The question of the so-called "fine-tuning" of the universe and its basic constants is one of the pet arguments of theists. One of the main reasons for it is that there is no obvious explanation
There are essentially four possible explanations:
This fine-tuning is highly unlikely in a random possible universe, but God has ensured in his loving wisdom that it is so, so that we can come into being.
This fine-tuning is highly unlikely in a random possible universe, but just by luck the one that exists is anthropic.
This fine-tuning is highly unlikely in a random possible universe, but there are such a vast number of other
universes that it is not unlikely that at least one of them is anthropic.
There are as yet undiscovered reasons why this fine-tuning is not highly unlikely in a random possible universe.
>>< Which option do you prefer, and why?
I prefer the unspoke option: The universe can be agreed to exist because of a shared sense of something we call reality. We don't know enough to say why something exist instead of nothing, but we are investigating it.
Nothing wrong with admitting that we don't know something, it leaves a puzzle to solve. Preference has no bearing on this "reality" thing, so it doesn't matter.
And how does adding a creator make things more likely?
All that does is add a level(s?) of complexity. Now you have to explain where the creator came from then explain why they chose the tuning details that they did.
Add it up and that addition makes it look even more unlikely to me.
The universe is not fine tuned, it is lethal. Most of it will kill you in an instant.
Think this world was made "just for Us"?
Go visit Danakil.
No. 1 defers the question to an extremely improbable god, so that isn't an explanation
No. 2 begs the question of the universe being extremely improbable, so it isn't an explanation.
No. 3 is possible, but really defers the question by inventing a multiverse that is otherwise lacking any evidence.
No. 4 gets my vote. Why is the speed of light constant at it's value? The finely tuned constants are derived from a level of physics that is still severely defective in not being able to account for a slew of phenomena. Many, many measurements are seen to be precisely off from otherwise precise predictions based on theory. That means the theory is incomplete and missing one or more terms. These elusive missing terms may well dictate the supposedly fine-tuned constants to be what they are. We are still profoundly handicapped in our understanding of physics. And some of it may well be suppressed because of the implications.
Fine tuning fails because it assumes we are the result of some kind of willful effort. As it happens, we are an effect, not a cause, so of course we'll fit into the structure of the universe that we sprang from. Further, the VAST majority of the universe is NOT suited to us. It's just this one tiny speck of dusty orbiting a tiny star on the far edge of a mediocre galaxy. We're NOT the center of the universe, not the cosmic reason for its existence.
Try my reasoning.
I bought a new Chevy yesterday and brought it home from the dealer. After I finish with a lot of fine tuning it might be a good car.
The above is imaginary but it shows that fine tuning arguments for our earth and the universe have to be made by those who embrace evolution in some form. Since we know this is not true, "fine tuning" does not hold up.
It is amazing that the universe is just the way it is and that it is suitable for life. Even more amazing is that anything exists in the first place. I am absolutely staggered by the sheer brazenness of it all. How dare it be so!
I lean toward that last option. Just to say that God did it explains nothing unless you can define and understand God. In the same way, to say that the universe occurred as a random, chance event is equally unsatisfying. What is the system through which all these random events are supposedly occurring? How was such a system established? Where are these almost infinitely numerous other universes and under what overall reality do they exist?
Any honest and aware person is totally mystified, but that doesn’t mean that we can’t move toward understanding. The trouble is that we are trying to fit all of reality into our limited artificial framework of perception and it just can’t be done. Our concept of existence has no real meaning—it’s just symbolic mind-stuff. Our basic definitions and assumptions are sitting on quicksand, and besides that, we don’t understand our selves.
Donald Hoffman’s new book is entitled The Case Against Reality, Why Evolution Hid the Truth from our Eyes. Hoffman has leapt out of the trace-chains of physicalism and is marching off in a new direction. I just started reading, but I’m hoping to gain insights into conscious awareness.
Conscious awareness is like a beacon off on the horizon, barely visible through the fog, but offering hope. That is the direction we need to move in my opinion.
I'm somewhere between explanations 2 and 3, if I understand them properly.
Our thinking about the question, however, is putting the cart before the horse. To say the universe is "tuned" in some way to permit life begs the question, how do we know life would not come about in some other universe with a different set of rules? We imagine that this universe containing life as we know it is the only possible one, because we have a severely constrained imagination. We almost can't imagine what another form of life would be like. It's like trying to imagine what purple sounds like.
This whole notion of "fine-tuning" is just a way of looking at the human-developed math of physics, usually in awe, and then making the pronouncement that "things had to happen in this very precise way for all of this to be possible."
Well no shit, Sherlock. What, the butterfly effect doesn't work on a cosmic scale? Of course it does.
And so what? The math is merely our (still young) attempt to define the rules in ways our dumb brains can understand, and the numbers (aka constants) are just the numbers. It's all very awe-inspiring and (for some folks) fun to think about, but the numbers themselves are not particularly meaningful.
So, this is simple enough. Reject the argument entirely. It's wholly unnecessary.
IF, and that IS a VERY BIG IF btw, this Universe is so 'fine-tuned' by this god entity then why,
A) is there at least 1 planet is this Solar System that rotates on its axis completely OPPOSITE to all the others,
B) Why does our lunar body, the Moon, NOT rotate on its axis when even asteroids, etc, do,
C) Why bother 'creating' literally billions of other Stars, Planets, etc, AND only putting life on just one,
D) Why 'create' things that are harmful to life created, things like diseases, radiation from the Sun, viruses, etc, in the first place,
E) Why is that the planets in this Solar System do NOT orbit the Sun in a nice, neat, well organised horizontal plane like disc,
F) Why have there been Meteors and Asteroids impacting on the earth over the last billion or so years when IF everything is so 'fine-tuned' it could have been prevented from the very beginning,
G) Why create Ice Ages that almost wiped out life on this planet,
There are literally heaps more questions that I could put forward to any Faithfool and would be at least 90% certain of getting the exact same response as " Who are we to question God, he works in mysterious ways his miracles to perform."
NOTHING, absolutely nothing in this, or any other possible Universe is 'fine-tuned,' nature, to some extent, is always very random and never fine-tuned, it only seeks to fine tune ( for want of a better term) life to suit the environment in which it finds itself.
They are still left with trying to explain how such a being, capable of doing all they say it can do, came into existence. It is far less of a stretch to accept that we exist, and likely other planetary life, because "this" universe allows for it than to think some all powerful being has just always existed and has fine tuned it for our existence.
Heck, if it were a being, that created it all for us, one would think it would have made, not only the universe, but our own planet a little more hospitable for us. As it is we cannot exist in space--and least not for long and not without artificial assistance; and, where we can survive here is also limited.
If the universe and this planet were "created" with a creature in mind--it was the tardigrade. They can survive any earthly conditions and even in space.
