Question: Do You think that science could ever change the sky and how????

Science always changes the sky! 😀 We go from day to night, and the stars appear to move around the sky as the Earth rotates on its axis.
Do you mean could we change the colour of the sky? Our sky looks blue because the atmosphere scatters light from the sun, and blue is the colour which is scattered the most. As the Sun gets lower in the sky, its light is passing through more of the atmosphere to reach you. Even more of the blue light is scattered, allowing the reds and yellows to pass straight through to your eyes. That’s why we get red sunsets.
The atmosphere on Venus is really thick, and made from mostly carbon dioxide, nitrogen and sulphur dioxide. We think the sky on Venus is probably not blue but orangey-red.
