>>>David Bowman: ... It is clear to anyone who does know what entropy is,
and who knows what kinds of processes that happen to occur in the Sun that
the entropy of the Sun *is decreasing* with time as Richard reports.
DNAunion: I will take that as a favorable remark towards my understanding of
thermodynamics (whether you meant it as such or not). Why? Because I was
correct when I said ...
>>>DNAunion: [Whether or not the entropy of the sun is decreasing or not]
Seems like an irrelevant point to me. Anyway, there would be nothing wrong
with the sun's entropy decreasing because the sun increases the entropy of
the surroundings in compensation.
DNAunion: I did not give details (as the topic was irrlevant to life, as I
pointed out to Richard). You did give details:
>>>David Bowman: What *is* increasing in entropy is a) the electromagnetic
field which is carrying (and whose elementary excitations include) the
outbound photons of solar radiation streaming away from the Sun, and b) the
neutrino field whose excitations include the outbound neutrinos which result
as a byproduct of the production of the nuclear neutrons (in the He-4
product) from the reactant protons.
DNAunion: My very short summarization covers this: we are both saying that
the Sun is increasing the entropy of its surroundings.
