The proponent of the theory still does not answer the three questions I have provided. Maybe he's avoiding them instead of conceding that he's wrong?
Who was this directed at?Based on speculation? Do you even know what you're talking about? A theory is the highest status any hypothesis in science could ever obtain. A scientific theory has overwhelming evidence to support it. Perhaps no one bothered to tell you what a "scientific theory" is
It carries weight when I am saying it is not a no brainer. If I can produce physicists - including ones who publish regularly in their field - for whom the issue seems to warrent an explanation, then this is evidence of my assertion. I do no think either you or I are actually well enough trained to decide whether those pro or con are correct. That is a separate issue. I am not making the case that the Strong Anthropic principle is correct.Argument from Authority carries weight. Albeit- little weight.
Never asserted anything remotely like this.If there are scientists that are practicing theists, one cannot say that Scientists believe that God is real. (Anthropic Principle aside).
Earth, as a planet in the universe, is not a part of the Anthropic principle per se. That there can be an earth or any planet that supports life is the issue. But, again, please note. I was asserting that the issue is not resolved and people with good brains feel that the apparant fine-tuning warrents explanation.However, what you are citing is different from what haereticum135 is proposing.
Secondly, your assumption is that Earth holds a special place. It really doesn't.
I don't think you understand the Anthropic Principle because these examples are off target.Perhaps the conditions here are more favorable to life than on other planets. Well, then it's a good thing we up and decided to exist here, huh?
It seems reasonable to say that Earth is favorable. After-all, we're here.
What you did NOT show is that the Earth has many specific traits that make life ONLY possible here, that life could NOT develop in similar conditions and adapt to its environment, nor does that demonstrate any validity to haereticum135's claims anyway.
Deep oceanic Worms living at vents probably find their environment perfectly designed for them.
Then you might want to consider using the quote function, otherwise people will think you are responding to the posts just above yours. You might also consider consolidating your posts."Who was this directed at?"
This was directed at the proponent of the biocentric fairytale.
what issue warrants an explanation?It carries weight when I am saying it is not a no brainer. If I can produce physicists - including ones who publish regularly in their field - for whom the issue seems to warrent an explanation, then this is evidence of my assertion.
It was not a response to something you asserted. It was an example I provided to demonstrate the weakness of Argument from Authority.Never asserted anything remotely like this.
How is it not resolved?I was asserting that the issue is not resolved and people with good brains feel that the apparant fine-tuning warrents explanation.
It's not a no brainer. there are a good number of physicists who find the conditions odd. And the issue is not simply whether DNA based life could form, but any life at all would have been inconceivable if just a few fine differences were there in certain constants. You and I can go back and forth on this, but I assure that there are a good number of scientists who are bothered by this. A number of them consider the conditions such that it points to a multiverse.The odds of finding Earthlike conditions are not really low so much as that life adapted to Earth like conditions. Kinda a no-brainer, that one.
that the universe even allows the possibility of life, given how even minute shifts in constants make not simply DNA based life impossible, but any kind of life we consider possible.what issue warrants an explanation?
OK, it came after what I wrote, so I thought it related to me.It was not a response to something you asserted. It was an example I provided to demonstrate the weakness of Argument from Authority.
There is not consensus around the various anthropic principles in the physics community.How is it not resolved?
OK. I can see how you took what I meant. But the anthropic principles deals with the possibility that life friendly conditions of any kind could form anywhere in a given universe or in this universe. The scientists who feel that a multiverse is indicated are not focusing only on earth, but on the universe as a whole and why the constants have ended up falling in a very tight range where any life at all is possible.Doreen-- My examples are based solely on yours.
YOU said that you could produce cites for scientists claiming that Multiverse helps explain Why the Earth is "Perfect" for Life.
I am not claiming that they are fine-tuned. I am claiming that scientists 1) think they fall within a remarkably small range that could support any life at all and 2) that a subset of these scientists think it is odd enough to demand some sort of explanation. Some of these latter think a multiverse explanation helps to explain why the conditions are just so.Whether or not Life has adapted well to the conditions or your claim that the conditions are fine tuned to life.
My links in the two posts I had links show that the issue of the strong anthropic principle is and has been under discussion in the physics community and that some link a solution to the multiverse explanation.Your links only support a multi-verse explanation toward the Hubble Volume. Or the Universe itself, observed and unobservable.
Where do you get this idea at all?that the universe even allows the possibility of life, given how even minute shifts in constants make not simply DNA based life impossible, but any kind of life we consider possible.
Just because they do not focus on Earth does not support the idea that Earth has a very tight band in which life can develop. I can rattle of dozens of possible life forms in very extreme environments- Ala Carl Sagan style.OK. I can see how you took what I meant. But the anthropic principles deals with the possibility that life friendly conditions of any kind could form anywhere in a given universe or in this universe. The scientists who feel that a multiverse is indicated are not focusing only on earth, but on the universe as a whole and why the constants have ended up falling in a very tight range where any life at all is possible.
Again- Who thinks that?I am not claiming that they are fine-tuned. I am claiming that scientists 1) think they fall within a remarkably small range that could support any life at all
From your links, I saw no scientists claiming ANY of what you just said.and 2) that a subset of these scientists think it is odd enough to demand some sort of explanation. Some of these latter think a multiverse explanation helps to explain why the conditions are just so.
My assertion is that it is not a no brainer because people with hefty brains are working to deal with the issue and were not satisfied with an explanation such as yours. There are physicists who make a similar argument to your short dismissal much earlier in this thread. You are these physicists may be correct. However given that enough very intelligent brains out there take the other side or at least put in a great deal of effort explaining there differences with the various anthropic principles, the issue is not a no brainer.
It seems odd that the topic diverged to arguing whether or not the universe was "fine-tuned"
