Image Of India on Diwali Night by NASA

the original source of image is HERE

This photo has been taken by the satellite of NASA on DIWALI night. Its India our motherland , see the beauty at the night of Diwali 'THE FESTIVAL OF LIGHT' a most important festival of India.The whole country enjoy this day fullest Diwali with lights, blessings and love.

But I think this image expressing some more information , This probably represents Economic growth. The areas that are dark Bihar, North Eastern states are the areas in India which are comparatively backward in terms of economic growth, whereas the brightest lights are in the metropolis. The areas that are dark also represent a very large part of the population, I'm not sure about the varying colors, but that seems like the most logical explanation.Sometimes I think this image is most certainly not of Diwali. For one, the idea of different regions celebrating with different colored lights is ridiculous. Some people have claimed that the colors are because of the fireworks that fill the sky on Diwali night. But that doesn't explain why the illumination is brightest along the Indus river in predominantly muslim Pakistan--Diwali is a hindu festival, also see the Srilanka its glowing lights more than India as per my idea srilanka doesn't celebrate Diwali and see the Bangladesh its glittering with lights, I am confused, please write some lines what do you think about this image?
