This is the topic I've been studying on and off for several years, very interesting one. Apart from playing with the factors and primes, dividends and denominators, I'd like to exert from the basics.

Speed of light is regarded as a universal physical constant which can be reflected to some distance per some cycle of time, for example metre(s) per second(s). So we are forced to define units in use, and argue, why the selected ones are special over the others.

What is the metre:


Originally relative to the length of the meridian (explains correlations of some calculations with 40000), nowadays relative to the speed of light in vacuum.

This looks like a reference to the circular definition. But what is a second:


Originally a subdivision of the moon cycle, then mean solar time, then for a short period of time ephemeris time (that is an interesting idea really, which brings you to both philosophical understanding of time, as well as possibly groundbreaking scientific definition of time, see Julian Barbour and his theory of Shape Dynamics), finally based on atomic time. Second is:

"the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom"

We can also calculate that because light travels one meter in 1 / 299 792 458 seconds (~3.3356 nanoseconds), it takes ~30.67 times for the Cesium atom to transit when light has moved one meter. Or light has moved 3,26 cm when the Cesium atom has made one transit. Just to ponder ideas of the relativeness of the concepts of time and distance, speed.

Rather than asking, if ancients knew the speed of light, I'd ask, if they had a sense for this kind of relativeness? They were observing sky, measuring earth, doing expeditions to seas, building temples based on human and relative stellar proportions. Did they knew, that distance is relative to time cycles, that by counting cycles one defines distances? That is pretty crusial because all kinds of measurement units could be reduced to cycles.

It is probably too bold to think that they also realized that faster you travel away, shorter the measuring rod in the hands of Serapis would be! But heck'a'way, why not calculate, how fast would you need to travel to the host of Nut to get Royal Cubit stretched back to the Mundane one?!



If you only knew the magnificence of the 3, 6, and 9, then you would have a key to the universe.
