The physical problem of general relativ...To Ulla:<br /><br />The physical problem of general relativity is the lack of Poincare invariance. One can argue that it is obtained by approximation metric with flat metric locally but personally I am skeptic and believe that here lies the basic reason for the failure to quantized general relativity. For some reason, people refuse to take seriously the loss of Poincare and Lorentz symmetries.<br /><br />In TGD framework imbedding space provides the Poincare invariance and it has turned out that this dramatically simplifies the interpretation and application of the theory.<br /><br />Concerning you question. The treatment of spinor components as scalars is certainly wrong. <br />It is certainly true that in curved space-time the action of Lorentz group on spinors is not straight-forward since Lorentz symmetry as isometries is lost. One can however ask how general coordinate transformation affects spinors. <br /><br />The introduction of spinor connection makes it possible to define the action of general coordinate transformation as a gauge transformation on spinor field. Spinor components would *not* be scalars but behave like spin 1/2 objects as one might indeed expect. One might perhaps say that Lorentz group would become gauge group.<br /><br />The fact is however that it is not gauge symmetry but genuine symmetry and again TGD raises its head;-). <br /><br />General Relativity has also other difficulties. For a generic space-time manifolds there exists no spinor structure! CP_2 is one example: in this case however there is very natural manner to generalize spinor structure and this leads to a correct prediction for standard model symmetries. <br /><br />As a matter fact, Hawking was one of the colleagues who showed interest to CP_2 at the period when everyone talked about instantons and they discovered the generalization of spinor structure but never the fact that CP_2 codes for standard model symmetries!<br /><br />Spinor structure makes itself visible also in a relative mundane conceptual problem of lattice QCD. The treatment of quark spinors in lattice QCD is very difficult and the reason is that the replacement of space-time with 4-D torus implies 16 different spinor structures. This causes the problems. In TGD one has induced spinor structure instead of the ordinary one, and the problem disappears.matpitka@luukku.comnoreply@blogger.comtag:blogger.com,1999:blog-10614348.post-70051029278865954202012-01-12T19:31:36.158-08:002012-01-12T19:31:36.158-08:00Dear Hamed,
this is a good question since it give...Dear Hamed,<br /><br />this is a good question since it gives me a possibility to talk about the notion of coordinate distance and real distance defined by the Riemann/Kahler metric. The basic point is that coordinate distance is not a general coordinate invariant notion since one can introduce infinity of different coordinates and every choice would give different distance.<br /><br />Let us consider CP_1 - two-sphere - as an example. <br /><br />One must introduce coordinate patches which over lap. The minimum number is two. They cover North resp. South pole. If one tries to cover the entire 2-sphere by single patch one obtains a coordinate singularity which spherical coordinates indeed show: at poles all values of phi correspond to the same point. <br /><br />With Kahler structure in mind one could interpret patches as complex planes and North/South pole for South/North patch would correspond to circle at infinity geometrically.<br /><br />Complex coordinate distance would be infinite between poles but the metric distance defined by the induced metric would be just pi*R, R the radius. The metric distance is of course the correct distance.<br /><br />Riemann geometry is the general coordinate invariant formulation for the notion of distance. <br /><br />*One introduces line element ds^2=g_{ij}dx^idx^j and one can integrate distance s(A,B) as Int_A^B ds for any parametrized curve.<br /><br />*One can also define angles in coordinate invariant manner, and the additional bonus is that one obtains the notion of curvature distinguishing sphere from flat plane. Curvature tensor, Ricci tensor, curvature scalar are the outcomes and one has all tools for formulating General Relativity! <br /><br />*Kahler structure is additional refinement: metric tensor represents real unit and imaginary unit is represented by Kaehler form. i^2=-1 is represented by the tensor square J^2=-g. <br /><br />Your question was about CP_2. Radial coordinate r is associated with one particular convenient choice of coordinates (U(2) subgroup of SU(3) is represented linearly and CP_2= SU(3)/U(2) holds true). One can also introduce 4 coordinates that are like angles in analogy with theta,phi for CP_1=S^2. <br /><br />The actual distance is defined by CP_2 metric. For details related to the definition of metric see <br /><br />http://tgd.wippiespace.com/public_html/articles/cp2geometry.pdf<br /><br />By the way, CP_2 requires 3 coordinate patches diffeomorphic with R^4 or actually C^2 since one has complex structure and Kahler geometry. From the representation as complex projective space one can has coordinatization (z_1,z_2,z_3) with all points differing by complex scaling identified so that 4-D space results. One can choose coordinates for one of the patches to be (U=z_1/z_3,V= z_2/z_3,1). You can guess what the coordinates are for other two patches;-).<br /><br /> CP_2 radius could be defined in terms of a length of CP_2 geodesic L=2*pi*R. The length is same for all geodesics related by SU(3) isometries. One can imagine that one restricts consideration to geodesic sphere (two non-equivalent ones) and then takes the great circle to get geodesic circle.matpitka@luukku.comhttp://tgd.wippiespace.com/public_html/noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-8121266482777091702012-01-12T14:40:43.295-08:002012-01-12T14:40:43.295-08:00Dear Matti,

I can’t combine these views together? And on the other hand I remember somewhere in your posts that cp2 can have arbitrary size.<br />When I touch a keyboard by finger, join along boundaries bond take place at each scale at the same time. At scale of atoms and at scale of molecule and even at scale of my finger.(is it true?) For example at scale of my finger, if it is a new kind of force then what is the force? Something like long range forces?<br /><br />What does vacuum means in TGD?

This is not an option in a curved spacetime. Therefore, in the equation proposed independently by Fock and Weyl, the four complex components of the Dirac wave function transform as scalars under a general coordinate transformation.Ullahttps://www.blogger.com/profile/16634036177244152897noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-26697131117725942232012-01-12T10:18:04.528-08:002012-01-12T10:18:04.528-08:00Look here, entanglement between fields or waves?

Enlightment? <br /><br />I have an idea that entropy and negentropy oscillate, entropy creates negentropy that degenerate, again and again. Decoherence (surfaces for flux tubes) are created like waves on the ocean. So the organism is in fact oscillating between wave and particle state. This creates the window-effect of interference and homeostasy (ground level) - allostasy (higher coherent levels) of stability?Ullahttps://www.blogger.com/profile/16634036177244152897noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-30189205517663705832012-01-12T00:33:14.511-08:002012-01-12T00:33:14.511-08:00Photons and electrons are at two places at the sam...Photons and electrons are at two places at the same time =entangled?<br /><br />http://www.youtube.com/watch?feature=endscreen&NR=1&v=-ahoBqSsqXYUllahttps://www.blogger.com/profile/16634036177244152897noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-63184701118647379272012-01-12T00:13:41.809-08:002012-01-12T00:13:41.809-08:00http://arxiv.org/PS_cache/arxiv/pdf/1201/1201.1809...http://arxiv.org/PS_cache/arxiv/pdf/1201/1201.1809v2.pdfUllahttps://www.blogger.com/profile/16634036177244152897noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-60131265752951411762012-01-11T23:59:08.114-08:002012-01-11T23:59:08.114-08:00The radiation from Sun defines the fundamental met...The radiation from Sun defines the fundamental metabolic currency. Solar radiation cannot be said to negentropic since negentropic entanglement is a 2-particle property. Solar photons could possess a large value of hbar or - more plausibly - suffer at the magnetic body of the living system a phase transition increasing the value of hbar. Could the absorption of large hbar photons arriving from Sun or from magnetic body by electrons generate spin 1 valence electron pairs pairs or provide the metabolic energy needed to re-arrange the flux tube connections between distant molecules by ADP+Pi → ATP process? <br /><br />Must entanglement be between particles?<br /><br />The photonic wave ('particle') <b>is created by two parts, electric and magnetic fields, and creates magnetic and electric fields. No magneton is needed. </b> Electrons are transferred from sun, as neutrons are? What happen with all those electrons at Earth? They create spin, vibrations, oscillations, <b>SIZE</b> (=length?). Hbar? Excitations comes from photons (quanta) is it said. Energy that comes from a boson (='negative' or 'shadow' particle, not antimatter) and sprouts forth as em-radiation (=tension, imbeddings), creating <b>time</b>, oscillations, vibrations, spin etc.<br /><br />Antimatter also creates gammarays and gravity in the same way as ordinary matter.<br /><br />The globe is shining? The space not. <br /><br />Mostly em-radiation has no electron at all. What would be the particles then?
