Is the cosmos "fine-tuned"?

You are 100% wrong about that, buddy. It is a "scientific hypothesis," not a "scientific theory" because it is not falsifiable. See below
Thank you, but I have provided numerous references designed for scientists and scientific research concerning the nature of science (NOS) and scientific methods (to which I have contributed to), *post edited by RF staff*.

The multiverse hypothesis is a source of debate within the physics community
You can search my posts for this. I commented on it using actual physics literature years ago.

How utterly absurd. So physics doesn't explain why Newtonian mechanics completely fails? Why does it not explain "quanta"? What does explain mean according to your understanding of physics such that perhaps the most successful theory in the sciences of all time "doesn't explain anything"?
Umm. Straw man much? I said, Physics can't be used to explain things on the quantum level. I never said, "physics can't be used to explain anything." Newtonian mechanics aren't on a quantum or atomic level.

If you wanted to stay away from religion
I didn't. I wanted to (as I said in my reply) discuss how fine-tuning does or doesn't support design, as well as what it is. *post edited by RF staff*

And, you just avoided the entire argument. Do you just ignore the difference between Scientific Theory and Scientific Hypothesis? How can a "scientist" get away with that? There are very distinct, specific, and defined diferences.

Wild speculation. I agree. But if variation is in the cards, then, well, why not? My argument is as strong, or weak, considering how little we know about these things. We have not even managed to marry gravity to QM, for Thor's sake.

I follow, sorry for the misunderstanding. I think what you are doing is accepting the fine tuning "problem" and proposing a solution. In the sense of proposing a "hidden causal structure" that explains the meaningful coincidence. Your solution is similar to the multiverse solution in that it explains the apparent unlikeliness of the values by suggesting that it's not a question of the probability of the value being randomly selected, but of many many values being randomly selected and the universe settling on one. From an aesthetic standpoint or according to principles of parsimony, it would seem to me that the MWI solution may be simpler than that, since the problem in your version would be understanding how it is that the universe "stops" at a stable value.

Umm...contradiction in terms much? What the **** do you think quantum physics is? Using a magic 8-ball?
  1. Quantum mechanics (QM; also known as quantum physics, or quantum theory) is a fundamental branch of physics which deals with physical phenomena at nanoscopic scales, where the action is on the order of the Planck constant. This branch of Physics operates under a different set of laws than other branches of Physics.

No. I ignore all those who aren't scientists and rely on such simplistic distinctions that we real scientists cannot use for research but that so many such as yourself find definitive despite the disconnect between this pre-college and undergrad notion and actual scientific research>

There are very distinct, specific, and defined diferences.
Interesting, considering the we scientists don't actually make such distinctions and even in the philosophy of science and in some popular science literature (not to mention several decades of research in science education) deem your distinction to be not only misinformed, but lending credence to an understanding of the nature of science that is fundamentally skewed.

I would say the same about you, my friend. And it seems as though, through doing some research on my own, most scientists agree that there is a difference between a "scientific theory" and a "scientific hypothesis" as I do. And, btw, saying that you are a scientist and talkling down to everyone doesn't really act to convince anyone of your intelligence. Just a bit of friendly advice. Anyone can claim to be a scientist, so try not to rely on that too much.

I'm not your friend. You represent a position that I believe plagues the discourse between scientists and the public, which is misused by politicians, corporations, and even scientists. I have devoted years to attempts to counterbalance some small part of this. Your posts represent my failure and all those who, like me, which that the sciences were better understood.

And it seems as though, through doing some research on my own
What databases did you search?

Not really. My possible solution is to those who are actually concerened by that. However, it is an interesting mystery why the Universe had such a low entropy at the BB. Vastly lower, than the one needed to create life, apparently. Over-engineering, so to speak. And entropy is probably more important than the values of the constants. I can imagine many a stable boring Universe, but not an interesting one if we do not have exceptionally lower values of entropy at its "beginning".

Btw. What do you mean with MWI? Many Worlds was?

Eh Deidre's a cool and froody dudette, miscommunications happen. Can't we all just get along? :p
You are reasonable as always. I'm not, alas. I'm tired, sick (actually sick), and sick of having to defend positions that are granted by anybody whose field is relevant, etc. Is this unreasonable and childish of me? Yes. With more sleep I could grant more patience, despite the numerous posts that have misconstrued my intent, what I have sought to address, and the scientific literature. So it is probably best that I quit now, before I become really nasty.

I thought about this earlier in this thread and forgot. Penrose's book Cycles of Time on Conformal Cyclical Cosmology is interesting on this.

Multiple Worlds Interpretation of QM. The multiverse theory basically.

Yes. Although I admire Penrose a lot, I think it like to tend to the nutty side of things, sometimes :)

Oh ok. However, I do not think that they are the same thing.

Atheistically
If you change the constant Λ by .000,000,00,0000,00,000,000,000,000,000,000,000,000,000,000,000,000,001, there'd be no universe.

Which has nothing to do with life as we know it.


The fabric that holds the universe in formation was not made for life, it is simply nature.

You immediately equated fine-tuning with ID pseudo-science


Who did the fine tuning?

Why cannot life be a byproduct in a universe very hostle for life

I haven't belittled your thread or points, to be honest.
You reduced my entire thread to some thread "geared to argue in favor of ID"
We both know that these discussions are typically geared to argue in favor of ID. Which is fine, honestly. But, let's not pretend on a religious forum, in the religious debate subforum...that we're merely discussing the parameters of physics. ;)

It does. Were it different, no life would be possible.

Assuming that to be true, it doesn't negate or address the fine-tuned problem (or, for believers, fine-tuning argument).

Who did the fine tuning?
The guy who wasn't working on the plans for infinitely many universes: Bob Cratchit

our perception of probability is a funny thing isn't it?

It's interesting, that most atheists would accept the simplest mathematical sequence drifting across the galactic airwaves, as proof positive of alien intelligence (and hence humanity's insignificance).. (what other explanation could there possibly be?!)

while the multitude of staggeringly specific and finely tuned mathematical equations that permeate the universe, which make life possible, as observed in the universal constants, physics, DNA may be safely assumed to have accidentally blundered into existence for no particular reason...

it seems like these contradicting 'probabilities' are determined by their own implications rather than the math

Not "for no particular reason," as there is presumably a reason, in the sense of a cause. But that cause probably has nothing to do with life. Again, this is where the weak anthropic principle comes into play.

As others have pointed out, there are also ways to vary constants to make the universe more hospitable to life.
