These kinds of mind games, while perhaps entertaining to some, are useless. If there is no reality, if we are all figments of some unknowable creature's fantasies, how does that change what we can see, and touch, and smell, and hear? If the world we perceive around us responds as though it were real, then it is real. If, rather than thinking up all sorts of inane excuses for why it is not real these philosophers could devise some way of proving the existence of this unknown creature then they might have done something useful. And your statement about science is not quite right. If you can repeat an experiment many times, with predictable results, then it is most probably true. It only takes one failure to change "most probaby" into "not".
Science has, through thought experiment, created the laws it says govern the universe.
Again, not quite. Science has created these laws to explain the forces, discovered through experimentation and observation, that seem to govern the universe. And if experimentation or observation in the future shows that these laws are not right, then they will either be changed or eliminated to explain the universe more accurately.
It has also created another set of laws to explain the difference between the reality the physics of science predicts and the reality that we all perceive ... and this second set of laws is more mind-bogglingly wierd than any description of divine creation.
I'm not sure what these other laws you're talking about are supposed to be. If you're talking about quantum physics then yes, it is "mind-bogglingly weird". It's far beyond my capacity to understand, or to explain. But it's my understanding ("belief", if you insist) that without the understanding of quantum mechanics we wouldn't have computers. And it still explains what we see around us better than any creation fable.
It may be, as I have heard recently, that the uncaused and spontaneous emergence of a material universe where there was nowhere before, and no
before until afterwards, is an inevitability, because "non-existence" is such a volatile condition that something is bound to happen. But that's just another thought experiment, not a statment of what is, or was.
The problem is that we don't know that the big bang was uncaused. We don't even know if there was a "before", much less that it was non-existence. There is nothing in our science which can penetrate the initial point of the big bang. There may well have been gods aplenty, and they decided to merge themselves into a huge ball of matter and thus initiate the big bang. An amusing story, perhaps, but certainly no less plausible than any other myth. But if it did happen that way there is no evidence, so far, that those gods survived creation to inflict themselves upon our universe.
It may be true that everything is because it always was and ever will be, but neither believers nor many scientists support that idea (which might be a point in its favour).
This is similar to a concept that I've toyed with over the years. I have no evidence for it, and I'm certainly not a physicist or cosmologist with the background to take it further than I have. But I've often wondered why people can accept the idea of an eternal God but cannot accept the idea of an eternal cosmos? Always was and always will be. We know (as well as we can know anything) that nothing can be destroyed, only changed. So we can envision the universe, an infinite cosmos perhaps, filled with whatever the most fundamental particle of matter or energy may be. And periodically, over vast unmeasurable expanses of "time", these particles begin to clump together, gradually building what we have termed the cosmic "egg", until a certain critical point is reached and it erupts into a new universe like the one we see all around us now. Who knows? There may be many universes out there, all in varying stages of expansion. All gradually reducing themselves down to that same fundamental particle within the surrounding cosmos.
And if you ask where those fundamental particles came from originally, my answer is that they came from the same place your god came from.
But I suggest that the creation of everything out of nothing by no Prime Mover is just as preposterous an idea as the one that says God started work on Sunday, finished on Friday, and spent Saturday watching football.
But can you explain what created your Prime Mover? And even if we do accept a Prime Mover, what evidence do we have that He has any interest in us or our doings? For all we know, this universe around us may be no more than the equivalent of dung from a passing animal, left beside the trail with no further thought.
So, Thorne, if you decline to attempt to prove the non-existence of God, I challenge you to prove the truth of an uncaused physical universe.
While nothing would please me more than being able to prove the non-existence of God, or any gods, such a task would be far beyond my meager capabilities. But one possible start is this bit that I've taken from the book, "God: The Failed Hypothesis" by Victor J. Stenger. This has been termed the lack of evidence argument.
1. Probably, if God were to exist, then there would be good objective evidence for his existence.
2. But there is no good objective evidence for his existence.
3. Therefore, probably God does not exist.
Granted, this doesn't prove that there are no gods, but it shows the difficulty of proving a negative. After all, a True Believer will simply assert that God doesn't want any evidence of his existence to be found. Or he can say that the evidence is there, but you can only see it through the eyes of faith. How can I, or science, refute such claims?
Libraries are filled with books on both sides of this argument and it would take far more space and time than I'm willing to devote to go into any real detail. So if you want to take that as declining, then so be it.
As for proving the truth of an uncaused universe, the same problem applies. There is nothing (so far as I know) that can penetrate the singularity that we believe started the universe. There is just no way (yet) to gain evidence to support any claims anyone might make.
But I do thank you for believing that I might have the sufficiently irresistible power to move the immovable object.
