Why is the sky dark in the night?
Because the earth is facing away from the sun, making the earth in between us and the sun. This is more of a puzzling question than you might think, since the beginning of time astronomers have been wondering why the night sky is not as bright as the noonday sun, as there are billions of stars in the sky to light it all up. This subject was popularised by German astronomer Heinrich Wilhelm Olbers in the 19th Century and is now known as Olbers Paradox. Since Edwin Hubble's time, astronomers have calculated that the universe must be expanding, and is not infinitely old so the light from very distant stars can never reach the Earth, meaning that the night sky will be dark.

How do we know that the Universe is expanding?
The main evidence is the redshift of distant galaxies; the only sensible explanation is a cosmological redshift, related to an expanding Universe. Other pieces of evidence are the microwave background radiation, which agrees very well with the predictions made by the Big Bang theory, and Olber's paradox - among others.
When was Olber's Paradox popularised?
References to what is now known as Olbers' Paradox date back to the 1500s. This paradox has come up periodically in history. In 1929, Edwin Hubble discovered that the universe is expanding, which offers an explanation to the paradox. Prior to this, any hypotheses were quickly dismissed.
What is olber's paradox question?
Olbers' paradox is a question about why the night sky is dark if the universe is infinite and filled with an infinite number of stars. The paradox arises because if every line of sight in the universe eventually intersects with a star, then the night sky should be as bright as the surface of a star.
How would things be different if interstellar matter didn't absorb starlight?
Yes - the night sky would be yellow-white (Olbers' Paradox)
Why the space is dark in spite of billions of stars?
Because the universe is neither infinitely large nor infinitely old. If you need more details, look up "Olbers' paradox".
Why is space is dark in spite of billions of stars?
Because the universe is neither infinitely large nor infinitely old. If you need more details, look up "Olbers' paradox".
How does Olbers' Paradox relate with the Big Bang?
If our Universe were infinite both in size and age, then our entire sky would, by necessity, be filled with light at all times. That it is not is Olber's Paradox -- and indication that our Universe must be finite in either size or age. The Big Bang was a hypthesis that it was finite in age; and every prediction made by the BB that has been tested has supported the hypothesis.
Why the sky is dark at night?
The sky is dark at night because the Earth turns, causing one side to go into the shadow of the Earth, making the sky dark. Comment : I think this question is about "Olbers' Paradox". The answer is still a bit controversial, but most astronomers agree that the sky is dark at night because of the "Big Bang" that started our Universe. The most important facts involved in the explanation are: 1) The Universe began about 13.7 billion years ago. 2) The Universe has been expanding since it began. 3) Light has a finite speed. Look for "Olbers' Paradox" if you want a detailed explanation. In fact Wikipedia has a useful page called simply "Olbers' Paradox".
