One simple question : How many stars can you see from naked eye in a clear sky ?
Its 2137 .
Your answer might be infinite.
And I am glad to tell you that you are absolutely wrong.
People around the world have no idea where science have reached and the above question is one of such example.
Question is an example heard first time. Alright let me explain the fact.
Answer of the above question is 2137, a human can only see 2137 stars from naked eyes in clear sky.
After discovering the range and possible visible spectrum of human eye scientists calculated that there are only approx. 8548 stars visible to human eye from the earth surface.
Now as we all know that earth is a sphere.
This means only 4274 stars are visible from each northern and southern hemisphere.
A human can only be at one half of that one hemisphere. This results in 2137 stars from any point on earth.
Now you do know the answer and reason.
So next time whenever you’ll be asked the same question.
Give them a valid answer with a solid reason.
DO GOOD HAVE GOOD.
