The Horrible Cosmic Mysteries of the Night Sky, Olbers' Paradox (or Why is the Dark Not Bright?)
If you have ever gazed at the stars in wonder, then perhaps your thoughts turned to why it is that despite an infinite expanse of sky with trillions upon billions of galaxies each holding untold star systems there are fewer lights on a clear night than leaves in any given forest? This mysterious question was Olbers' Paradox, which had kept astronomers scratching their heads for centuries. I have tried to elaborate on the behavior we are facing right now and a deeper dive into this paradox; however, before moving further down reading about our heuristic behaviors I would encourage you all go through above video display of human brain where in move slide for visuals using linguistic representation [2]. Hopefully this will give us a better view of the universe and its purpose. You should read this article first what is paradox? So Here Is Quite Simple Way To Explain
What is Olbers' Paradox?
Anyone who would listen in 1823 (including German astronomer Heinrich Olbers) that if you took an infinite universe and set it up so uniformly with stars - every line of sight from us ended on a star somewhere - your night sky would be as bright as the sun. This however is not in line with the dark night sky that we see. This is the paradox: since there are an infinite amount of stars in this universe, everything in the sky should be shining. This existence proves that there is an anthropology which resolves this paradox,
What About Olbers' Paradox (The Possible Solutions)
Through the years, many solutions to Olbers' Paradox have been based on different concepts of how the universe actually is. Follow the link to read some of these top-highlighted solutions
The Universe is Not Infinitely Big: One answer to this paradox is our universe itself isn't actually infinite. If the universe is not infinite, then there could be a reasonable amount of finite stars which might still give all light to fill in the sky. This is why the night sky appears dark.
The Universe is Lumpy, Also Another possible answer might be that the universe does not contain a uniform distribution of stars. No, instead there are regions where no stars exist at all and therefore it is a dark night sky. This is supported by the fact that galaxies are not uniformly spread throughout space.
The optics are redshifted from our point of view way back in time to the source: This obviously would create an obvious wave solution, undetectable even using light unless we had digital movie technology. This might explain why the night sky is dark.
The Age of the Universe - Believers note that because light from distant stars requires anniversaries to procreate if we allow for a finite age of this universe then light simply hasn't had time yet! That is, the dark sky we have could instead be due to not enough time has passed for us to see light from all those stars.
We can interpret this as an informal statement of Olbers' Paradox.
Olbers' Paradox has been taken to mean different things by others, yielding diverse propositions about the universe's makeup. Some of the most standout reimaginings are as follows:
Static Universe Hypothesis: A hypothesis that assumes the universe, i.e., space and time are static; they never change, disturb, or fluctuate. This is in harmony with a Universe that has an edge, so saying that the stars have all shone down upon every corner of the sky.
The Steady State Universe Hypothesis: This hypothesis only maintains that the universe is expanding (obviously an idea in accord with observation) and suggests further, but far less straightforwardly argument, that matter must be created as continual to widespread filling about us left lightyears larger places formed by cosmic expansion. This in turn implies that stars and galaxies are forever being produced, which will keep the night sky from becoming aglow endlessly with other cosmic bodies.
Big Bang: According to this theory, the universe started off as a singularity and has been expanding ever since. This understanding is supported by the observed cosmic microwave background. The Big Bang theory also accounts for the redshift of distant starlight (i.e. light emitted from stars located very far away now appears so highly redshifted and faint that their observation is not possible).
Olbers' Paradox Isn't Just About the Observed Blackness of Space
It has been a Paradox simple in its nature yet gave mankind the realization and direction to search for more. Through examination of different possible resolutions to the paradox and interpretations, astronomers have used its respective implications to hone their understanding of each facet (size, composition age) of the universe. That even seemingly simple questions can provide a profound understanding of the universe (and probably loads more for us).
Even today, astronomers and physicists continue to research Olbers' Paradox and seek out new means by which to examine the multiple solutions/interpretations of this paradox. Hopefully, as technology continues to advance and we collect more observational data on these stars, a solution will be within our grasp.
BIG BANG HYPOTHESIS AND OLBERS' PARADOX
The Big Bang Hypothesis is the most conventional explanation of Olbers' Paradox. Together, they account for the cosmic microwave background radiation, that picture of the flash from when we were born. According to this theory, the universe has been expanding since its beginning as a singularity. Since galaxies and other star systems are moving away from us, when we measure the light coming to use here on Earth everything is already in motion - a phenomenon Courtney explains as redshifting. Is this the reason why our night sky is dark, despite there being countless stars in the universe.
Evidence for the Big Bang
The hypothesis has been supported by a wide range of observations, including the location and relative quantities of helium in the universe (produced as predicted during Big Bang nucleosynthesis), the cosmic microwave background radiation anisotropy,[9] large-scale structure observed today, Alber's paradox[10] and Hubble diagram.[11][12 As well as this it has also been used to accurately predict the large-scale structure of the universe, galaxy formation, and cosmic voids.
The solution to this apparent paradox is that the universe has not been around forever, but was created at a finite time in the past; this answer dovetails nicely with observations indicating an expansion of space.
Olbers' Paradox also gave us a greater knowledge of the age of the cosmos. This paradox assumes an infinite age of the universe but light from stars that are very far away has had only a finite time to reach us. Astronomers estimated the age of the universe, to be approximately 13.8 billion years old using redshift measurements of distant galaxies and Cosmic microwave background radiation.

He found that Olbers' Paradox has been resolved using the right new physics to know what 95 percent of the universe is made out. We now know that regular old stars, planets, and gas are only a tiny slice of the cosmic pie. Except for dark matter and dark energy - which don't emit light, so are invisible to telescopes. The discovery of dark matter and energy is a significant development as it has opened up a whole new range of questions regarding the very nature universe.
