Physicists and cosmologists think that tiny changes in a number of fundamental physical constants (like the charge of the electron, etc.) would have resulted a universe in which life of any kind would be impossible.

Life of any kind? I doubt that physicists would say that. Life as far as we are aware of it existing? Sure. Life of any kind? Doubtful. We are still finding life on earth where experts didn't think life was possible - near underwater volcano vents for example...

Read my posts. I said that minor changes in some fundamental qualities would lead to a universe which would never expand, or to one which is all energy--not even any stars, let alone planets, organic matter, etc. How do you get life if there's nothing but light out there?
This is not my theory, or that of creationists. It's a problem physicists and cosmologists have thought about a great deal. They refer to the "anthropic principle," meaning that the universe just happens to be set up to allow us to appear, and to understand it.

I'm a little late to this conversation, but you may be interested in the book 'Life As We Do Not Know It', by Peter Ward (biologist at U of Wash).
