Eclipses scientifically explained in Rig Veda
There are many myths across many cultures about how eclipses occur.
In Rigveda (5-40-5 to 9), seer Atri explained scientifically why eclipse occurs.
Puranas have described the story of Rahu, Ketu (North Node and South Node of Moon) in a mystical way.
But the essence remains same as in Rig Veda, which was composed more than 23,000 years ago.
The sage here described how Svarbhanu created eclipses of Sun and Moon and how Sun appeared after eclipse in sky.
Svarbhanu is Sva + Bha+ Anu. Sva means sky. Bha means light. Anu means follower.
Follower of light is shadow, which is present in the sky.
Eclipse is seen due to this shadow. It is a miracle or phenomenon and Asura means the same (not demon).
Stephen Hawking states that, according to Viking mythology, eclipses occur when two wolves, Skoll and Hati, catch the sun or moon.
At the onset of an eclipse people would make lots of noise, hoping to scare the wolves away.
After some time, people must have noticed that the eclipses ended regardless of whether they ran around banging on pots.
