The hint came from Solar Orbits. This also addresses how Indian's discovered Zero and Decimal System. This also establishes Indians knew Astronomy and Gravity well.
was a very interesting exercise. I was already given the clue:
"chan-chan." is "sun-sun" for it being a very ever sunny site.
I thought in Sanskrit, there would be sounds like that from where the sound for Sun came out. And I found two words.
word for Sanskrit Sun is "sunuu". And the word for verb "go" is "shun"
where "sh" is palatal and can also become "ch" or even "z", (English
letter 'x' is Sanskrit Compound Sibiliant 'kS' or 'ksh', Dental 's' is
'sa', Palatal 'sh', 'ch' or 'z' are 'z', and there is none for Sanskrit
The Sanskrit word for zero is "O" is
"shunya", and it looks like it looks like a circle and the attribute of
sun as orbit is "go-go" or perpetual going.
may have got the idea of Decimal System and Zero by looking at the Solar
Orbits and they completing perfect cycles before starting from scratch
or zero again!
