So that's no "unevaluated > assumption". If these theories match the mechanisms acting in the real world exactly, the model and the real world's behaviour should match. But the problem occurs, that a model and what this model tries to emulate, that are different things, since models are abstract descriptions about far more complex things. A model about a naturally occurring phenomenon will gain somehow similar results. But to create such a model is a difficult task. The other question is, if the assumed mechanisms are actually present in that phenomenon. Certainty things in nature happen after entirely different principles than physicists use in models, to predict the outcome of experiments. We could, nevertheless, try to understand natural behaviour, but most likely at the expense, that we cannot utilise such methods in somehow useful models. But more important is: such mechanisms are not known. We only assume the validity of certain assumptions about the fundamental principles, that are acting in the foundations of nature. Even if these principles are understood (what they are not), this would not necessarily help to predict something, since we simply cannot use such long timespans and so many participants, as are present in natural 'experiments'. > CLEARLY you don't understand the provenance of 'shut up > and calculate', or what it actually means.

Your FANTASY here is just plain wrong. There is also the possibility of 'intentional cheating'. I mean, it could be, that physicist intentionally lie to the public, since they try to hide something. If this would be the case, they would need some sort of 'elaborated blunder', to keep people away from what shall be hidden. There are generally four kinds of powers, which belong to the 'usual suspects': - churches of some sort - governments and politicians - banks and large corporations - military and other security agencies So, physicists should be independent of either of these groups, unless you want to think, their finding is wanted by such powers. But blunder of some kind had always been generated in these realms. Actually scientific blunder was not created by - say - politicians, but they have hired scientific personal for this kind of work. And if that is stupid and confusing enough, this blunder is force-fed to the next generation of 'scientists'. The really weird things are honoured. And if it's really far out, it gets published in paperbacks and will become a bestseller. > String theory is a legitimate and serious effort to examine and consider > what might underlie GR and the standard model.

First problem would be, why the assumption is held, that strings of some kind occur in nature. (I would say, it does not even remotely sound like a promising idea.) But maybe I'm wrong and on very small we are composed of tiny strings. This is actually a testable prediction: there are tiny strings. So string theorist should show evidence for at least one of these strings. TH

Wrong again, Gawy. It's *an* alternative (theoretically speaking); > Are you willing to maintain that fictional point objects exist?

If you accept the Big Bang hypothesis you do.

That would be up to those postulating such objects, Gawy. > The physics world is waiting for your brilliance. Tch. Sarcasm. The lowest form of wit. And in this case a gratuitous abuse. You should apologise to Thomas. But being the ranting lunatic that you are, you won't: you just can't help yourself, can you Gawy? There *is* a cure for what ails you, you know. It can even relieve you of that froth in the corners of your mouth. Wouldn't that be nice? You know, I'm thinking that Har Nagel doesn't suit you all that well (you being such a witless wanker and all): I think you should change your name to Fuck Knuckle. Waddya reckon? Gawy Fuck Knuckle. Got a nice ring to it, don'cha think?

I only need a certain relatively simple assumption. This is the assumption, that points may have features. I use the term' elements of spacetime'. That is roughly the same as a point, but not of an euclidean space. Space (usual 3d) shall 'emerge' (like in big-bang-theory). The idea itself is actually simple: Just look at this diagram: https://upload.wikimedia.org/wikipedia/commons/thumb/1/16/World_line.svg/300px-World_line.svg.png This a typical light-cone diagram. OUR (!) past-light-cone is actually, what we call 'universe'. But the 'real thing' is this plane called 'space-like'. Since the diagram is meant as three-dimensional (2 space, 1 time), we need to multiply it by three (to reintroduce the missing dimension). These three planes build kind of space, which is actually real, but invisible. The 'points' there are oriented by nature. And this orientation is connected to the 'neighbours' in a way similar to how quaternions are multiplied, what could be interpreted as rotation. This will generate 'timelike stable patterns' (actually of the orientation vectors) and that is, what we call matter. I have written this 'book' about it: https://docs.google.com/present/view?id=dd8jz2tx_3gfzvqgd6 Certainly an unusual concept, but as far as I can tell, it works on a large number of different problems. To my great surprise (till now) nobody had any interest in it. Certainly it's quite amateurish, but as a matter of fact, I am an amateur. TH
