Speed of light in Rig Veda ???

Did Indians knew the speed of light before 1000BC??

The answer is yes. as you can see the above image there is a sentence "The suns rays travel 2202  yojanas in just half a Nimisha".

• In the above sentence yojanas are the unit of distance and Nimisha is unit of time.
• If we convert yojanas into miles we get 1yojana =9.09miles.
• Conversion:

Yojana is defined in Chapter 6 of Book 1 of the ancient Vedic text “Vishnu Purana” as follows

• 10 ParamAnus = 1 Parasúkshma
  10 Parasúkshmas = 1 Trasarenu
  10 Trasarenus = 1 Mahírajas (particle of dust)
  10 Mahírajas= 1 Bálágra (hair’s point)
  10 Bálágra = 1 Likhsha
  10 Likhsha= 1 Yuka
  1o Yukas = 1 Yavodara (heart of barley)
  10 Yavodaras = 1 Yava (barley grain of middle size)
  10 Yava = 1 Angula (1.89 cm or approx 3/4 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 Gavyuti (distance to which a cow’s call or lowing can be heard) = 12000 feet
  4 Gavyutis = 1 Yojana = 9.09 miles

Conversion of Nimisha into seconds:

• 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 nimisha = 86,400 seconds
  1 time = 0.2112 seconds (This is a recursive decimal! Wink of an eye=.2112 seconds!)
  1/2 nimisha = 0.1056 seconds
• Now let's find the value of speed of light according to rig Veda:

Wkt 2202 yojanas per 1/2 Nimisha

=2202*9.09 miles per 0.1056 seconds

=20016.18 miles per 0.1056 seconds

=189547 miles per sec!!!!

As per modern research speed of light is about 186282 miles per sec.

There is some difference because we made some approximation in the conversion of yojanas into miles 

 Anyhow it is mind-blowing that speed of light was discovered before 1000BC By Indians.

Proud to be Indian 🇮🇳🇮🇳🇮🇳

Jai hind.
