Yes, the Planck length

And as we know, dumbasses are quick.

MFW I get a ticket for going 5.374x10^-8^ dumbasses in a 4.633x10^-8^ dumbasses zone

that is the linear rate at which dumbassery expands, yes. also light, but that's because as yet tachyons remain hypothetical/fictional and i figure dumbassyons would travel faster than light were it possible.

like how sometimes you can look at someone or something and think "some dumbass is going to do some dumbass shit here soon" even though the dumbassery has not yet begun.

If a god existed and gave a so much of a shit about our masturbatory habits he’d be at least tangentially aware of what the fuck a meter was.

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.

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.

I understand nothing I've just read but I'm glad you science folk have fun and funding.

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.

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. "honey could you pelase move the couch 6,25 × 1034 planck lengths to the left? [1m])
