>Speed of light is 299 792 458 m / s>If 1 meter was redefined as 0.999308193 m it would lead to light being perfectly 300,000,000 m/s>shorter by about 0.069% (≈ 0.692 mm).The creation of a meter is a great idea, and it's a unit that is on the scale that humans can work with. however, we got painfully close to getting it to be a perfect clean fraction of the speed of light, and we didn't know at the time it's the perfect thing to base measurements off of since it's a universal constant. The difference between this "light speed meter" and the real meter is imperceptible to the average person, but would result in a nice clean number for the speed of light. No one knows the speed of light off hand. This way everyone would.
Or you could change the definition of a second.Would probably be even less noticeable.
>>17002946We just use 3E8 for c in any calculation anyways but you probably dropped out in 5th grade
>>17002946Hexadecimal ststem and we are talking
>>17002946it is a clean number, it's the exact GPS coordinates of the Giza pyramid. which also for some reason has sides that are perfectly parallel with lat/long lines
>>17003078Maybe for you, I'd notice immediately
>>17002946And here America wins again.You want to know how fast light travels?1 foot per nanosecond.No annoying eurogay nonce confusion about a regulatory commission to find how much they are allowed to spend on determining funding limits for identifying the next decimal.
>>17002946They already redefined the meter once so that the speed of light would be 299 792 458 m / s. It was hard for the Scientific community to convince the European governments to redefine the meter already and you want them to do it again now? Lol.
>>17002946Not going to happen. There's no real value in making sure speed of light is a round number, it's not a relevant number to most things, in comparison meter is everywhere and changing it would have massive ramifications. The inertia is just far too large for a change as massive as this.This isn't even like the metric vs imperial thing where the "better" system has at the very least clear and concrete improvement on the other end. Metric system is massively better than imperial and yet it just isn't worth the hassle to change everything just to adopt it. Making sure speed of light is a round number benefits essentially no one except like I dunno 7th graders when they have to remember what the speed of light is on a test or something.
>>17003187Yes, the cat is out of the bag and it's too late to change it. But, I'm saying that if you are going to base your unit of measurement on something, it should be a univeral constant and nothing is better than the speed of light in a vacuum. Initially it was longitudal coordinates, which is not tied to any geography per se, and thus culturally universal for Terrans (people from earth). However, the size and shape of earth is not a universal constant, and if you explained what a meter is given the original definitions an alien would not understand it. So start with the speed of light, then work backwards from THAT. The meter was made right at the start of modern science, about a century before they got to the speed of light and confirmed it was a constant. If the metric system was made a century later, for sure they would have used the speed of light. >>17003174The new definition of a meter is based on the speed of light anyways, but the actual length was not changed. It's just painfully CLOSE to a perfect fraction of the speed of light. Painfully so.
>>17003339did they confirm it was a constant? I remember hearing something about only know how fast it is on average going in both directions. They could be pretty far off.
>>17003346It's a constant in a vacuum regardless of frame of reference, and its the backbone of relativity.
>>17003339The other counter would be that a second is itself, entirely earth dependent. So how do you come up with a universal time unit? Plank's time and length MAY be a universal constant, but we're not completely sure. So if you show plank's time to someone from another galaxy, they know what you're talking about. But would not know what the hell a second is, without an explanation of the size and rotation of our home planet.
>>17003339>and if you explained what a meter is given the original definitions an alien would not understand it.Aliens would understand that our meter is 1/299792458 of the distance speed of light travels in a second just as easily as if it was 1/300000000 there's no fundamental difference between the two. Aliens will also almost certain have schizophrenic units simply because they will inevitably come up with their units the exact way we did, measure some kings leg or shlong and conclude that this is how the universe should be measured. Our second is also equally arbitrary, it's "based" on something but what it's "based" on is arbitrary and merely selected to most closely resemble our more original hand wavy second.
