'Theory of everything' tying researchers up in knots
 Keay Davidson, Chronicle Science Writer
Monday, March 14, 2005
The most celebrated theory in modern physics faces increasing attacks from skeptics who fear it has lured a generation of researchers down an intellectual dead end.
In its original, simplified form, circa the mid1980s, string theory held that reality consists of infinitesimally small, wiggling objects called strings, which vibrate in ways that yield the different subatomic particles that comprise the cosmos. An analogy is the vibrations on a violin string, which yield different musical notes.
Advocates claimed that string theory would smooth out the conflicts between Einsteinian relativity and quantum mechanics. The result, they said, would be a grand unifying "theory of everything," which could explain everything from the nature of matter to the Big Bang to the fate of the cosmos.
Over the years, string theory has simultaneously become more frustrating and fabulous...

String theory is not without its critics in the physics community. I saw this article mentioned over at Peter Woit's blog,
Not Even Wrong. Woit, who's quoted in the article, detests both string theory and the effects it's had on hiring, promotion and tenure decisions in physics departments around the country. He's not exactly a voice crying out in the wilderness, but he's nearer the outskirts of town than the town square.

Ledbetter and Bezant actually saw what they called the Ultimate Physical Atom(UPA)in the 1920's using micropsi(seeing with matter waves). If you are interested, the article is in a past issue of Infinite Energy Magazine. See . They verified the string construction of subquarks.

Yes, yes, yes, they know it all better ... so there is a theory for that and a theory for this. Reality is they know squat.

I saw a two hour special on String Theory not long ago. In order to get the inconsistencies between quantum mechanics and relativity theory ironed out, the math becomes very complicated and you wind up with something like eleven dimensions. Scientists admitted that no one seemed capable of really understanding the implications of the theory and being able to convey it to each other, let alone a skeptical public.
My own belief is that as you bore down to an essential underlying theory of everything, explanations should become simpler and the math more elegant, not more complex.
My instinct tells me that String Theory is just a rickety scaffold for mathematicians to play on before the next genius comes along to show us how everything really works.

It's happened before. In the 1960's, all the theorists were into dispersion relations, Smatrices, Pomerons, and Regge poles. A few mavericks worked with quantum field theory, but most people regarded it as a dead end. Nowadays everyone works in quantum field theory, and those other formalisms aren't used.

Mine is only a layman's view of all of this, but I think it's a rather appropriate irony that as we get closer and closer to the ultimate nature of reality, the more unreal it becomes.
It does seem that high energy physics has indeed been spinning it's wheels for many years now. It wouldn't surprise me if, in the coming years, some little fellow from Pakistan comes along with a completely new perspective that tosses the last two decades of work out the window.

My own belief is that as you bore down to an essential underlying theory of everything, explanations should become simpler and the math more elegant, not more complex. That's my opinion too, but I'm hardly an expert in this area. In the past, the great scientific work seemed to simplify the world, and describe it in ways that were relatively easy to understand. If I'm to understand anything more, there needs to be a new simplification, not this 11dimensional beast that seems to be the most promising bridge between the Einsteinian and the quantummechanical world.
It's a bias  and a hope  built on my own limitations, but my suspicion is that deep down, and I mean way deep down, the universe is based on a few very simple rules.

We don't lack ideas; those we have in spades. The problem is that we don't have any new experimental data that we could use to separate the relevant ideas from the irrelevant, the good from the bad, the useful from the useless. The highestenergy accelerator in the world is the Tevatron at Fermilab, which was built in the 1980's. We now have a pretty good handle on the physics at that energy scale; to get any deeper understanding requires more energetic collisions.
In the next five years a higherenergy accelerator will finally come online, the LHC at CERN. Then we will be able to resume progress.

Thank you so much for the ping! This was an interesting article revealing a bit of infighting among physicists wrt string theory.
IMHO, it points to an ideological difference which would stem from the priority given to pure mathematics in physics. Indeed we've seen similar disputes here on the forum between those of us who center on the mathematics (information theory, complexity, etc.) related to evolution and those who center on the sciences (biology, chemistry, genetics, paleontology) .
It is a philosophical difference which I believe we would all benefit from exploring.
Personally, I fall on the “math first” side of the debate – I put mathematics above all sciences  and physics at the top of the science heap because of its integration with the mathematics.
My reasoning is that mathematical structures are universals per se and thus their discovery sheds light on all the sciences. As an example I assert Einstein’s ability to pull Riemannian geometry offtheshelf to describe relativity. Other examples include dualities and mirror images  the "unreasonable effectiveness of math".
An example related the subject of this article  some string theorists like Vafa (my personal favorite) treat the physical ramifications of their work as secondary, e.g. he was not troubled by the consequence of an additional time dimension in fTheory though it caused quite a stir in the physics community at large. IOW, good mathematics may not be widely accepted or have an application at the moment, but will remain "on the shelf"  because they are universals, which may be relevant at some other opportunity.
Additionally, even if physicists were not pursing a "theory of everything"  the mathematicians would. As an example, here's a link to Jurgen Schmidhuber's Algorithmic Theory of Everything.
I’d love to hear any arguments for why mathematics should not be given a higher seat in our body of knowledge than science!
One last point  I do agree with everyone here who instinctively believe that mathematical truths ought to be conceptually simple. The KaluzaKlein based compactified string theories are not without competition, e.g. the easy to comprehend noncompactified 5D higher dimensional dynamics.

I’d love to hear any arguments for why mathematics should not be given a higher seat in our body of knowledge than science!Mathematics asks different questions from those in the sciences. In turn, the various sciences ask different questions among themselves.

Great insight! But do you see the mathematical structures as universals or merely a box of tools for the sciences?
To: Physicist
We now have a pretty good handle on the physics at that energy scale; to get any deeper understanding requires more energetic collisions.Don't want to harp too much on this.
However, I lament the demise of the SSC. Sigh. What is done is done though. We will press on with the new tools that are upcoming. :)
To: AlamoGirl; snarks_when_bored
Mathematical structures are universal and some of them can be used as a box of tools for some sciences.
The problem with String Theory is that it is a machinery that takes a very long time to handle for the average PhD physics student. When you have been struggling with the mathematics for several years it still does not give you a nice answer as the equations are very difficult to calculate. We need a Witten II that can provide some insight and exclude some of the possibilities that so far are possible in String Theory.
Until that person will materialize my advice to a young PhD candidate is to stay away and go into some other fields of Physics. Note, I am not saying that String Theory is wrong, I just do not know.

You sent me into a vortex of philosophical musing with that conjecture, thus I am pinging the philosopherFreepers for their input. Thank you so much for the challenge! As for me, string theory is only an alternative geometric for space/time and therefore corporeals, cosmology, etc.  the great meaning is in the universals, an interpretation that everything is a mathematical structure which exists apart from space/time dimensionality (the Max Tegmark Level IV universe, radical mathematical Platonism).
From that perspective, everything physical (and perhaps nonphysical as well)  including the geometry and string vibration, fields, waves, particles, properties, organisms, etc.  actually exists in elegant simplicity which (at this time) is beyond our grasp from within a 4D (visual, mental limitation).

You and I have disagreed in the past on that lightning rod of subjects (crevo) which I have no intention of reopening at this time.
Your comment, quoted above, however, I could not agree with more. My personal belief is that for these "few simple rules" to be discovered and understood, seekers of the truth will have to step outside the box of their own scientific disciplines and realize that there literally is no spoon  that consciousness itself is the stuff of the universe.

Indeed. Seems like every discipline has things which we can know, things which we do not yet know, and things which we can never know.
Concerning the unknowable  in mathematics, we have Gödel's Incompleteness Theorems. In physics, we have Heisenberg's Uncertainty Principle. And in the historical sciences  evolution, archeology, anthropology, Egyptology  we have an incomplete record of evidence.
To me, all of these are cautions which attach to the value of evidence and/or work product  but not to the value of the discipline itself.
To: AlamoGirl
My copy of the new Goedel book just arrived. Incompleteness: The Proof and Paradox of Kurt Godel by Rebecca Goldstein. It is highly recommended as the author is a good writer and an actual philosophy of science prof. I have read the first couple pages and already it is getting heavy. This will be good; Goedel is variously estimated as the greatest logician since Aristotle.

Reification of mathematics. The map is not the territory. Mathematics is a map and does not "exist apart from space/time dimensionality" (or apart from the mind of man, for that matter.) If it did it wouldn't matter anyway because, by definition, we could never know that. Such radical Platonism would be unknown and unknowable.

This is the tension between the Aristotlean worldview and the Platonist worldview with reference to math. The Aristotles would say that the mathematician invents the mathematical structures. The Platonists would say that the mathematical structures exist and the mathematician only discovers them, e.g. pi exists, it was only discovered.
Tegmark: Parallel Universes According to the Aristotelian paradigm, physical reality is fundamental and mathematical language is merely a useful approximation. According to the Platonic paradigm, the mathematical structure is the true reality and observers perceive it imperfectly. In other words, the two paradigms disagree on which is more basic, the frog perspective of the observer or the bird perspective of the physical laws. The Aristotelian paradigm prefers the frog perspective, whereas the Platonic paradigm prefers the bird perspective....
A mathematical structure is an abstract, immutable entity existing outside of space and time. If history were a movie, the structure would correspond not to a single frame of it but to the entire videotape. Consider, for example, a world made up of pointlike particles moving around in threedimensional space. In fourdimensional spacetimethe bird perspectivethese particle trajectories resemble a tangle of spaghetti. If the frog sees a particle moving with constant velocity, the bird sees a straight strand of uncooked spaghetti. If the frog sees a pair of orbiting particles, the bird sees two spaghetti strands intertwined like a double helix. To the frog, the world is described by Newton's laws of motion and gravitation. To the bird, it is described by the geometry of the pastaa mathematical structure. The frog itself is merely a thick bundle of pasta, whose highly complex intertwining corresponds to a cluster of particles that store and process information. Our universe is far more complicated than this example, and scientists do not yet know to what, if any, mathematical structure it corresponds.

That might be so. Goedel was the best and in the same league with Einstein and Heisenberg. Too bad Heisenberg stuck to the losing side of WW II, he should have come to Princeton.

There's one issue I'm not altogether clear about. Would the following not qualify as a "prediction" or "experiment" of string theory?

Of course the nature of this CSL1 anomaly remains unsettled, but if this and associated tests were to hold up as indicative of cosmic superstrings wouldn't that affirm that the string theory concept is on the right track?

A little followup on your previous post, you might find it interesting (I did) that John Baez includes the ADE theory on his website. ADEX is the basis of the Sirag consciousness model.
To: AlamoGirl
The mere fact that Sirag is mentioning something does not mean that it is right or wrong, it is the way he connect it to other things. The totality of what he writes is still crap. Sorry for that.
