Those who do the studies claim their simulations are fairly accurate.
After all, they tweak the universal constants only slightly. For
illustration, the simulation produces variety of matter when say
constant A is set to 46.2743827 (ours) but results in uniform plasma
when set to 46.2743820. How can the simulation be accurate and then
inaccurate with only a minor change in a constant? It is possible, but
a little bit far fetched.

Anyhow, you would have to take it up with the simulation runners. Maybe
their simulations have a flaw, but nobody has apparently found it yet.
Saying it "might be wrong" without identifying a specific flaw is not
very useful.

Not all simulations are equal. Some of the people doing string
theory had known constants fall out of their theory. I have this book
on cosmology and I find it enlightening to think about blackholes. It
is talking about the big bang but it applies to blackholes. In both
places one will find a "sea of quarks".

like I said not all simulations are equal. Quibbling about the 13 ( or
7) decimal place is specious, because we do not KNOW that precision
about various constants.


No need to quibble about the 7th or 13th decimal place in many cases.
Lower the mass of the neutron by 0.2 percent and the mass difference
between protons and neutrons will reverse.

What happens then? Protons will decay into neutrons because it would be
energetically possible. With no more charge in the nucleus, atoms would
fly apart because there wouldn't be any force to hold electrons in orbit.
The electrons would annihilate with the positrons emitted by the decay of
the protons, producing radiation. The whole universe would become a
"neutron world" consisting of bare nuclei of neutrons swimming in a sea
of radiation.

Sad.

Thats right. degenration into a sea of quarks. space would melt. the
universe would get HOT. HOTTER. HOTTEST. the universe would evaporate.

The folks I know that were modeling universes, noted that MOST are not
compatible with life or even matter.

But that's only the universes with the constants that this universe has.
What about the universes with structures and constants that we can't even
imagine? What about the existence of life as we can't imagine it?

And if you reply that such questions are too speculative, then I'll just
assert that considering alternate values for the constants of this universe
is too speculative. We have no reason to assume the constants can even have
another value, or that they're not all tied together in such a way that
changing one changes them all, and that the resulting universes are all
valid for the existence of life.
