Men of older generation used to say that all knowledge is
there in the Vedas. Anyone who hears such words will have
the first reaction that it is an over confident statement.
The Rig Veda Bhashyam by Sayana Madhava gives the following
Sloka praising the Sun:
"Yojanam sahasre dve, satadve, dvecha yojane
Ekena nimeshardhena kramamaana namosthuthe".
Two centuries before him, Adi Kavi Nannaya wrote a Telugu
sloka to give the same meaning.
One Yojana equals 15788.8 meters, and half of Nimesha
equals 8/75 fraction of a second. This gives the velocity
of light as 325940 km/s. We have to remember here that the
above value is an approximate one intended for easy
remembrance, like remembering the value of pi as 22/7. It
is better than the value 215000 km/s given by Danish
astronomer Ole Roemer in 1676. The word
"kramamaana" means that the velocity of light changes
over millions of years, and not an universal constant.
Can any person suggest an experiment to prove this?
