minus-squareVictor@lemmy.worldlinkfedilinkarrow-up0·2 months agoThe problem is that the meter is originally defined in terms of the size of the earth, which is in no way related to the speed of light.
minus-squareRandomVideos@programming.devlinkfedilinkarrow-up0·2 months agoWasnt it defined using a wrong measurement of the size of the Earth?
minus-squareVictor@lemmy.worldlinkfedilinkarrow-up0·edit-22 months agoWell yes, but only by a little. It was using ancient measuring techniques which were highly error-prone. Like running from one place to the next and counting the length manually. Shit like that. Still impressively close to the real size!
minus-squareRandomVideos@programming.devlinkfedilinkarrow-up0·2 months agoBut if the people deciding what the meter was at first were allowed to make errors, why werent the people deciding what the new meter was?
minus-squareVictor@lemmy.worldlinkfedilinkarrow-up0·edit-21 month agoLike what the other person said, you don’t know the extent of your error until you have a more accurate measuring technique. And you don’t just redefine an already-established unit. 😅 Rather, all the things that depend on the meter will be fucked up instead.
