I'm referring to the necessity you've been arguing for, i.e., your contention that the universe is the way it is because it couldn't have been otherwise.
Remembe verse theories, are meant to explain the fine-tuning that we do observe.[/b]
“...i.e., your contention that the universe is the way it is because it couldn't have been otherwise. ...”
I never said that it was. Note the operative words “..for all we know, ...” in my original post.
“...Remember, the standard you have set for deeming fine-tuning reasonable ("...there is no... reason to believe in 'fine-tuning'." ) is nothing less than the observation of another universe with different constants ("short of actually finding another universe with different constants..." ). It follows, then, that neither is there reason to believe in necessity (i.e., "cosmological constants are what they are... due to merely the limits of what is possible." ) since we have never observed another universe with the exact same cosmological constants as our own. ...”
Correct. So? I never contradicted this.
I am NOT claiming and have NEVER claimed that "cosmological constants are what they are... due to merely the limits of what is possible."
again; note the operative words “..for all we know, ...” in my original post.
“...It renders your argument moot. ...”
But that is NOT the premise of my argument! Isn't it! And my argument doesn't depend on that premice.
again; note the operative words “..for all we know, ...” in my original post.
Reminder:
“...so, therefore, FOR ALL WE KNOW, it could be inevitable that cosmological constants are what they are ...”(my comment and my original post)
And none of this would make any difference to the conclusion that we cannot say anything about the probabilities of the physical constants being different to what they are and, therefore, by implication, we can say nothing about the probability of there being “fine-tuning”.
“..
BTW, fine-tuning doesn't imply 'design'.Fine-tuning is what physicists observe about the universe we know; a neutral distinction based on the precision of the cosmological constants and physical laws necessary for our universe to be as it is. Fine-tuning is a fact. ...”
I don't see how: doesn't the words “fine-tuning” clearly imply there is some “tuning”? There is absolutely no evidence to date of any kind of 'tuning' i.e. that the constants could be 'tuned'.
