about the wrong comment. You should check the meaning of “arbitrary” again.

        Anyway, it’s not entirely arbitrary because it was created to represent a “round” fraction of the Earth’s circumference that is similar to the length of a person’s arms. But it deviated from that too, so it’s subjective how much that counts.

      c is pretty round (universal symbol for the speed of light)

      aside from that, nothing. as science and maths are mere attempts at describing the universe all our units are arbitrary, decided to be the way they are purely because you just need to pick something to be your reference point.

      at no point has a true non-artificial unit emerged, there is no constant size of anything that could aid in that (one contestant for that title could be the planck lenght but that’ss just incredibly inconvenient to use.

        I like the idea of basing everything off fractions of the speed of light, but still keeping base ten. Define 1 year as the time it takes for Earth to go around the sun(somewhat arbitrary in that its human centric, but the alternative seems to be defining it based off an arbitrary phenomena or an arbitrary factor of the planc length). Define 1 month as one tenth of that, and so forth. Admittedly our days wont line up with the day night cycle, but who needs that? Days are arbitrary anyways, and only matter to ensure your factory workers show up as soon as theyre legally allowed to.

        That is the least arbitrary unit system. It’s the only unit that actually matters. Meters are arbitrary, in that it’s a number chosen to be useful to humans. The speed of light isn’t. It’s a measurement of a natural phenomenon, which we didn’t decide. (arguably, the time measurement is arbitrary though.)

      The meter isn’t really arbitrary, even when you ignore the description by @jumperalex. It was originally defined as 1/10,000,000th the distance from Earth’s pole to the equator, which is a pretty reasonable basis to use by 1791 standards.

        That’s still arbitrary. The definition is just something that gave a result that was a useful scale for humans. There’s no reason to pick that over, say, the average distance to the moon, or something else. That distance is just fairly easy to measure and reasonably consistent over time. There are other choices for it though. The 1/10,000,000 is just whatever number was needed to make it useful. Nature doesn’t care about that distance, unlike the speed of light.
