The Big Bang Vs. the Big Rumble

WBUR radio in Boston hosts a talk with two physicists, Alan Guth and Neil Turok, who represent, respectively, the consensus theory of the inflationary Big Bang and an upstart theory of the initiation of the universe in the collision of two three-dimensional "branes." Turok and Paul Steinhardt developed their "Ekpyrotic proposal" out of the mathematics behind string theory. In the audio the two physicists are perhaps more respectful of one another's views than the host wishes them to be. If you ignore the "let's you and him fight" framing of the debate, you will hear some interesting physics elucidated.

      Sometimes the Timecube site looks remarkably like the Dada "performance art" pieces that Man Ray assembled, rather than serious output from a mentally ill person.

      Warning, warning, I'm in the Lambda-CDM/Cosmic Inflation/General Relativity/Standard Model camp.

      However, one of string theory's central hypotheses is that: "within the framework of string theory, there exists a false vacuum energy (string background) in which one single free variable -- the string tension -- can be used to accurately describe all particle interactions at any scale". There are reduced version of this, such as: "there exists a combination of the string tension and a range of Calabi-Yau spaces which are as accurate as QFT in Miknowski space" (i.e., string theory does no worse than QM in flat spacetime), some of which are arguably "proven".

      The central hypothesis is testable in principle, in that the range of false vacuua is in principle countable. Indeed, there is a counter-hypothesis which asserts that no incorrect false vacuum energy exists in which string theory can accurately model all particle interactions, which is directly testable by choosing a ground state and computing masses and Yukawa couplings.

      (Note that the counter-hypothesis is believed to be false, and there is aggressive work to try to find ways in which two different ground states may grind out identical particle masses and interactions, and the thresholds at which "identical" values diverge.)

      It is computationally expensive to write down a list of particle masses and interactions for any given ground state, and the number of possible ground states is extremely large. There is no obvious technique for narrowing the search space to usefully small numbers, nor is there any agreed-upon technique for making the per-state computational cost considerably cheaper. However, this does not actually render the central hypothesis untestable in principle.

      I'm not involved in the hard sciences, but I have done more research on the history of science and philosophy than anyone really should. So without understanding the scientific and mathematical evidence for any of the cosmological theories presented here (or anywhere), I have to question why you would say that until they think of a way to test for the existence of what are at present theoretical constructs, it isn't science.

      Please keep in mind this isn't a flippant, trolling comment - I would actually like to hear your response. I ask because throughout history there have been radical new theories proposed in every scientific discipline, and almost without exception they have been dismissed and ridiculed by the mainstream scientific community right up to the day they were proved correct (that's not to say that they were all correct, but that even the theories that were eventually proved correct were very often dismissed as bunk until they were shown to be valid).

      The development of a theoretical model supported by mathematical proofs will, if it is a valid theory, eventually lead into experimentally provable predictions - this is a basic principle of science. But simply because the theory has not been refined to where it can provide a provable prediction with current technology or methods doesn't, in my opinion, mean it isn't science.

      Another poster above said essentially the same thing - that theoretical researchers aren't real scientists. Why is this opinion popular among the scientific community? Is it because string theory has been around for decades, and has been constantly refined or forked, all the while without providing an experiment to support itself? I don't think there should be a time limit on this - string theory is one of the more complicated physical theories, and if it took another 50 years to provide an experiment, and in the end it was proved correct, it wouldn't be any less valid.

      Physics and high level mathematics are not my areas of expertise, so I could easily be fooled by a superficially workable but fundamentally flawed theory. It seems to me, though, that there are a lot of really intelligent people out there who understand the universe much better than I do, and a large number of them support the notion of string theory, in one form or another.

Your argument that there is a lot of distance between Portugal and Brazil, while there isn't between the Netherlands and Germany however has nothing to do with if what is spoken in all those places are mere variations of the same language, or different languages.

      And the first of those is a variation on the Dutch language, one that is distinctively different from what is spoken in the Netherlands, but not so different that people speaking those two variations will have trouble understanding eachother beyond the scope of very simple things, without having to learn eachothers 'language' first.

      And that is unlike for example a Dutch and a German speaking person trying to have any kind of conversation that isn't limited to very basic things.

This means that if you fall into a black hole you would pass the event horizon in less than a second, but people would see you falling for eons and you would seem to have frozen. You would see the universe move faster and faster and you would see the end of it.

      If time flows continuosly it means that inside the black hole the time flows in the opposite direction. This means time flows backwards, so if you could see inside a black hole, you would see things going into the center, but inside the black hole things move in the opposite direction.

      Firstly, I am firmly in the GR/SM/BB/CI camp. I don't despise or despair of string theory, which could be useful if true, but there are approaches within general relativity and the standard model and extensions thereof that are likely to be as useful for analytical cosmology.

      String theory has two central hypotheses, namely firstly that there exists a de Sitter-like metastable vacuum in which string tension is the only free variable required to accurately describe the masses and interactions analogous to those in the Standard Model, and secondly, that there are means for selecting that precise false vacuum energy state.

      The second is especially bedevilling.

      It is provable in principle, but difficult to test, since the search space of ground states is vast, and the computation required to calculate particle masses and Yukawa couplings for any selected ground state is substantial. A brute force search is presently infeasible, and substantial narrowings of the search space have been based on astronomical and terrestrial observations consistent with General Relativity and the Standard Model (and some extensions of the latter). This leads to the charges of string theory being "untestable" (it isn't) and "incapable of producing (useful) hypotheses" (it does). The problem is that attacks on the central hypothesis are much more difficult to test experimentally than is spacetime curvature, and many string theory landscapes can generate approximations of the standard model to within experimental error margins for the most easily tested particle masses and interactions.

      The SM and GR frameworks by comparison have a substantial number of parameters and have occasionally had to increase the number of them. String theory appears to resist this on the face of it, however it also appears to introduce awkward geometry problems involving extra spatial dimensions. The bright side is that those geometry problems arise from (and can be answered by) calculations from first principles for a given ground state. The dim side is that it is not clear how objects embedded in multiple dimensions interact in the dimensions unfamiliar to us, or how those dimensions scale over time (are they subject to metric expansion at the same rate as the classic three spatial dimensions, and if not, why not?).

      Note that extra dimensions (particularly very shallow ones) and both the standard model and GR are not fundamentally incompatible; there is just no reason to rely upon them as there is neither need nor evidence for them in terrestrial experiments involving the strong nuclear force, the weak nuclear force or electromagnetism. Some string theory landscapes require extra dimensions for some or all of these, and for gravitation, and for the metric expansion of the classic four spacetime dimensions. M-theory cosmology is an attempt to raise hypotheses related to the utility of these extra dimensions with respect to the expansion of the universe and gravitation that may work effectively in areas where GR runs into problems with renormalization and the standard model has problems associated with background dependencies and the variations of interactions within changing coordinate systems.

      It is not that string theory necessarily explains how gravity arises as much as that it could model gravitational interactions at planck scales at least as accurately and with less work (no counterterms, far fewer free variables) than the standard approaches. This would be enormously practical in the study of events embedded in strongly curved spacetime.

      However, in the absence of an agreed upon string theory landscape (or even really a method for selecting a workably small range of landscapes), there is close to no additional utility, and you can expect the occasional announcement of a variety of options being precluded by new observational data.

      It had been limited by power too - generating more than a few horsepower (with actual horses) is also fairly new, and has enormously increased our exploration ability.

It uses some well-known reasoning tools, notably the scientific method, in order to make this more efficient. It deals in matter-energy only in the sense that there is no evidence for interactions with anything else but matter, energy, and the spacetime they are embedded in and deform, although most branches of science don't really approach their areas of study in those terms.

      "Mind" is probably an emergent property of "brain", which can be studied directly.

      "Spirit" is probably an emergent property of "brain", too, as an obvious self-estimation/self-definition hypothesis to consider.

      One could consider "mind" and "spirit" as analogues to software (I often do, with the brain as hardware upon which it runs), although computer software is ultimately the direct product of "human brain", and often traceable to specific brains at specific times, i.e., we can reduce it to matter-energy embedded in spacetime.

Tools like fMRI (to study the deoxygenation of blood as it passes through the living brain) and PET (to study the distribution through the living brain of radioisotopes artificially bound up in a variety of biological molecules, like sugars, amino acids and neurotransmitters) represent only two of several useful neuroimaging techniques which are already probing the answers to that question (among many others about the way the "mind" works within the brain).

      The meta-hypothesis is that those answers are findable within a system governed by the scientific method.

      It is in this realm, that God, who is not physical, reveals certain things

    Nice talk, but not one person wanted to mention the behemoth lurking over cosmology today,...

    That would be Burkhard Heim's unified theory from the 1950s. His work brought up the idea that gravity comes in several varieties, only one of which is experienced by us puny beings (so far). One of his additional gravitational entities is, today, called "Dark Energy" although he named it "Quintessence." It is the other, however, which is the "elephant in the room."

    Heim deduced that a messenger particle he called a "gravitophoton" could be produced by using a very intense magnetic field (>20 Teslas) to produce electron-positron pairs from the background vacuum. The gravitophoton would have two types, attractive and replusive. Sound fanatasic?!

    Uh, uh! Last year, the findings of two+ years of careful experiments with rotating, superconducting disks were announced by the European Space Agency (ESA). See http://www.prweb.com/releases/2006/3/prweb364473.h tm . A non-Newtonian gravitational field has been conjured up and made to produce a measureable force in one direction and, upon accelerating the super-conducting disc in the opposite direction, have that non-Newtonian gravitational field produce a force in the opposite direction!

    This makes talk about 'branes and Big Bangs idle chit-chat. Nor are these results a one-shot fluke. Two-hundred-plus runs were made, and the results studied for eight months, before the scientists doing the experiments could convince themselves that they weren't nuts! Their published work is here -- http://esamultimedia.esa.int/docs/gsp/Experimental _Detection.pdf

    Of course, well-established scientists don't need to hear about this. It sort of means a lot of what they know is wrong.

    1. Re:What about the elephant in the room?... by Anonymous Coward · · Score: 0

      Quintessence is not the elephant in the room. Guth's work on Cosmic Inflation specifically allowed for quintessence, and modern work in the Lambda-CDM model tries to be accomodative of equations of state of dark energy (w) other than -1, simply because there are so many unknowns about the cosmological constant.

      CI predicts gravitational waves with a specific tensor-to-scalar ratio (r < 0.55, derived from the energy scale of inflation). WMAP and lensing studies have produced evidence of this, however Lambda-CDM models which do not preclude this value of r and which have -1/3 > w > -1 exist, but are incompatible with cosmic inflation in general.

      Quintessence theories sometimes fit into that r,w space and sometimes into w < -1. The latter space generally requires a non-standard form of kinetic energy which is incompatible with Newtonian mechanics readily testable on Earth, or an r value that is not supported by observation. The former generally requires some form of dynamic change to w to account for the Hubble flow, or the complete rejection of Doppler redshifting. There has been no satisfactory argument against Doppler redshifting accounting for the Hubble flow (and many attempts!), which leaves us with r < 0.55, -1/3 > w > -1.

      The problem with these theories is the nature of the tracker function, which is highly background dependent and not fully covariant. Consequently, an event consistent with the conversion of a quintessence field's radiation-like mode to its anti-gravitation-like mode would have to be shown in Minkowski spacetime (not just through distant observation), which is experimentally plausible but has not been demonstrated.

      Well-established cosmologists would like to hear about this, because rather than undoing work in cosmic inflation and the post-inflationary univierse, it would begin to provide some answers about the nature of the universe before the inflationary epoch. (That is, the tracker function would be assumed to apply to the era well before initial recombination, not just before matter-radiation equality; currently the tracker funciton is assumed not to exist at all, as it is not necessary while w continues to be measured at very very close to -1 with a couple sigmas confidence -- nonevolving post-inflation quintessence is identical to the cosmological constant for all practical purposes).

      In short, the ESA experiment is evidence that favours Guth's flavour of simple Cosmic Inflation after the initial decay of a highly energetic false vacuum to a false vacuum with a lower energy ground state. It does not explicitly exclude other pre-inflationary states, but other evidence does bound its size and energy in ways consistent with the ESA extraction of energy from the current false vacuum (much like Casimir's results, which were already known decades before modern metastability event hypotheses were advanced).

      In short, this is much more interesting with respect to work in the areas of gravity quantization as a constraint upon the gravitational force carrier characteristics than it is to early-Universe cosmology (since it is not highly reliant upon exact behaviours of particles in highly curved spacetime in which frame-dragging is an important effect), and there really are no "well-established scientists" in those areas.

      Firstly, this is the last line from the Tajmar et al e-print itself: "And our experimental results should not be too surprising as they are predicted by Einstein's general relativity theory and the presently observed amount of dark energy in the universe."

      The Tajmar experiments you link to studied the gravitomagnetic London moment of Cooper pairs. The London moment is the alignment of the spin axis and the magnetic field axis, which is expected behaviour in General Relativity following the GEM equation. This is handy for closely approximating electromagnetic coupling near the weak field limit of GR and in Minkowski spacetime, by treating the magnetic force as an analogue of gravitation, making the latter amenable to Maxwellian calculations.

      In very very simple terms, it is the study of the tendency for nonrotating objects in free fall above the axis of a rotating mass to themselves rotate about the same axis; the Tajmar experiment introduces free electrons in a superconductor to test this at a quantum level, and got useful (and predicted) results.

      This is essentially a further validation of General Relativity and the Lambda-CDM model, as well as an interesting approach to avoiding the divergence problem in a well-limited system by linearizing Einstein field equations involving the cosmological Lambda term.

      In short, Tajmar's experiment is evidence in favour of the current consensus on the big bang and cosmic inflation models, which it deliberately set out to test.

      Secondly, graviphotons do not enter into Tajmar's experiment in any form, especially not in the form found the "gravito-photons" (Heim's spelling) in Heim theory. The modern use of "graviphoton" (your spelling) is only slightly related to the Heim theory particle in one of the two main models in which one will encounter the word (with either spelling). The term now refers either to as a superpartner of the graviton (in supersymmetry extension theories) or as a particle that excites the metric tensor in some Kaluza-Klein flavours of string theory (where it literally means "heavy photon", and has nothing to do with the mediation of gravitation per se; KK spacetime deforms in the presence of mass (i.e., the metric tensor is relaxed or excited)). Both extended supersymmetry models and KKstring models as classes do treat gravitation as non-Newtonian, because they are fully relativized (in the sense of general covariance) -- the former deliberately entirely consistent with General Relativity in order to probe various superstring theories, and the latter to a five-spacetime-dimension variant of General Relativity. KKstrings have largely been abandoned in favour of M-theory and other flavours of string theory in which there are larger numbers of spacetime dimensions, and fewer free variables.

      Finally, there is no relationship between the Tajmar experiment and Podkletnov except for a highly superficial similarity in one piece of apparatus (rotating superconductor). This superficial similarity is obviously open to abuse by unscrupulous people whose hypotheses were not explored by the Tajmar experiment at all.
