Dear Ken!
Thank you for your kind comments!
I did actually mean 'anthropmorphic' (man-shaped) when was initially talking about the physical laws. The fact that we call them 'Laws' or 'Laws of Nature'. We think of these as rules that things must obey. 'Obeying rules' is a very human-centric perspective. I did not really come back to it because I used it as a means to discuss the idea that even a Creator would be able to create in an unconstrained manner. My mere mentioning of a Creator seems to have ruffled some feathers, but the point was that there are constraints that cannot be broken. 2 3 is not ever going to be 10. Everything would break. And that is meaningful.
I myself don't believe that the constants change. Pi doesn't. What really is important is that we really do not understand why some constants have the values they do. Until we understand that, we cannot know that the values cannot change, and we cannot know whether other universes might have constants with other values. That was really what I was going for.
But the fact that this universe is nicely tuned for life, the anthropic principle (of or relating to humans), is interesting. This is especially true if there are reasons why the constants have the values they do. Then, it seems that things will be difficult to reconcile.
Thank you again!
Kevin
