- Then you were not paying attention. They turned out this way so you
- could ask a question that cannot be answered to your satisfaction.
-
- A statement that explains how electromagnetic radiation is scattered by
- the atmosphere that is necessary to sustain carbon-based life *is* an
- answer to the scientific (this is sci.physics remember) question of
- why the sky is blue. If you do not like this answer, you should ask
- it somewhere else:
-
- An astronomer might observe that most of the time the sky is black,
- not blue, and wonder why your question was so narrow. It is much
- more important to ask why the sky is dark at night (Olber's paradox).
-
- An observation that you happen to speak english is the answer if you
- were to have posted this question in some area concerned with cultural
- anthropology, where debate would concern whether the !Kung think the
- sky is "blue", or even care.
-
- A philosopher might ponder the strong anthropic principle, or perhaps
- even the question of how we come to accept that another person sees
- the same thing we do when we both say it is "blue".
-
- A social worker would want to know why you are asking a question that
- discriminates against the visually impaired, who do not know what your
- question means and are frustrated by it. (Which, I suppose, begs the
- question of how it is that I was taught about Rayleigh scattering by
- a blind man. Life has its interesting twists.)
-
- And some people would be happy with the answer the Kibo created the
- universe, complete with your question and various answers, just a
- few nanoseconds ago, because...
