Outer space is so big, but why can't we see the balckness of space?

    reflection of light

    During daylight the sky has the appearance of a deep blue surface, but this is the result of the air scattering sunlight. [1] There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day.

    on earth, the sky seems blue for the period of the day because of the fact easy strikes for the period of the ambience mutually with purple, orange and yellow easy. long wavelengths bypass right now with the aid of our atmosphere, however the quick wavelength easy is absorbed with the aid of the gasoline molecules – this absorbed easy is blue and it radiates in diverse guidelines. It gets scattered everywhere in the sky and reaches you – the viewer. That’s why we see the sky blue. This phenomenon is named Rayleigh scattering. on the different hand, out in area, there is not any atmosphere and as a result, no easy scattering. as a effect, the easy can’t attain a viewer on earth, as a result, the sky seems dark and black.

    Because the sun reflects of the atmosphere as it enters earth causing the sky to look black, thats why when the sun dissapears the sky turns black

    the nitrogen / oxygen mixture of our atmosphere filters out most bandwidths from the sun but not much in the blue bandwidths. At night there isn't enough light to be refracted.

    Well, the sky isn't really blue, it is a mixture of clouds and atomosphere.The reason we can't see past it is because there are five layers of atomosphere,the troposphere,mesosphere,thermosphere,and the stratosphere,(each about 80 miles long) and then it's space.So do you think you can see that far?Didn't think so.

    Because the atmosphere reflects (and refracts) the light of our sun. But you are correct - the sky is actually black.

  • Only the ultraviolet spectrum is viewable as the rest of the Suns light is reflected by our atmosphere. The color black is percieved when all light is absorbed. White is when all light is reflected.

    Refraction of light through the earth's atmosphere.

    we see the sky as blue because sunlight reflects off of air particles and they reflect a blue color (sky blue).
