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.
What else can I help you with?
Why is the sky blue if space is black?
Rayleigh scattering.
Why does the sky appear dark instead of blue to an astronaut?
Because the sky is blue to us by the light being scattered through nitrogen. In space there is no nitrogen for the light to scatter through, therefore the sky around them seems black. Although, when in space if you look at the earth, you can see the blue sky, as there is nitrogen there.

Why does the moon not have a beautiful blue sky in the day?
The blue of Earth's sky is caused by sunlight scattered in the atmosphere. When you get above the atmosphere, the sky turns black. The Moon has no atmosphere at all, and so the sky looks black at any altitude.
On the moon would the sky look blue or black?
On the moon the sky will look blue.

To an astronaut in a space craft, the sky appears to be black.
Why do astronauts in orbit around Earth see a black sky with stars that do not twinkle but see a blue earth?
Stars twinkle due to the scattering effect of earth's atmosphere. In space this is no atmosphere, thus they do not twinkle. The sky is black in space because there is no scattering of light as there is in the atmosphere. The earth appears blue from space due to the color of the gases in the atmosphere, and their reflected light on large bodies of water.
How high do you travel before the sky turns black?
Our sky is blue DURING THE DAY because of two things: 1) sunlight is entering our atmosphere 2) our atmosphere is thick enough to preferentially scatter blue light. If either (1) or (2) cease to be true, then the sky will NOT be blue. As night "falls," the sky does not go instantly from blue to black. Instead, less and less of our Sun's light is available to scatter, and thus the sky goes slowly from blue to black. It's the same way as you go higher and higher. There is no altitude at which there is simply no longer enough atmosphere to scatter enough sun light to give the sky a blue look. It is more the case that, as you go higher and higher, the sky becomes less and less blue -- just like at night "fall." For SOME idea of how our sky changes, check out a video of a space shuttle launch.
Is the sky black at night?
At night darkness emerges for which the sky seems to be black, though originally it is blue. The color blue is visible with the onset of dawn.
