From: Ken S. Tucker on 11 Nov 2008 17:11 Hi to all. After extended consultations, we have decided, from the GP-b and the LIGO null result to move forward using the physics herein, http://physics.trak4.com/ to improve accuracy. The revised General Theory of Relativity is based on the General Principles of Relativity (GPoR), but we now designate that as the Theory of *Unitivity* embodied within Eq.(4) here, http://physics.trak4.com/GR_Charge_Couple.pdf that is in accord with Modern SpaceTime, (MST), and see the departure from "flat" Euclidean measure "X^2" by *charge* relations "a.b" yields the "S^2" in all intrinsic NonOrthogonal spaces. The physical meaning of that departure is quantized by "a.b" which has units of action, "h". In geometry we can have a long adjecent and hypotenus with an opposite that is quantized (by "h") to form the spacetime curvature. Regards Ken S. Tucker

When a youngster, my Old Boy had a napthalene filter that was such a fine screening that naptha would go through but not water. Said fliter was ~ 40mm diameter and that matched my refractor telescope objective lens. Placing that on the front of the objective lens then created a sort of diffraction grating effect, observable at eyepiece when viewing stars, white lights, red lights etc. The observation is easily repeated therefore scientific. I'll do a poopy ascii Fig fielded with dots as the background, of what I observed from a point (star) light O, ........Y ......../\............. ........||............. .....<==O==>........X ........||............ ........\/............ The screen was cartesian and so was the dispertion rendering a spectrum extending from O, that rotated as the screen was rotated. The spectral effect was symmetrical from O along axes X and Y, with red being at the extremes. In adjuct to theory, the above experiment provides a means for nearly any sighted theoretician to confirm, and from that make their own conclusions. This post may appear Off Topic, but if perchance it is accepted, we may gain insight into diffraction grating theory, and from that insight into the "single slit" experiment. Regards Ken S. Tucker

Ok, how does an inelastic scattering assumption explain the heating of a transparent atmosphere, by sunlight? Well I think it does NOT. In the above ref is a macro scattering, (Rayleigh) of *elastic* scattering. I'll suggest (presume) sunlight heats atmosphere prior to contact with Earth's surface, then the energy lost by the scattering would transfer kinetic energy (heat) to the air and would need to red-shift the light as it surrenders energy to heat the air, of course "transparency" depends upon absorption between the frequency and the medium, such as *spectral absorption*.

Apparently the 3 magnetic field components expressed in a 2nd rank tensor fashion as B1 = F13, B2 = F13, B3 = F21 seems tight in 3D, but then another 3 Electric field components are conventionally, E1 = F14, E2 = F24 , E3 = F34, for a total of 6 vectors in 4D spacetime, meaning one really has a problem jamming those 6 vectors into 4D, ((apart from antisymmetric metrics)). That those 6 are required can be understood by an analysis of dipole EM Radiation, as a measureable Current and Voltage cyclically creating a Magnetic field (via current), then an Electric field (via charge). > F.

Consider the E1 = F10 as, F10 = &A_0 / &x^1 - & A_1 / &x^0 The 1st term on the RHS is gets an E= q/r^2 E-field. The 2nd term is an induced electric field, like a magnetic moving through a coil to create a voltage (E-field) as the basis of a generator. ((correct me if I'm wrong though)). > Peter Regards Ken S.

I lean toward Oz's thinking, by setting up 8 satellites at the corners of a large cube enclosing a space, "within our universe", was Oz's caveat, that is important. An observer at any corner can use relating 3 laser's along x,y,z to the other observers to survey the cube. If the laser's directions are accurately measured, then a sum of the relating angles (90,90,90) in Euclidean space may differ to be (89,89,89), indicating a mass within the cube. Even if the angles were (90,90,90), that cube may have a non-zero mass density and be embedded within a region of a non-zero mass density that is homogenous, enclosing a space containing matter, the observers cannot measure. The absence of a measurement only means anything can be there. Regards Ken S. Tucker
