A WEAK CASE FOR A WEAKLESS UNIVERSE

You can check out the original article here at
"A
Universe Without Weak Interactions" and the later paper
pointing out the problems at
"Problems
with a Weakless Universe" .

Considering how I stressed how much varying the weak
force's strength would mess up complex life arising, I
didn't want you confused if you saw an article about the
"Weakless Universe", like [URL=http://www.scientificamerican.com/article/looking-for
-life-in-the-multiverse/] this one in SCIENTIFIC
AMERICAN .
The "Weakless Universe" wouldn't allow our type of
life–which is, after all the only type of life we know
(precluding oxygen, both what we breathe and a major part
of DNA, and water,which is hydrogen-plus-oxgen…) but
perhaps not more exotic proposed forms of life, like
methane life.
And yes, the "weakless universe" works if you cherry-pick
another value to try to compensate what you just did. And
that's kosher. Varying the strength of the weak force is
cherry-picking too, and there's no rule against TWO such
adjustments…
But it DOES point out how you have to have the constants of
nature in a very narrow range for even a marginal chance
for life. The Weakless Universe is not a "generic" universe
in that sense.
Is ours? Well…
Stay tuned.
