The sky is blue due to raleigh scattering of visible light, and blue is scattered the least - so it's more evident
I think I heard space starts at 200,000ft...not sure if I got that right....normal cirrus clouds are about 25,000ft-35,000ft

When sunlight travels through the atmosphere, blue light scatters more than the other colors, leaving a dominant yellow-orange hue to the transmitted light. The scattered light makes the sky blue; the transmitted light makes the sunset reddish orange.
Our best guess suggests the universe probably has a slight curvature. Stephen Hawking referred to this in his description of a finite, but unbounded universe.

Some one told me once that the sky is blue because it's a reflection from the sea - the most space consuming thing on earth. So that's what I've always believed.

a better question is why is the sky not blue at night, and why does it change colors throughout the day? Also, can the sky really fall down. If it can does it all fall at once, or in tiny chunks.

Sky is not a physical object. The 3-dimensional space is called sky. Sky has no color, it is the presence of sun that makes it colored mosly blue. Sky, materially, has not limit.

Light bounces off the moisture in the air (sky) and reflects only blue light... when light color reflects it only shows that color so the color of any object is that color being reflected when white light goes onto it.
And the universe never ends

The sun reflects light of of the gases that are in the atmosphere and they happen to reflect the color blue.

Because when light passes through the atmosphere it's scattered. blue light is scattered the most, that's why.
it does not end

it is due to the scattering of sun light when it travells from the sun to the earth ................ only blue remains when the light reaches the earth
the case is differnt in morning and evening
