It is dark everywhere at night, the whole sky looks black. But as soon as the sun rises in the morning the sky turns blue. Light fills everywhere. But this does not happen with space. There is darkness everywhere even after the sun is there. Now the question arises that why this happens. When the sky of the earth can appear blue with the light of the sun… then why many suns present in the space are not able to give light to it. Let’s try to understand what is the science behind it.
Why space appears black
Actually, there is a simple theory behind it. The color of the sky appears blue to us because when the sun’s rays enter the earth’s atmosphere, due to the scattering of light and due to the dust particles present in the atmosphere, this light spreads all around and the color of the sky appears blue. seems to give. There is neither an atmosphere in space nor the scattering of light. This is the reason why space always appears black. This makes it clear that if there was an atmosphere in space like Earth, there would be scattering of light and possibly the color of the sky could appear blue there too.
Eyes also have a roll
It can also be understood with an example. You understand it in such a way that when we light a torch in a dark room, its light does not directly reach our eyes, but in spite of this we know that the light of the torch is spreading in the room. This happens because when the light of the torch collides with the dust particles present in the room and creates an image and that image reaches our eyes, then we feel or see that the light of the torch is spreading in the room. Same thing happens with space. There is definitely sunlight in the space, but there is neither an atmosphere nor the scattering of light…that’s why our eyes see the space as black.
