In Rigveda, following sloka’s state about the speed of light which is nearly about of modern value of 186,282.397 miles / seconds: “ Yojananam Dwe Dwe Shate Dwe Cha Yojane Aken Nimishardhena Krammana Namostute” (Rig-veda I,50-4) In the verse Sun light speed is measured with the help of units called Yojan & Nimesha.This verse explain that sunlight moves 2202 Yojans in Half Nimish. Taranir Vishvadarshato Jyotishkrdasi Surya | Vishvamaa Bhaasirochanam || Meaning: Oh Sun! (You) overwhelm all in speed, visible to all, source of light.

Distance travelled =2202 Yojanas 1 Yojana = 9 miles, 110 Yards =21,144.705 miles (Apprx) Time taken 1/2 nimesha = 0.114286 seconds(Apprx) Speed of light= 185,016.169 miles / seconds. Modern Value= 186,282.397 miles / seconds. Modern science claims the speed of light to be aproximately 186,282.397 miles / seconds Unit of Time: Nimesa Nimesa Definition as per Moksha dharma parva of Shanti Parva in Mahabharata 15 Nimisha = 1 Kastha 30 Kashta = 1 Kala 30.3 Kala = 1 Muhurta 30 Muhurtas = 1 Diva-Ratri (Day-Night) One Day-Night = 24 hours Unit of Distance: Yojana Yojana Definition as per “Vishnu Purana” 10 ParamAnus = 1 Parasúkshma 10 Parasúkshmas = 1 Trasarenu 10 Trasarenus = 1 Mahírajas 10 Mahírajas= 1 Bálágra 10 Bálágra = 1 Likhsha 10 Likhsha= 1 Yuka 1o Yukas = 1 Yavodara 10 Yavodaras = 1 Yava 10 Yava = 1 Angula 6 fingers = 1 Pada 2 Padas = 1 Vitasti 2 Vitasti = 1 Hasta 4 Hastas = a Dhanu, a Danda, or pauruSa (a man’s height), or 2 Nárikás = 6 feet 2000 Dhanus = 1 Gavyuti = 12000 feet 4 Gavyutis = 1 Yojana = 9.09 miles Now, you may also want to read… Color and speed of light ||It says sun light travels 2202 Yojanas in a half Nimesa.
