    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.


  • In a more general way, other creatures don’t experience taste the same way we do.

    Bird poop is really nutritious to seeds. It makes sense for those plants to be eaten by birds (with the seed passing through the digestive tract untouched), but avoid other creatures.

    Enter capcasin. Mammals find it intolerable (except for one subset of a goofy bipedal species), but birds love that shit.
