Both meters and seconds are units of Earth specific measures of space and time. Pretty sure at a cosmic scale god would give fuckall about how we measure and name our shit

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.
For a second i thought you were calling the metric system masturbatory and then i remembered that christians really do think god watches them jork it. Kinky
There's a Family Guy episode referencing that.
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.
SI being capable of interspecies translation is an interesting thing I hadn't considered.

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.
Every base is base 10 dumdum
0, 1, 2, 10, 11, 12, 20, 21...
e: starting at 0 to not shame programmers.
That's true. It should really be referenced by the number before 10 (e.g. Base 9 for 0-1-2-3-4-5-6-7-8-9-10).
Woah, I had never considered that. To think, all these years I was on the side of "initial index is 1." I've unknowingly been using "initial index is 0," since I started using numbers.
oh-my-god-i-get-it-now.jpeg
IMO it should be called "base 9+1". It is a "base 10" system because each order of magnitude is 10x as big as the previous one. But, the key thing is to know which digit is the last one before you roll over.

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.
Base 10 is also cultural. Babylon used 60, ancient Egypt had 12 (they counted on the bones in their fingers), Rome had 5, and my wife just spent 10 minutes arguing for 8

Also "in a vacuum" would be assumed, since almost the entire universe is a vacuum.
i've just figured out how the religious universe ends. some physicist explains to their god that a lot of their assumptions were based on something being in a vacuum, and then their god says "what vacuum? you mean all that sparse hydrogen?" so the physicist says "let's find out what happens when you have a real vacuum" and then the universe ends at the speed of dumbassery.

1 Dumbass = 299 792 458 m/s
Thanks, God. We'll spend the next 3000 years obsessing over that.
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.

The actual answer is
-
because the universe had to pick a finite number and it probably doesnt use meters as an internal measurement ruler for scaling so it's an arbitrary large random number to us.
-
Why did it have to pick a finite number? Because it has finite lifespan and resources for actualization. This forces hard speed limit.
-
The speed of light has nothing to do with light it's a shitty name that makes understanding its true nature needlessly complex.
In actuality all massless waves/particles including photons, gravitational waves, and neutrinos will move at the speed of light, because thats as fast as anything massless can go. Its a universal speed limit for any real mass-particle, which is ultimately governed by Planck's constant and the symmetry preservation of Penrose spacetime diagrams. Its the speed of causality a universal framerate limit that tells us the universe flows/computes through discrete microstates with ultimate precision limit bounds.
Nice description. I enjoyed your argument. Just a small correction from my side, neutrinos aren't massless. They are very, very low mass though, and so naturally move very close to c.
You seem smart.
Can I ask you a question about the speed of light? We measured it as whatever we measured it recently. As in not 13-14 billion years ago. We also noticed that the expansion on the universe is getting faster.
Is it possible that the speed of light changed since the big bang? We just assume it's the same but what if light (photons or whatever) started off slower and gradually speed up and got more efficient. Kinda like speed runners in video games. We wouldn't have noticed the changed because we measured it after it got faster. And now with the universe expanding faster, maybe light is getting even more quick.
I heard the idea on a YT video and I've been thinking about it.
What your asking directly stems from two related open ended philosophy-of-science questions. These would be " Are universal constants actually constant?" and "Does the speed of light differ in speed at any point of time in its journey between two points of space in a continuous substrate?"
The answer to both like all philosophy questions is a long hit on the pot pipe and a "sure man, its possible but remains unlikely/over engineering the problem until we have justification through observing it" however I'll give my two cents.
"" Are universal constants actually constant?" " it probably depends on the constant. Fundamental math stuff that tie directly into computations logic and uncertainty precision limits like pi are eternal and unchanging. More physics type constants derived from statistical distribution like the cosmological constant might shift around a little especially at quantum precision error scales.
The speed of light probably is closer to the first one as its ultimately about mathematically derived logical boundaries on how fast any two points universe can interact to quantize a microstate. Its a computational limit and I don't see that changing unless the actual vaccum substrate of spacetime takes a sudden phase shift.
"Does the speed of light differ in speed at any point of time in its journey between two points of space in a continuous substrate?"
Veritasium did a good video about this one. The answer is its possible but currently unmeasurable . so if all hypothesis generate the same effective results then the simplest among them (light maintaining a constant speed during both ways of trip) is the most simple computationally efficient hypothesis among them.

It doesn’t make sense to me to read it as a single unit of dumbass. I think it’s supposed to say “1, dumbass”. God admonishing the person.
Can somebody reupload the image at a non-feddit.org host? Feddit is incredibly annoying in that it geoblocks most of Asia.
--
Wait what? Why?
Well apparently asia is the source of a lot of scraping traffic, and they're an European focused website, so they went with the nuclear option of blocking the entire continent and change. Never mind that as one of the bigger instances on the Threadiverse, they're degrading the user experience for an entire continent. I brought the issue up to them previously, but they didn't seem too concerned about it.
Example of degraded user experience for Asia:
Sorry, your reply is still hosted on the feddit.org instance, it's still unavailable to me :(
Man: why is the speed of light that?
God: what
Man: the speed of light in a vacuum is 299,792,458 meters per second... why?
God: first of all, the speed of light is 1 dumbass
Speed of light in a true vacuum.
Speed of light through any non-vacuum decreases.
The speed of causality remains the same.

Because the CPU runs at 300GHz.
Physicists all around would start crying, that’s for sure
