So? My backyard is lacking in objects to fill it. So what??
What do you mean, so? If youre going to say the UNIVERSE is fine-tuned for life, then youd better be able to show that there is an abundance of life in this UNIVERSE you say is fine-tuned to contain it. Pointing out that theres life on some parts of the earth doesnt do that. What is it that youre not getting here?
Or put another way: If the universe is fine-tuned for life, why is life so rare?
Demonstrate the existence? You exist, and I exist, right?
Yeah, we live on EARTH. Try living on Mars and see what happens to you.
And the Penrose number was calculated considering everything that is within the observable universe. So everything that is beyond planet earth is irrelevant if the low probability remains the same despite it.
Theres a major contradiction in your argument. How can you say that he made his calculations considering everything that is within the observable universe while at the same time dismissing the entire universe and focusing only on the life present on earth? That makes no sense. Everything beyond planet earth is NOT irrelevant when were talking about the UNIVERSE.
And again, Penrose couldnt possibly have taken into account the number of possible other universes that could have formed with different physical properties that could still lead to some form of life because nobody knows what that probability would be. And again, we have no other universe to compare this one to.
The low entropy conditions must have been an initial condition of the big bang itself. The precision that is needed is HIGHLY less probable than the contrary, so the only way these cosmological constants wouldnt exist would be if the designer involved wouldnt have allowed it to be the way it is.
Apparently the total entropy of the universe at the start of the big bang was almost zero but would have had more order than the universe we now observe because it was much more compact than it is now. The entropy of a closed system can never decrease but some parts can decrease at the expense of other parts increasing in entropy. Is that what youre referring to? Im not really sure what youre saying here and why entropy has made its way into the conversation. What precision is needed?
If you assume a designer is involved, that you can assume basically anything you want. Magic is a good explanation for just about anything, I suppose, even though it really tells us nothing. Im quite happy science doesnt work that way.
Um, okay so youre telling me that calculations about the UNIVERSE are only applicable to EARTH? Are you serious? How is the UNIVERSE irrelevant when were talking about the UNIVERSE?I dont need to look any further than the life on THIS earth. The Penrose calculation applies to this life and this earth.
So are you denying the fact that in order for life to be permitted, certain conditions has to be met?
Im saying that in order for the life we are currently aware of to exist, certain conditions might need to be met, but that doesnt account for other types of life that could occur under different conditions. We have no idea what those could be, but we cant really rule anything out. . I.e., These probabilities only apply to life as we know it and your claim assumes that life in its present form is a given, which we definitely dont know.
No scientist disagrees with the fact that our universe had to meet certain specified conditions in order for life to be permissible, and by specified, I mean VERY PRECISE. The disagreement comes in to play when theists like to call this fine tuning the act of Design (I.D). No one is denying that the universe is fine tuned, there is just a disagreement over the EXPLANATION as we ask why and how.
Scientists may agree that our universe has to meet certain specified conditions in order for LIFE AS WE KNOW IT to be permissible. Thats it. I would go further to say that most scientists would say that the evidence indicates that the life that exists on earth is fine-tuned to the universe which we would expect given what we know about evolution. Besides, your fine-tuning argument isnt really an explanation of anything anyway, because our existence is the result of this supposed fine-tuning, not the cause.
Consider the old puddle example:
Imagine a puddle waking up one morning and thinking, This is an interesting world I find myself in, an interesting hole I find myself in, fits me rather neatly, doesnt it? In fact it fits me staggeringly well, must have been made to have me in it! This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, its still frantically hanging on to the notion that everythings going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for. Douglas Adams
The point being that from the puddles perspective, the hole it sits within was designed perfectly to contain it and therefore must have been made in order specifically for that puddle to be able to fit neatly within it. Its so obvious to us in this case that the puddle doesnt fit into the hole because the hole was designed for it, rather the water the puddle is composed of adapts itself nicely to fit within the hole. In the same way, we imagine that the universe was designed with us specifically in mind, when in actuality, we have adapted to the universe. It appears the other way around because were looking at it from our own perspective.
Lots of people deny that the universe is fine-tuned for life. And you arent doing much to convince anyone that it is. If the universe is fine-tuned for life, then why is life within it so rare?? Do you really think this gigantic universe was created just for us, so that we could exist on a miniscule planet in this tiny solar system that makes up but a tiny fraction available space?
