2) I'm not sure I ever met a physicist who, after thinking about it, doesn't agree it is a problem. Those who are cosmologists, astro, or particle physicists pretty much already know it is a problem A, say, solid state physicist--who might not spend time thinking about cosmology might not immediately agree--but in all cases I have experienced will agree after a discussion. So I literally do not personally know any physicist who says that it is not a problem.
3) You are mistaking condescension with insults. If anyone asks me a question in good faith, no matter how dumb, I will try to give a polite answer. That's the teacher in me. But if someone acts like a jackass then I can dish it back out. I have a lot of experience. I'm treated on here no different than I was treated on Pharyngula and I managed to survive there. Did I miss your similar moral outrage at the names I was called?
And I disagree that it is manifestly true that "So if you aren't being understood, the fault lies in your failure to explain yourself clearly" No, sometimes people just don't get it, willfully or otherwise.

A couple of dumb but sincere questions for Heddle.
In 1) if the answer is not luck, what is it?
2) sounds like an argument from authority by association. Why should I care for such a double fallacy?
You've repeatedly asserted that you are a scientist and that fine-tuning is a problem. You seem to poo-poo all discussion about possible solutions, which is at odds with what real scientists actually do. If you are here as a 'teacher', why are you making such a fuck up of it?
1) We don't know the answer. That is why it is a problem. Luck is one of the possible answers but the least satisfying for physicists. If there was (or if there is shown to be) no fine tuning then "the constants are just what they are" would be an OK answer for most of us, and how the constants got those values would be a much less intriguing question. It some sense instead of "fine-tuning" the problem could also be called "the unsatisfying appearance of luck problem" for cosmology.
2) What sounds like an argument by authority? Is the fact that what I have written, which boils down to
i) fine tuning refers to the observation that the universe's ability to synthesize heavy elements appears to be on a "razor's edge" and
ii) physicists believe fine-tuning is a problem
really a logical fallacy (a double one even!) when arguing against the counter position presented here, which I would characterize as
i) no it is not a problem for physics, and
ii) the solution is either a) because who cares? The constants are what they are, or b) some variation of a puddle argument or c) maybe there could be life without heavy elements.
You don't win an argument simply by
claiming a logical fallacy. Even a double one. That is the cheapest of self-satisfying tactics.
How is it that I poo-poo not just some but
all discussion about possible solutions? It seems to me that I have repeatedly discussed and introduced some of possible solutions. I have:
* Agreed that luck is a
possible solution but the least satisfying of all. I am confident most physicists agree.
* Stated and weakly endorsed he the multiverse solutions without poo-poo-ing them. I said way back that they are presently the best fit, in that they generally predict that the constants will appear as a random draw which, combined with an effective infinity of universes, results in a straightforward anthropic explanation of our "luck." To me that is the most satisfying physics solution. It suffers, at least at the moment, from a serious lack of testability. Is pointing that out "poo-poo-ing?"
* After someone brought it up, I commented fairly (I think) on blackhole cosmic natural selection. Is the fact that I pointed out it suffers from some vagueness "poo-poo-ing" it? Is your definition of "poo-poo-ing" equivalent to "failed to offer a ringing endorsement?"
* Acknowledged that demonstrating that the fine-tuning is an illusion is in principle a very good approach--perhaps even the best approach. It suffers no real obstacles in principle except that done properly it is an extremely difficult approach.
The most you can say is I poo-pooed Victor Stenger's approach to this. We could go through his book in detail but for now I provided only the circumstantial evidence that it appears only Victor Stenger and non-scientists (or perhaps out-of-field) scientists who read his book think that he has succeeded. The book was not peer-reviewed--nor is it a popularized companion to peer-reviewed research. Cosmologists continue to treat the fine tuning as a problem and make no reference in the professional literature to the problem having been solved by Stenger.
I
have arguably poo-pooed solutions of the form "well maybe there could be life with only hydrogen and helium." I stand by that. If that's what you are referring to then mea culpa.
And I am not
here as a teacher even though I happen to be a teacher/professor. Perhaps I am making a fuck-up of it. But it certainly is easy for you to accuse me of logical fallacies and pedagogical impotency without saying anything substantive.
