When someone asks why the night is dark, most of us tend to blow it off as a stupid question. After all, it's dark simply because the sun's light is not able to reach us, right? How simple! Actually, that explanation doesn't quite cover everything. What most of us miss out on is the fact that the billions of stars in the sky fail to light up the night sky, while, during the day, it just takes us one star - the sun - to brighten the whole world up! And so, when we think of it this way, we realize that there is a paradox lying in this situation. This is known as the 'dark sky paradox,' and it was posed a couple of centuries ago. A solution too was found to this paradox, but it wasn't until now that it was actually proved to be true.
Check it out!
But have you ever wondered why it is dark, despite being filled with billions of stars that shine bright?
The paradoxical situation of this phenomenon is not very apparent, but it makes a lot of sense when thought about!
In the day, we need only one star- the sun - to brighten up the world. Then, in the night, why are the billions of stars not able to do the same?
Heinrich Olbers was the one who brought this paradox to light. However, during that time, not enough attention was given to the depth and importance of this paradoxical olbers.
He said that clouds of Hydrogen lying between us and the stars are the reason why sufficient light is not able to reach the Earth, and so, the billions of stars in the sky are unable to light up the sky.
The stars we see are only a small fraction of the billions of stars that're actually out there.
With the help of modern technology, Olbers' theory has finally been proven correct! So, now we know who to blame for the darkness of the night sky. Hydrogen clouds!
