Why is the sky blue
all I know the sky is beautiful and I like it
That's how god made it
Why is an apple red? It's all about perception.
If you look through more than two miles of air it looks blue . . . that's its color . . .
Because it's sad.
The gasses in the layers of the atmosphere filter out all other colors.
Simply, it is due to the fact that the gas, Ozone, which inhabits our atmosphere, primarily reflects blue light. But, this is only seen in really bright light. (hence nightime and why the sky looks paler on less bright days)
WTF the sky is blue? its been gray to me all my life
