He then rebuilt all of his thinking schemes on that footing, starting with identifying what in the material world sustained his thinking process: his brain, then the body that sustained his brain, and so on, and then went on to try understanding what his body and all of the universe was made of at the more elementary level, from what was known at the time. What you probably need is to do a similar exercise, that is, find some absolute reference that you will trust as being absolute. André Miichaud |

So, the assumptions that laws are true is ultimately baseless...though it can be said to be practical. Your stance is compatible with physics. The problems are open. Past knowledge can be broken. However it is up to you to identify such an invalid assumption and clarify it. Then you will have made a contribution. Just to make someone think for a moment may be enough. You are providing the ultimate skeptical position but the utility of skepticism is in finding a weak link and mending it rather than discarding the entire chain. As Mitch points out below you might discard just about the whole chain but you will be caught constructing on some basis which will always be challengable by someone else in the future. We are stuck as prisoners of reality and the fact that we are humans practicing science can only be partially overcome. A principle of improvement cannot be challenged except by your ultimate skepticism. You might be right but the human thing to do is to take the gamble and apply yourself to improving the reconstruction rather than just focus on demolition alone. Find the cracks in the existing structure and they will guide you. I do believe there are plenty of cracks all the way down to the foundation. - Tim It is just like saying that the keyboard you're typing with will work forever just because it's been working till now...since its creation.

We all know that the direct cause and effect relationship between two events is invariant with respect to the temporal or spatial location of the events. In fact, physics is based around it. But, is there any objective proof save for the unit probability of such invariance accounted for by statistical observation in the past? For instance, sitting here on the surface of planet earth, If I let go of a ball, I'm more likely to assume that the ball would go down instead of going up. Some would be very certain that the ball would go down. This is merely because of the unit probability, as observed in the past, of the occurence of such an effect given the same initial conditions. Of course, we have the universal law of gravitation to assert to us that the ball would go towards the center of the earth. But, this assertion by our law cannot guarantee that the ball would indeed go down because the law itself is an generalization attempt made by us to take advantage of the observed unfailing nature of this causal invariance. Objectively speaking, the law is nothing but a tool of convenience that has not failed till now. Imagine this, if the sun is to disappear suddenly and completely from spacetime, should it be of any surprise to us? In fact, what guarantees the continued existence of the sun in the first place? The law of conservation of matter? What guarantees the validity of such a law? There are no courts of physical law in the universe where we can argue over the disappearance of the sun or the lack of enforcement of the law that such an event defies. we'll just have to do with it and modify our laws to accomodate this new "quirk" (i.e. if we're to survive that long without the sun). So, in essence, the only thing that has the capacity to objectively guarantee that the ball would indeed go down when I let go of it the next time is the ball going down when I let go of it the next time. Think about this...the next time you press the key with the letter 'P' printed on it, is there really any guarantee that it will be the letter 'p' that will appear on your screen and not any martian symbol? The only proof that the next time you strike the key, p will appear on the screen is the effect itself. Laws of physics are designed around this *assumed* invariance of causality with respect to temporal and spatial location of the event. There is nothing we can do if this baseless assumption is to falter. Regards. While this is nicely encapsulated, it is not at all new. The fact that there ARE noticeable regularities to nature is precisely what gives rise to science in the first place, and why the scientific method seems to have some measure of success at what it does. Note that science does not even attempt explanations of most unreplicable events, since the replicability is crucial to many aspects of the scientific method. Feynman notes that it is remarkable that there ARE replicable and reproducible behaviors in the universe, which is precisely what science makes note of. However, as you note, no physical law is ever *proven* to be correct. The best we can say is that a law seems to have enormously broad application and an exception has never been found TO DATE. PD |

I frankly don't know the answer...to me, it only suggests that the universe is independent of any active variable and is at the most stable of its configurations (at equilibrium); perhaps that is why the cause and effect relationship is same...however naive this may sound. I think that a partial answer lies in the definition of causality. Under the modern 4D interpretation of time or the classical Newtonian version the same downfall makes its appearance in the mathematical placement or a real number valued time. This model does not admit the unidirectional nature of time. My own investigation reveals that time corresponds naturally to a one-signed type of number which is unidirectional yet these one-signed numbers are zero dimensional. http://BandTechnology.com/PolySigned http://BandTechnology.com/PolySigned/OneSigned.html In that our interpretation of causality is linked to our interpretation of time then so long as time remains poorly understood then so will causality. Could I try another angle? The past is generally considered to be fixed in constancy since it has already occured. Yet we have no ability to observe it. As I look at a wooden chair its spindle was once part of a tree. Where that tree grew is a fact of the past yet my own ability to trace it is highly dubious. We tend to mistake this as a known yet there is a subtle difference isn't there? In such subtleties there may be room to yield a new interpretation and it may result that the very word 'causality' comes into question. Thence determinism would likewise yield under a new interpretation and that relief would be welcomed. My brother has a funny stance on determinism which I assume you see is directly linked with causality. He says that if existence were deterministic and we have no ability to predict it then what does it matter? I like the word 'semideterministic' but its really got to come down to math at some point or else its all a bit hazy. Existence for the human is remarkably stable and yet remarkably dynamic. A theory which yields such qualities as directly as possible is what we are after. In polysign time's zero dimensional interpretation (its graphical nonexistence) along with its unidirectional algebraic existence is appropriate. As Janis Joplin once said "It's all the same ****ing day man." A principle of improvement cannot be challenged except by your ultimate skepticism. .

"How can such laws be trusted upon if their defiance has possibility?" Regards. Yikes. That's a big question. In that the problems are open I do think that we have to be open to such possibilities. But it is in the 'laws' which were broken that we would ammend things. Yes, the old law would be broken by even a singular intrusion though I doubt that such an intrusion would be singular. If we cannot make sense of the situation then we would have to accept that the puzzle remained open for a future solution. Still the scientific community need not be united on such issues. Some will create an interim model that works half way and get tremendous attention. That may be the current situation of both string theory and particle theory. Their laws should not be trusted unconditionally. Especially when quantum physicists divorce themselves from philosophy then I think a trouble has been exposed. I think the proper outcomes are either that a new philosophy will be born out of QM or that QM is wrong. Especially when the level of complexity of the mathematical construction that a theory is built from reaches as far as quantum physics has then I am comfortable predicting a collapse. What they have built is more like a collage than a solid structure. If a cleaner theory exists someone will have to challenge these existing 'laws' rather than merely build on top of them. If laws inherently yield dynamics then such a dynamic reality as you are suggesting is possible. Even a constriction upon the human state that cannot be tested directly by the human (since we are products of the system) is appropriate I think. Though some reject string theory on this ground I find the untestable aspects theoretically acceptable. Still, going so deep I believe it is their burden to derive spacetime rather than manually insert it into such high dimensional theory. If the complexity of physics theory continues to rise without simplification then isn't modern physics consistent with your own belief? To break these laws will be a good thing but I would attempt to break them in the direction of simplification rather than trending with their complexity. Sorry I wrote too much. -Tim |
