What can be pushed up, can be pushed down.Again, this just shifts the Fine Tuning up a level. If the constants are somehow set-in-stone, why are they set at the particular values that allow for a life-permitting universe? That would just be a stronger version of E:
Why are we only concerned with dimensionless parameters? Why not others? And for that matter, why are we only trying to account for intelligent life? Why not civilizations that send radio waves? Or just outright humans? Or pigs for that matter?
Are the questions we're asking even the right ones?
If you're seriously going to say "this just pushes the problem up a level", then it seems your problem is actually manufactured in the first place--you're asking about why universal constants are such that they make, coincidentally, the very things we care about existing.
Wait a second... are you sure you have a proper burden here? You don't want to add in the possibility that no parameters can vary, because "it doesn't follow that it can be 0"? No... I refuse this burden. Feel free to toss in a low probability for the Jk that represents the ontological necessity option, but hear this...There may not be a consensus about the number of constants that have to have precise values, but it doesn't follow that the number could be 0.
I'm being nice to even grant you the notion to allow H into this in the first place. I mean, look at what you're doing. Consider H', alone. And consider it very, very seriously, in light of your intuitions. The probability that intelligent life actually wound up, as a result of the universe being the way it is, is astronomically low (pun intended). Now pause to consider the implications here.
We're talking about us--200 pound slabs of meaty apes, who can think. 200 pound apes, mind you, who have only built civilization about 10K years ago, running around on a huge planet that has been filled with all sorts of life, doing their own thing, for billions of years. Just a measly animal, with a tendency to develop bigger brains, who happened upon tools, and wound up where we are--who only recently discovered 95% of the universe that we didn't know existed before. And the odds that such a tiny minuscule consciousness arose... astronomically low.
And you dare consider an H hypothesis, which has it that a transcendent entity, built on mechanics we've never heard of, so vast he can create universes, with intent, exists? If the odds of a mere 200 pound ape is low, well... the odds against that H thing have got to be insane.
We're throwing H into the equation like it's nothing... and you don't even want to warrant consideration for this Jk?
The proper burden for excluding Jk isn't that I have to prove the choice can be 0... it's that we can rule it out as a viable alternative.
Alright. Here's the way it works. Let's say that only 1 parameter needs a value, and it can be in a fairly large range. 100 to 200 units. It's just 1 parameter, mind you.It could be there's a baseline of 20 or so constants that have to have precise values to allow for life and speculation about another couple dozen. The source I cite states:
Now, what are the chances that this 1 parameter will fall within the range 100 to 200? 50%? 25%? 900 to 1 against? 1 billion to 1 against? 0?
You simply don't know, do you? That's because telling me a range that the parameter lies in, tells me nothing about the probability the parameter will lie in that range. And how could it?
Seriously? We don't have to ignore him. Qualitatively, he's right. Key enzymes do need to come together. Just find a biochemist.Then ignore him and focus on the other six or seven. Linde and Hawking are hardly Christian apologists.
What's interesting, though, is that he was brought up at all... and that there was a comparison made to Drake equation, with the implication that that was rational.
It'd be a good idea, then, to get professional physicists' opinions as to the fine tuning argument for God, would it not?None of us are professional phyiscists, so a lot of this is going to be an appeal to authority.
You're missing the point. You're using Penrose's number without knowing what it means. You're plugging it into an equation that's supposed to compute an outcome from all collectively exhaustive outcomes. This is not about questioning Penrose's credibility--it's about knowing what you're using and how it fits into your equation.I don't know what model Penrose used and I probably wouldn't understand it. With all the awards won and discoveries made, attacking Penrose's credibility on this is probably not going to work.
If they have set values, why would you need a God to set them?Again, it doens't matter if the values of the constants are set or come about by chance, because the evidence is they have to have precise values either way for life to even have a chance. E1 or E2 both confirm H (E2 much better).
Or that life is just natural. You can't just cheat. The probability that God exists in the first place should be considered, and God is a much more unlikely thing to "just be" than we are.It would be extremely rational to believe something that favors life set the constants at the precise values needed for life, and that is the point of this whole thread.
And this suggests what part of the problem is. You're answers based. You want a view that will explain things. I'm not like you. I'm doubt based. I want to work really hard to get my explanations, and I want them based on my observations, because I know the power of humans to fool themselves.You have not presented a model that would make Pr(E/~H) > Pr(E/H).
Put it this way. You are willing to use argument for authority for physics. Why? Because physics is damned hard. You can't do physics anywhere near the capacity as an expert in the field. But philosophy? Theology? No problem! And don't get me started on mathematics.
Truth isn't easy to get to. It's mightily convenient to not claim expertise in a field where, if you put your money where your mouth is, you'd blow up a rocket rather than manage to get it to land on Mars. But for some reason--these much bigger questions--much grander ponderings... you can estimate on the back of a napkin, no problem! But it's only because you're not going to blow a rocket up when you're wrong. You don't get slapped in the face, or kill billions of people, by... ooops... concluding god exists when he doesn't.
I want you to deconvert from this temptation of easy answers to difficult questions. It's nowhere near as easy, and you're not even close to a proper napkin estimate.
Well, for example, that either God created the universe, or the planets arose with odds of 10123 per Penrose's napkin... which, by the way, was computed based on some unknown model, based on the Standard Model--which we know isn't complete anyway.What false dichotomy?
Of course, none of your actual numbers in the other threads were real estimates from these people anyway.
