That's a fascinating view that I haven't heard proposed before.
You're proposing that they DO NOT change speed, as commonly explained.
The separated light would presumably lose mass, because it is now only
*part* of the original.

That's a more parsimonious explanation -- that they have more or less
energy, not speed.  But I think, in fact, that this is where there is
a tradeoff in the energy vs. information/data equation of the
universe.  Information (or data) is the opposite side of energy.
Color is data, more than illumination (at least in a rainbow, where it
is questionable whether it would illuminate anything).

I think you answered part of my question, which was partly didactic to
force science to get more rigor in its explanation.  I think I will
have to content myself with this because I know that rainbows and the
sky being blue will NEVER be explainable by science.
