Not necessarily true because if the ground wasn't there the sky still would be, although you can argue that the sky isn't there until the ground is removed hence that can potentially hold true. I think you have to look at the planets that are made purely of gasses and realise that some of them are essentially nothing but sky hence the sky itself _could_ be just a large sphere with a big ball of matter (yes, Earth) in the middle meaning it doesn't really start anywhere or at least, starts at the absolute centre of the sphere but ends at the boundaries of space.Amedor wrote:It starts where the ground stops .. so 0cm, 0inch, 0foot etc
Silly, but tricky question....
