There is nothing to suggest any gawdly "finely tuned" constant.Good
So we are leaving the presup. argument of "fine tuning" and heading back to the more respectable experiential argument of spiritualism in inexplicable phenomenon?
The fact that science can't deny or avoid the problems of a precisely and finely-tuned universe is not an "argument." We can have different opinions but the constants are there and the evidence is empirical. The question of why the universe is finely tuned is beyond the ability of science to answer at this time, and probably ever. All other options require faith.
The only way I can even see you making this fine tune argument work is if the numbers you are given are the exact factors you are multiplying by and not deviation for some specific digit in the constant.
However, if that was the case, then this whole "Fine tune" argument is junk--multiplication by those factors is causing forces to vanish in those models. Gravitational constant multiple by 2x10^-9---You pretty much made a force vanish by algebra--not change a digit at 8th or 9th place.
The scope of the factor is too large/microscopic to talk about "fine tuning"n or precision. The range of possible values it still great between what we measure and what is being assumed for gravitational collapse.
I did not pick that up and until I read that Rees quote. He is not suggesting that the 5 th digit of the gravitational constant be changed and these things happen--He is saying that if the gravitational constant was about a million times weaker or stronger this problem would be present.
A factor of 1 million is not a precision measurement--and the concept that a difference of a factor of a million suggests high precision fine tuning is a bit of a reach to me.
If you want to talk fine tuning--keep the factor within the statitistical margin of error such as 5%(i.e factors of 1.05 or .95). If we are talking about values outside of the statistical model of error, then we are not talking about acceptable forms of precision which "fine tuning" suggests!
It seems you are still talking about things we measure and how accurate we are at measuring them. This simply doesn't matter to the physical constant which is empirical regardless of our ability to measure. The constant exists in constant state whether we can accurately measure it or not. Without this finely-tuned constant, gravity doesn't function. It does not matter what we are able to measure.
Are you still in a stupor? Do you have anything yet regarding your inability to present evidence for either one or more gawds or any evidence to connect those gawds to such "fine tuning".
