Sorry guys. I am yet again staggered by the dogmatic responses I am receiving from some of you and the apparent ignorance of how current these ideas are within segments of the scientific community. Nevertheless your comments do merit a serious reply yet my current work load is making more than an occassional snatched post rather difficult. Please accept the incompletness of my replies as a reflection of my limited time and my limited communication skills, not as evidence of the weakness of the ideas themselves.
The constants of the Universe are not set to be ideal for life. Rather, life arose because the conditions of the Universe were favorable.
How do you know the constants are not set to be ideal for life? From the enormous range of possible values for these constants only a very restricted range of each makes life possible. This demands an explanation. Three spring to mind:
1) Despite the enormous odds, things just happend to work out that way. This is basically the Weak Antrhopic Principle. I find the WAP to be something of a cop out.
2) This is only one of many, many universes, most of which cannot and do not contain life. We have some speculative mathematical expositions to support this notion, but no real evidence.
3) Against this backdrop the teleological explanation is surely one worth considering.
There's no probability involved - life arose in the environment where conditions were favorable because conditions were favorable.
This is an unsatisfactory explanation. Science seeks to provide explanations and saying 'that's just the way it is' is little better than saying 'God did it'. The favourable conditions of the environment - the remarkable favourable conditions of the environment - require an explanation. This was first pointed out by Henderson in 1913(?) in his work 'The Fitness of the Environment'. It has been amplified by others since.
Do you really think it is scientific to simply ignore this fact? Are you concerned that it is an area that would not lend itself to scientific investigation? I am at loss to understand your resistance.
The argument that the favorability of conditions in our Universe, or on our planet, or anything else, is based entirely on personal incredulity.
Please don't talk nonsense. Are you actually questioning the fine tuning of the fundamental constants? I am not, offhand, aware of any cosmologists or physicists who doubt this fine tuning. Some may favour explanations 1) or 2) above, but none base their belief in fine tuning upon a personal incredulity.
And do please note - I have no idea which of the three explanations is the correct one. I have a prejudice against the weakness of the WAP, but do not entirely rule it out. I am completely open minded on the issue,therefore patronising remarks such as those you employ in your last paragraph entirely miss the mark. Let's try and stay focused on the issues rather than engaging in a flame war.
