the sky is not actually blue it is just a reflection of the sun's light on the universe or blanket of sky. this is just my theory

No, that's not the answer. It's due to Rayleigh scattering. You don't need to make up new theories that you can't back up if we already know the answer.

The Earth's sky is blue because the air molecules (largely nitrogen and oxygen) are much smaller than the wavelength of light. When light encounters particles much smaller than its wavelength, the scattered intensity is inversely proportional to the 4'th power of the wavelength. This is called Rayleigh scattering, and it means that half the wavelength is scattered with 2**4 = 16 times more intensity. That's why the sky appears blue: the blue light is scattered some 16 times more strongly than the red light. Rayleigh scattering is also the reason why the setting Sun appears red: the blue light has been scattered away from the direct sunlight.

You must be new to yahoo answers because that question has been asked many many times. You should know that the sky is blue in the wavelength of light in which human eyes see. Some insects like bees for example see colors in a completely different manner. You could argue that the sky is only blue only to us humans.

The sky is blue because longer wavelengths bounce off the surface of the earth and radiate back in to space while shorter ones are absorbed by our mostly nitrogen based atmosphere. This is why the sky appears red at sunrise and sunset. Because the longer wavelengths have more atmosphere to travel through and thus more of the longerwavelengths are absorbed.

What a geek!!!! Naw, that guy above me who wrote approximately "debris interior the ambience ...blah blah blah ... Isaac Newton... blah blah blah ...John Tyndall in 1859." is obviously too huge of a nerd to have confidence or beleive. I assure you Isaac Newton did no longer make the sky blue because of the fact some guy no person ever heard of named "John Tyndall" informed him too. this is ridiculous! The sky is blue because of the fact air is obvious and outer area is blue (merely like the sea) - once you're staring on the sky, because of the fact the air is obvious, which ability you get to establish each and each of how into outer area ...this is blue. this is why the sky is blue. So enable's come again to Mr. Nerdy, shining his blue mild into the mixture of milk and cleansing soap (yuk!!!) till he have been given a crimson-eye alooking back at him. And that total goshdarn dissertation on "Lord Rayleigh" who studied the colour of sunshine reflecting off his **** till his techniques went inversely proportional to the fourth ability of his sufficiently small puggle ... huh? wha'? Ya lost me! airborne dirt and dust or Molecules? enable's see ... i will take the molecules please. Tyndall and Rayleigh the two informed me that concept that "Mark ok" is unquestionably one of those individuals who has a moist, hazey techniques that desires greater oxygen and nitrogen to account for the scattering of his techniques. Einstein in 1911 calculated that "Mark ok" is a finished nerd and Avogadro agreed. Why no longer violet? because of the fact it is gay this is why. .

To get to the other side. Now, what is the question? BTW: what is the blanket of sky made out of? Can I get one for my own use?

So why is water blue when you look at the ocean, but colorless when you hold it in your hand?
