Speed of light

Sayana (1315-1387) was a minister in the court of King Bukka I of the Vijayanagar Empire in South India; he was also a great Vedic scholar. In his commentary on the fourth verse of the hymn 1.50 of the Rig Veda on the sun, he says:

Tatha cha smaryate yojananam sahasre dve dve shate dve cha yogane ekena nimishardhena kramamana namo ‘stu ta iti


Thus it is remembered: (O Sun), bow to you, you who travers 2,202 yojanas in half a nimesha.

Unit of Time: Nimesa
The Moksha dharma parva of Shanti Parva in Mahabharata describes Nimisha as follows:
15 Nimisha = 1 Kastha

30 Kashta = 1 Kala
30.3 Kala = 1 Muhurta
30 Muhurtas = 1 Diva-Ratri (Day-Night)

We know Day-Night is 24 hours So we get 24 hours = 30 x 30.3 x 30 x 15 nimisha

in other words 409050 nimisha

We know 1 hour = 60 x 60 = 3600 seconds

So 24 hours = 24 x 3600 seconds = 409050 nimisha
409050 nimesa = 86,400 seconds
1 nimesa = 0.2112 seconds (This is a recursive decimal! Wink of an eye=.2112 seconds!)
1/2 nimesa = 0.1056 seconds

Unit of Distance:
Yojana is defined in Chapter 6 of Book 1 of the ancient vedic text “Vishnu Purana” as follows
10 Paramáńus = 1 Parasúkshma
10 Parasúkshmas = 1 Trasareńu
10 Trasareńus = 1 Mahírajas (particle of dust)
10 Mahírajasas = 1 Bálágra (hair’s point)
10 Bálágras = 1 Likhyá
10 Likhyás= 1 Yúka
10 Yúkas = 1 Yavodara (heart of barley)
10 Yavodaras = 1 Yava (barley grain of middle size)
10 Yava = 1 Angula (finger, or inch)
6 fingers = 1 Pada (the breadth of it)
2 Padas = 1 Vitasti (span)
2 Vitasti = 1 Hasta (cubit)
4 Hastas = a Dhanu, a Danda, or pauruSa (a man’s height), or 2 Nárikás = 6 feet
2000 Dhanus = 1 Gavyúti (distance to which a cow’s call or lowing can be heard) = 12000 feet
4 Gavyútis = 1 Yojana = 9.09 miles

Calculation:

So now we can calculate what is the value of the speed of light in modern units based on the value given as 2202 yojanas in 1/2 nimesa = 2202 x 9.09 miles per 0.1056 seconds = 20016.18 miles per 0.1056 seconds = 189547 miles per second !!



The speed of light is 186282.397 miles per second as per modern estimates.
