Why is the sky blue and not black like space?
1. Outer space contains virtually no gas/dust to scatter light. Outer space is black. 2. The sky is blue because that's the colour of air (mostly nitrogen), which is not totally colourless. You can see this effect looking at distant (10 km-plus) mountains. They have a blue tinge (caused by the intervening air between you and the mountains) known as atmospheric perspective. 3. If the sky's colour was due reflection from the oceans, then it would be white above Antarctica, which is snowy white. 4. If the ocean was blue because it reflects the sky, why does it still look blue-ish when under a totally clouded-over sky? The ocean is blue for the same reason the sky is blue: the sky is blue 'cause that's the colour of air, the sea is blue 'cause that's the colour of water.
