Question

why is the night sky dark?

Answer 1

well.. you should really look at

"why is the night sky dark from minutephysics" video . that ll give you aminute explanation of it ;-)

Answer 2

Because it's facing away from the sun.

Unfortunately, the sky isn't dark enough.

Since the invention of power transmission and artificial lighting, light pollution has spoiled the darkness with a constant foggy haze, and we are now denied the simple glory of dark skies at night.

And it just keeps getting worse.

Answer 3

not as much light around

Answer 4

interesting answer from minutephysics, @mashy
While a few things are on point like the scattering that gives the answer why the sky is blue or whatever, I just don't think the answer was sufficient or it is my inability to completely understand the answer it gave. Or perhaps it is because the explanation was dumbed down too much for my taste.

Answer 5

The reason anything is dark or black is that it is neither emitting, reflecting or scattering light in your direction.

Answer 6

The question is .. why is the night sky dark?? because there are billions and billions of stars everywhere.. so why is it dark? regardless of whether we had sun or not.. atmosphere or not.. it shouldn't have been dark
the answer what minutephysics gives is this

Even though there are many starts.. some are so far, that light hasn't had enough time to reach us yet.. from the beginning of the big bang..

and secondly universe is accelerating.. which means red shift takes place.. starts which are very far away are going away from us faster.. and hence get red shifted more.. and goes into the infrared region.. !

i seriously do believe its the second reason.. ! cause if you use an infrared cam.. you can always detect radiations.. strong radiations everywhere! all the tiem!

Answer 7

Friends please help me as my problem is so big and i get this website now,
I was a student of State board & recently in standard 11 my college board has been changed to CBSE due to which there was no teacher to teach us,
U all can understand that how hard CBSE is please let me know how can i study so that i can get good marks in physics ,
My exam is on 5th march
And i have not prepared yet till now due to all these
With these i dont go to any coaching or tutions.
Please help me!

Answer 8

a simple explanation is , anything that we can see is because of light reflect from that object, like when you are in a dark room you cant see anything because none of the object receives light therefore no reflection similarly at night there is no light so there is no reflection and hence it appears dark
