I know some fine-tuning conditions which must be true in order for our universe, as we know it, to exist, for stars to shine and for the life to develop.
For example,
* CP violation (otherwise no matter because everything would annihilate)
* Diproton (p+p) must be unstable (otherwise stars will burn out too quickly)
* neutron should be unstable (important in the early universe)
* dark matter exists (otherwise Jeans mass is too big in early universe - galaxies do not form)
* there should be no stable particles containing 5 and 8 hardrons (otherwise stars will burn out too quickly)
* etc, etc, etc
My question is if there are any attemptx to create - not a full list of such conditions of course, but at least put in that list all we know - from astronomy, chemistry, star evolution, biochemistry etc.
And them map these conditions to 30 parameters of the standard model + 2 parameters beyond standard model (percentages of DM and DE)
I know the 'island of stability' is very small. But what exactly is it's size?
P.S. More difficult question - are there any OTHER islands of stability which allow for life to develop (even chemistry might be completely different?)
