The following links claim that there is evidence of the correct speed of light in a Rig Veda Commentary:

Quora: Did Sayana know the Speed of Light

Speed of light in the Rig veda

In the hymn, the author pays respect to the one who moves 2202 yojanas in half a nimish

The metric conversions to support this are:

1 yojan = 4 kose

 

1 kose = 8000 British yards

 

1 British yard = 0.9144 m.

and

In the Shrimad Bhagavad:

 

15 nimishas = 1 kashta

 

15 kashtas = 1 laghu

 

30 laghus = 1 muhurta

 

30 muhurtas = 1 diva-ratri

If these conversions and the hymn are true, then the claim follows (Speed of light under these conversions and using the hymn calculated as 302031036.422 m/s, which is very accurate)

• Is the hymn by Sayana in the 13th-something century
• Are the conversions correct?
