I see what you're saying, but it's not like a hydrogen atom is figuring out the frequency it should oscillate at: it is constrained to aim toward a particular frequency by purely physical behaviour. That said, the best computer you could design for modelling the universe exactly would be... the universe. You could think of it that way. — Kenosha Kid
That's exactly what I say. It's us trying to figure out what history occurs by trying to calculate them all and assign them probabilities according to a principle. I don't think the universe computes all these different histories, assigns them complex probabilities, and ĺets these interfere. All these procedures are human inventions, not truly present in nature. That's only what we project. You could think of it that way, and that leads to the idea of a track being present.
In reality, almost all elementary processes are reversible. — Kenosha Kid
Well, in theory all processes are time reversible. Just reverse all motion present in the system... in practice this needs quite some effort, and the means you reverse all motion with go forward in time. You can mentally reverse all motion, but in practice this is not possible, and it's the reason time is irreversible. Processes could run in reverse though. If all motion would be magically reversed (evolution of the wavefunctions, collapses, expansion of space, spin), a time reversed universe is seen. Wavefunction evolution is not reversible in time though, and collapse would still occur, so even if the reversed process is possible, the reversed evolution of the wavefunction is not, as collapses are not reversed in superpositions. In practice, reversed processes can only occur if the momenta are reversed, and this can only be done in the bigger context of larger irrerversible processes, and an accidental reversal can also only occur in such a larger process, because else the whole had to reverse in its entirety, which obviously cannot happen.The funny thing is though that it are fundamental processes that are asymmetric in time. The weak force is involved here, as the weak force is left right asymmetric. Some particles (quark anti quarks) are CP asymmetric and thus T reversal shows a different partice, and time reversal can be identified. Somehow, space asymmetry necessitates a form of time asymmetry.
I'm not getting what you are saying makes will free. That it evolves? — Yohan
I'll give it a try. The academic approach to free will or wont is that their freedom is taken away by reference to a natural law, be it a statistical one, like QM, or a deterministic variant of it. In both cases the will seems to be "a victim" of determinism, be it a determined wave function with associated probabilistic collapse, or even a deeper deterministic substrate. It is claimed that the will is somehow the slave of deterministic or probabilistic processes, which denies the notion of a free will.
But how can an evolving process be "determined" by initial and boundary conditions or natural laws? Only if we litterally impose boundary or initial conditions, and project a natural law into it, it makes some sense to say the process is determined. But we can't impose these conditions into the inside of the process. Mentally we can project forces into the process and call these forces the determining entity. These forces though are caused by internal charges. These charges and forces are part of the process and the only thing really determining the process is the will inside it. There is a will even in two charged particles interacting, though I'm stepping her off the beaten track. The dynamics of charged particle fields is not determined by gauge fields but by the will particles have to interact. Physicists call this will charge. Because of this charge (its nature is not understood, not even by string theory, which shifts the problem of charge to vibrational modes of strings, which makes one wonder what causes this vibration) interaction occurs. The charge in a sense pushes the the particle fields, by means of gauge fields. Which is to say, we view it that way. We consider gauge fields the fields causing the dynamics of particle aggregates but can say just as well that the will, the mental, or however you call it, the cause of the dynamics. Two magnets pushing or pulling one another somehow seem to have a will.
Larger, more complicated processes, with complex structured charges moving, like charges running around on the neurons of our brain, involve more complex forms of will inside the body, like charge and colored charges in quarks and leptons or two even more fundamental particles. These charged contents constitute the will and consciousness and the freedom of this will can be constrained by other forms of will.
The will, or consciousness or charge, are not caused, nor do they cause. The will is an inherent property of nature, and so are charge and consciousness. The will can influence other processes. People have a will with eyes to see, ears to hear and mouths to scream. They have the great, and at the same time scary possibility to reign over the will of other people, the will to power. The will simply is, not determined but determined, not caused but causing.
So we are just charged bodies with faces, arms and legs to excercise our will, and an uncanny ability to direct our fellow beings in thought, action and story.
Great story...That's all it is, a bedtime lullaby...
