Olber's Paradox is based on the assumptions that the universe is infinite in size, both in space and time, and that it is uniformly filled with stars. These assumptions lead to the conclusion that the night sky should be as bright as the surface of a star due to an infinite number of stars in every line of sight.

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.
What is the central question in Olber's paradox?
The central question in Olbers' paradox is why the night sky is dark if the universe is infinite and filled with an infinite number of stars. This paradox raises questions about the distribution of matter in the universe, the age of the universe, and the nature of light.
What is the solution to the paradox?
The solution to a paradox is often found by reexamining the assumptions or logic behind the conflicting ideas, and finding a way to reconcile them.
What is paradox argument?
A paradox is a statement or situation that seems contradictory or self-defeating, but may actually reveal a deeper truth. In an argument, a paradox can challenge traditional assumptions or logic by presenting two seemingly conflicting ideas that both appear to be true. This can lead to new insights or perspectives on a given topic.
Features of paradox?
A paradox is a statement that appears self-contradictory or absurd but may actually be true. It often challenges common assumptions and leads to deeper reflection on the nature of reality or logic. Paradoxes can be found in various fields like philosophy, mathematics, and logic.
What assumptions are made in Olbers' paradox?
In Olber's paradox, the 2 most important assumptions made were 1) The Universe is infinite. 2) The Universe is static and infinitely old.
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.

How would things be different if interstellar matter didn't absorb starlight?
Yes - the night sky would be yellow-white (Olbers' Paradox)
What is the solution to the paradox?
The solution to a paradox is often found by reexamining the assumptions or logic behind the conflicting ideas, and finding a way to reconcile them.
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 does the Olbers paradox suggest that the night sky is dark despite the countless number of stars in the universe?
The Olbers paradox suggests that the night sky is dark despite the countless number of stars in the universe because the light from distant stars may not have reached us yet, or it may have been absorbed or scattered by dust and gas in space. This means that not all the light from all the stars in the universe reaches Earth, resulting in a dark night sky.
How is Olbers' paradox resolved in the context of the expanding universe and the presence of cosmic microwave background radiation?
Olbers' paradox is resolved in the context of the expanding universe and the presence of cosmic microwave background radiation by understanding that the universe is not infinite in age or size. The expansion of the universe causes light from distant stars to redshift, making them fainter and cooler, and the cosmic microwave background radiation fills the universe with a uniform glow, accounting for the darkness of the night sky.
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".
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.
