In writing every language travels at the speed of light, it’s not like it’s limited to speaking and sign language.


Solidus27 t1_itzk20c wrote

This is an incredibly confused statement. What about written text?


nave47 t1_itzlcfl wrote

My love language, pizza, tends to travel nearer the speed of traffic than the speed of sound or light.


FTMHorn t1_itzljrd wrote

What about text messages? Speed of the internet? Speed of the phone lines?

Are there even measurements for it?


Hipty t1_itzljzv wrote

There are a few other visual communication methods, although I don’t suppose they count as languages. -Semaphore (flags) -Morse Code (ship-to-ship with lights)

So if a fully functioning human stood on the moon and waved and yelled to his friend on Earth, you would see him wave and yell almost instantly, but you can only hear his shout a few seconds later. How mildly weird would that be 🤔

Well, seems like we are close to getting out of this solar system then....

  1. It would take light a bit over a second to travel from Moon to Earth, while sound would travel the same distance in 5 minutes (same distance in Earth's atmosphere)

  2. Sound actually travels rather slow, only 340 meters per second. Look up videos of people firing at steel targets at ranges over 150 meters: you would see the target move from impact, and after a split second hear the sound.

You’d never hear the sound even if they were “relatively” close to each other, like right next to each other. Sound works by vibrating molecules, primarily air since it’s everywhere. Sound also travels through solid objects which is why you can hear vibrations of objects. So it works by vibrating molecules. In space, there are no cohesive molecules. The sun is a sustained nuclear reaction and if we were able to hear it, we would be deafened by it. But we don’t hear it because there’s nothing for the sound waves to vibrate through. With space between earth and the moon, any sound that originates from one celestial body to another ceases to exist once it enters into space because there is nothing there for sound to travel to.

That nice, but when its behind your eyeballs, what's the point of speed?


S-Vagus t1_itzs87k wrote

The limitation is not on the absorption of the information as light hitting the eyes is inevitable, unpacking the information is an exercise left up to the reader because otherwise why would I have ever written these words in partciular... let alone any other.


A11ce t1_itzslev wrote

You forgot that sound needs a medium, can be a gas, liquid or solid object, but it needs one.

Also if you want to experience what you described just watch a storm one day, you see the lightning first and the sound gets to you later depending on how far away you are.


NAND_110_101_011_001 t1_itzsuts wrote

Considering "language" is an abstract concept, I don't think there is such a thing as a "speed of language". If anything, language is merely information; thus, it travels at whatever the speed of its encoding medium, up to C.


SteamKore t1_itzu2js wrote

So because of the limitations of humanity, even sign language cannot travel at the speed of light, even though we see the sign there is just the briefest of delays as synapses fire in the brain allowing for the recognition and comprehension of the language which is fast, like stupid fast, but slower than the speed of light, only because the human eye and brain slow it down.


primeprover t1_itzvlhy wrote

There will be some latency, but then they will travel at a very similar speed to the speed of light. That said the latency could be longer than the travel time. I remember reading a story once where someone had an issue sending emails further than 500 miles. Turns out there was a very fast timeout that was long enough for light to travel around 500 miles. Found it:

We should be trying to contact other planetary civilizations with sign language.


9v6XbQnR t1_itzx159 wrote

Its a fun thought!

Information density matters. How many words can each language speak per second? How many words can be accurately received per second.


RyanH090 t1_itzy909 wrote

As I read somewhere else, if you account latency speed (i.e. brain processing speed), these 2 measures will become negligible.

Muroid t1_itzzmox wrote

You can hypothetically measure the time it would take sound to travel through air a distance equivalent to the distance from the Earth to the moon even if it would not be possible for sound to actually travel from the real moon to the real Earth.


OpenGiraffe t1_iu00sq9 wrote

The light in fiber optic cables travel at the speed of light, don't they?

Only, not the characteristic speed of light in vacuum, c≈300 000 km/s. You have to take the refractive index into account. But it's still the speed of light, through that specific medium (fiber optic cable in this case).


Muroid t1_iu01r1h wrote

The speed of light almost always refers to c. It would technically be correct to refer to any speed that light travels at as “the speed of light” but given the common name of c, that is almost never what people mean or understand by the phrase “speed of light” unless it’s been very clearly specified.

The speed of light through air is very, very close to c. The speed of light through fiber optics isn’t. Still a high percentage of c so very fast, but not a value that you’d ever mistake for c. With air it’s practically a rounding error away.


gkight t1_iu08np2 wrote

I'm just saying that if you're going to say that sign language travels at the speed of light then so does text, or hyroglyphics or whatever.

Writing down the text takes time, in exactly the same way as moving your hands to the correct position in sign language. But then the transfer of the information, once formulated, is at the speed of light.

So either they both travel at the speed if light or neither does, depending how you want to think about it. Either way the OP statement is false.


YookCat t1_iu09dnh wrote

I don’t think you understand the point of hypotheticals. They’re not meant to be taken literal. It’s more of a wisdom check as opposed to an intelligence check, honestly.

It wouldn’t save time to just say the sound can’t make it, either. Even if we were doing things your way… that proceeds to leave the original premise of the hypothetical unsolved, meaning we would need to make an entirely new hypothetical to demonstrate the sound/light speed difference. If we take everything literally, it takes us more time.

Additionally, just in case you think hypotheticals are useless entirely and we should just say the facts, helping people “visualize” things is a part of the point. Examples, demonstrations, and so on are ways of teaching things, which is similar to what this hypothetical was attempting to achieve.


Memestrats4life t1_iu09x0q wrote

I see that- and do enjoy your wisdom/intelligence point- but think that dedicating time to finding exact mathematical answers to them while disregarding the most major aspect of those calculations is pointless
