I haven't been using arguments to verify God. I have been supporting ID which does not try to prove God and is only concerned with signs of ID in life. If you take an individual sign such as say how living things have inbuilt mechanisms that allow them to produce variation that is directed at specific outcomes rather than any outcome with blind chance evolution then you only have to prove that and not God.Well, if it's a bad idea for me to use something that is impossible to verify, does that mean you're stop going to use arguments for God that are impossible to verify - namely, all of them?
As one of the articles you posted says that we cannot verify a multiverse and that it is only used by scientists because there is no better idea at the moment.And there is actually some pretty good reasons for accepting the multiverse idea as correct...
What Is (And Isn't) Scientific About The Multiverse
Multiverse: have astronomers found evidence of parallel universes?
That's the idea of the multiverse. As you can see, it's based on two independent, well-established, and widely-accepted aspects of theoretical physics: the quantum nature of everything and the properties of cosmic inflation. There's no known way to measure it, just as there's no way to measure the unobservable part of our Universe. But the two theories that underlie it, inflation and quantum physics, have been demonstrated to be valid.
So what? That's not a whole lot, is it? There are plenty of theoretical consequences that are inevitable, but that we cannot know about for certain because we can't test them. The multiverse is one in a long line of those. It's not particularly a useful realization, just an interesting prediction that falls out of these theories.
So why do so many theoretical physicists write papers about the multiverse? About parallel Universes and their connection to our own through this multiverse? Why do they claim that the multiverse is connected to the string landscape, the cosmological constant, and even to the fact that our Universe is finely-tuned for life?
Because even though it's obviously a bad idea, they don't have any better ones.
As it mentions above there are many interesting theoretical ideas that fall out of quantum physics just like a hologram universe or time travel but we don't say they are all verified. As mentioned one of the big reasons scientists like the multiverse idea is that it counters the fine tuning argument but that is not a reason to say that it is true either. Ideas are just hypothesis and it seems the ones associated with quantum physics can have more speculation. But it also reduces the predictability that is required for scientific verification.
One of the founders of Inflation theory Paul Stienhardt says that the cosmic inflation theory is wrong because an inevitable consequence is that it leads to a multiverse. But a multiverse negates the purpose of why inflation theory was developed to address the need for our universe to be smooth and flat. A multiverse negates all this as it introduces many universes that could also consist of any number of conditions that are not smooth and flat. As Stienhardt says
As the original theory has developed, cracks have appeared in its logical foundations.
Highly improbable conditions are required to start inflation. Worse, inflation goes on eternally, producing infinitely many outcomes, so the theory makes no firm observational predictions.

Its raison d’être is to fill a gap in the original big bang theory.
http://physics.princeton.edu/~steinh/0411036.pdf
So it was partly formulated to address problems of the big bang theory which it doesn't and now is being used to address the problem of fine tuning.
But that is what some want to do with ideas which stem from quantum physics. If we are going to use ideas like a multiverse or time travel then why not the God hypothesis as we also have indirect evidence for this such as the fine tuning argument which a another unverified idea in a multiverse tried to negate.And you would never use an idea that can't be directly verified, would you?
Except ID does not set out to verify God. It is only concerned with signs of ID in life and existence.Except that ID can never tell us anything scientific about this alleged designer, can it? Seems like a very large flaw in the idea!
For the fine tuned universe for intelligent life that is all we need to show and verify. Both of these have been verified by the scienceWell, you seem to be saying that life can only take one form - the kind of life that we see, which requires a universe with certain conditions. You haven't shown this to be true,
Yes that is one reason the multiverse idea is being used because it counters the fine tuning argument. But the point here is that you are using an idea that has not been scientifically verified. If anyone who was trying to support ID used this logic they would be shot down.but even if we accept it, the multiverse theory says it doesn't matter, because conditions for that life are going to arise in one universe, perhaps even more.
I have understood the idea from the start, it is a well known idea to counter the fine tuning argument and I agree if it was verified it would counter the fine tuning argument. But there were 2 issues I had with this. First when you introduced the pothole example it was not about a pothole multiverse. The example was just assuming the water woke up in the right hole and there were no other holes. Second a pothole multiverse or cosmic multiverse has not been verified so is unscientific. All we have is our universe which has been shown to have a number of specific physical conditions that has allowed intelligent life and unlike a multiverse we can measure this directly to verify things. Until we find intelligent life within our universe or in another universe ours is the only one which makes us very special.Imagine a road with many potholes. An infinite number of potholes, actually. Each pothole is a different size and shape. Since there are an infinite number of potholes, any conceivable pothole must exist somewhere on this road. Each pothole is like a universe. Now, imagine that we have some water that, for some reason, is locked into a particular shape. Can this particular shape-locked water find a hole in the road the exact size and shape to fit it perfectly?
The answer is yes, because every single possible hole exists somewhere on this road.
Likewise, if every possible universe exists, then we must find there there is a universe with the conditions required to support life.
This is not a difficult idea to understand. If you are still having trouble, I'd suggest that you do not have the skills to grasp the ideas required for this discussion.
You don't understand statistics, do you?
The problem is the type of odds we are talking about is way more than the population of the earth. In fact it is way more than the population of a million earths.It doesn't matter how many possible combinations there are. The chance of winning ios still greater than zero, and it is still possible to win. It is not IMPOSSIBLE. And if you get every single possible ticket, you are guaranteed to have the winning ticket.
Say the lottery works like this. There are a trillion tickets in a barrel, each one numbers with a number from one to a trillion. Each tickets is half of a matching pair, the other half of each ticket being sold to someone who has entered the lottery. Open the barrell, draw a ticket, and whoever has the other half of the ticket wins the prize. So if the number 1,634,297 is drawn, and I happen to be holding the half ticket that has the number 1,634,297, then I win the prize.
Yes but you are hedging the odds. If there is only one universe that's holding the lottery that doesn't work with the fine tuning argument because only one ticket number can be sold and you have to have it out of 1 trillion tickets. But not only one ticket number but around 150 ticket numbers correct and you would have to win the lottery around 23 times in a row. The odds for just the cosmological constant at 1 in 10 to the power of 120 is like piling coins on the US to the moon and then picking the one different coin with one pick. For all the constants to line up as this article mentions it would be 1 in 10 to the power of 234.The odds of any particular ticket being drawn is going to be a one-in-a-trillion chance. And yet SOME ticket has to be drawn. And if I have purchased every single ticket, then I know that whatever ticket is drawn, the other half of that ticket is going to be in my hand.
For them all to be what they are by random chance is the very unlikely probability of 1 part in 10 to the power of 234. You certainly would not bet on these odds.
How Did We Wind Up in Such an Unlikely Universe?
As Lee Smolin states who is a atheist
Lee Smolin, The life of the Cosmos, page 53:
Perhaps before going further we should ask just how probable is it that a universe created by randomly choosing the parameters will contain stars. Given what we have already said, it is simple to estimate this probability. For those readers who are interested, the arithmetic is in the notes. The answer, in round numbers, comes to about one chance in 10^229. To illustrate how truly ridiculous this number is, we might note that the part of the universe we can see from earth contains about 10^22 stars which together contain about 10^80 protons and neutrons. These numbers are gigantic, but they are infinitesimal compared to 10^229. In my opinion, a probability this tiny is not something we can let go unexplained. Luck will certainly not do here; we need some rational explanation of how something this unlikely turned out to be the case.
How Did We Wind Up in Such an Unlikely Universe?
So once again luck as in trying to explain things through lottery examples cannot account for the level of improbable odds.
Fair enoughYou say you understand the puddle example, but I don't think you do.
So what if there was only one puddle and the conditions were not conducive for intelligent life. There would be no intelligent life.You see, the point of the puddle example is that life will adapt to fit the conditions that already exist,
Life did have to be a certain way, it has to be intelligent life because that is what the fine tuning argument is about. The conditions do have to be a certain way because only certain conditions will allow intelligent life.yet you are still going on about the idea that life had to be a certain way and the conditions needed to be set prior to life.
If we don't appeal to a multiverse (which the puddle example doesn't) the conditions need to be set at specific physical constants for intelligent life to come about. If they were slightly different then there would be no intelligent life. Considering that those constants (around 150 in total) could have been set at any level if they came about by random chance then that is an impressive feat. AS shown above impossible odds in the context of any lottery example.
The puddle example does not use a multiverse to hedge the odds. And a multiverse is unscientific as it has not and can never be verified. But only if a multiverse was scientifically verified would it counter a fine tuned universe for intelligent life.And you are again forgetting about the multiverse theory. If every single possible universe exists, then it's guaranteed that there would be a universe with the conditions we see in this one.
Then why do scientist use the multiverse example to counter the fine tuning argument for intelligent life. I would say because one of the universes (ours) has intelligent life. So the multiverse then makes our fine tuned universe not so special as there would be all other varying conditions from a fine tuned one to a totally non-fined tuned one and everything in between.That is the strangest reasoning I've ever heard. If every single possible universe exists, it does NOT mean one of them was fine tuned.
