Post by: neilep on 23/11/2007 06:27:50

Dear Skyologists,

In the early days..before plants and life....what colour schemes has the sky been through ?....say...from four billion years to the present day would be nice !!





Ewe Are My Sunshine
My only sunshine.
Ewe make me happy
When skies are grey.

before the earth had the atmosphere that is does today, it was probibly a reddy brown colour like mars, then when volcanoes spwed ash and stuff it posibly was black, then as plants began to appear it slowly changed to blue. Short, sweet, simple answer....right? who knows!
