Why does the sky go dark at night? You are all probably thinking that this is a question even a kindergartner can answer - The simple answer and the one that is pretty obvious is that as the Earth rotate on its axis it moves away from the sun and therefore, causes the skies to go dark. Sounds logical to us but what about the zillions of sparkly stars? Why don't they pitch in and make the sky all shiny?

- Savannah S.12년 이상two things i learned were, that the universe is expanding and that in a billion years people might not be able to see stars except through an infrared telescope.
- leila v.12년 이상One fact I learned was that our universe is 13.7 billion years old. Another fact I learned was our universe is pushing the stars away. My opinion on this is the stars are so bright that we can see them.
- Savannah12년 이상This is really cool! I never knew that there were so many different possibilities for why we can see stars and the moon at night, or even if the sky is truly dark. It informed me of all the things that the scientist are doing in our universe every day to learn and teach us new things.
- Michelle K12년 이상Our universe is 13.7 billion years old and that the ever growing universe is pushing stars away and thats why the skies go dark. I think its quite unteresting that the universe is still growing and i want to know if it has an end now.
- Justin12년 이상Did you ever wounder why the sky goes dark at night? Well there is a perfectly good explanation for that. At first astronomers use to think it was because it was dust. But not far after they discovered that the dust would effect the sun also so that theory was wrong. Their next theory was that almost all the stars where where stacked behind each other we all know that theory is wrong but they did not. as soon as they found out that was wrong they found out that it had to be that it had to be distance. That's why the sky gets dark at night.
- David12년 이상I wonder how scientists figured out that the movement of earth didn't cause the sky to turn to turn pitch black. First, the sky turns pitch black at night. The sky turns pitch black because at the edge of the visible univers it is pitch black causing the night time sky to look black. Second, You could ask a kindergarterner why the sky turns black at night they would '' Because earth spins like a top''. Really Heinrich Olbers discovered that it is because of the edge of the universe. Scientists discovered that the night time sky is because of the edge of the universe
- Greg12년 이상That would be really boring if there were no stars in our render distance. One reason is that many people like to watch the stars laying on a hill but if we could not watch the stars we would have lot less creativity. That is why we would be really bored.
- George Wang12년 이상Wow, I never thought of that. I'm the scientist in my grade, though.
- Ali s12년 이상how cute!!!:)
