The sky is blue because thats how it was made, don\'t worry about the fact we are in a cave!
LOL...
\"The chicken arrived at 10:31 a.m. Wednesday. The staff at the post office told me that this was the first chicken anyone had mailed to the James A. Farley General Post Office in recent memory, and perhaps ever.
The egg arrived that same day, at 9:37 p.m., eleven hours after the chicken.
It has now been empirically determined that the chicken came first, the egg second.
However, seeing the history of previous questions that were taken up first by philosophers and only later by scientists, I am loath to predict that these results ? clear as they are ? will settle the question to everyone?s satisfaction.\"
A joke on the question :p
Back on topic: The crystal reflects the daylight. Therefore, the sky would be blue because that is the reflection, am I right?
