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?

- MMSHannahS313년 이하In this article, 'The Real Reason Skies Go Dark After The Sun Sets' is obviously about why the sky goes dark after the sun sets. But it questions why isn't it bright if their are so many stars out "there"? It states that since there are so many stars and that space is always expanding, the stars sort of stretch with the expanding space. The farther away they become from earth or any planet, the redder they become. And at one point they become so very red that they become black and it has a specific name; "infrared". This leaves me wondering of why do they become red? Why not pink or yellow or any color? It is an amazing theory, not because it gives you a simple answer of why the sky turns dark, but why it doesn't turn bright if their are so many stars that somehow fill space.
jiyoon244613년 이하Wow, how fascinating! This is an interesting article. Guys! Post some comments here.- swapmeet13년 이하This guy should make more minute physics, it would make science SOOOOOOOOOO much easier to understand.
- MMSkaitlyn24913년 이하this article is about space and why it gets dark at night. The universe is practically pushing the stars back. So that would mean that in millions of years from now you wouldn't be able to see any stars in the sky unless you use a infrared telescopes. I thought this article was cool because i've never really thought of that question before. Now that I know about this I might even tell some of my relatives about it.
- MMSEmilyB1113년 이하I think that it is cool that some people think stars are blocked by dust because the sky at night isn’t shiny, but the sun will have to be blocked by dust too because the sky in during the day isn't shiny. I think it’s a cool fact that you cannot see any light behind the stars. The reason we see that the sky is dark at night is because the stars block any light that is behind them. I think it’s cool and sad that the Universe is growing bigger and it's pushing the stars father back so in a million years people won’t be able to see the stars. I think this article is very interesting and filled with cool facts.
- hi13년 이하confusing...
bananakiller13년 이하uh... the earth turns on its axis and the stars cant lite up the sky cuz the milions of miles away- ashly13년 이하oh okay, there must be another thing involved in this I'm still confused it doesn't make any sence.
southernbelle13년 이하it makes sense. the universe is expanding, so stars get farther away all the time. the farther they get away, they turn red--INFARED. we cannot see infared light w the human eye. the farther we look with a telescope we see the older parts of the universe. THEREFORE the sky is dark.
tavian13년 이하youre right
- me13년 이하whoops i feel there is something else to this
- me13년 이하for some reason i feel that there of this that we just dont understand and get. there is more than we think out there.
