From Painius:
*Refinement*, my friend. Not looking to replace existing theory... only to refine it. The expanded model never seeks to supplant or negate the old, but to build upon it, in the sense that Einstein built upon Newton. The new may subsume the old, but never replace it.

Hi oc Painius Odysseus Glad that one universal force(gravity) is being
mentioned ,and all the other forces coming from this one force. When we finally unify the forces. this will be reality That is why my universe equation fits so well. My 'Spin is in theory" tells how electrons work in regard to magnetisim.,electricity,and light. Keep in mind it would not be an electron if it were not spinning(classical spin) All electrons spin at the same speed. That speed is "c" and it is the reason when photons leave this spinning field their speed is "c" The structure of an electron is composed of a field(much like a cloud) of swirling photons. (Weinberg knew that) When smashing the electron with a positron ask yourselves what does it show. My theory on photons answers the twin slit experiment. Gentlemen thinking with gravity and spin in your mind can answer lots of hard questions. Nature gave gravity only an attraction force. She has ways of balancing this inward force with (angular motion) and particles spinning at rest Nature uses spin in all three worlds. Macro,micro,and sub-microscopic. Using QM in the sub-micro world and QM describes a particle as a dot to give this dot an effect nature gave it spin. As far as magnetisim goes all objects have a degree of a magnetic field. This was proven about 4 years ago when frogs,and mice were levitated by a magnetic field. interesting part of this experiment they thought they would need a much stronger field to levitate these objects with. I wish nature gave our fingers a magnetic field. I'm always dropping nuts and bolts when working on a car. Hey here is an idea magnetic gloves. Bert |

Hi oc I think that is very old fashion thinking that space is nothing.
We see the Casmir effect. These plates are pushed together because more energy(waves) can be outside compared with those that can fit between the plates. Again I repeat "space is more interesting than the stars" It is the force of gravity ,and the intrinsic energy of space that created all there is Bert |

From Painius:
..i remember back when long ago i read about how there is sooo much space between a nucleus and its accompanying electrons. And sooo much space between atoms, and how "ghostly" reality seems to be. Matter's 'ghostliness' is why Wolter called it the ephemeral "dustbunny" tagged onto the energy-dense Primary Reality. David Bohm recognized the same thing, calling the PR the 'Implicate Order' and the secondary, externalized universe the 'Explicate Order'. The ancient Vedic writers also recognized it, calling the material universe maya, meaning "illusion". But it's a very real illusion.g From Ody: If we try to picture electrons as little tops or other spinning macrocosmic objects we can easily be misled.... electron spin is quantized s=+/-1/2, either "up" or "down" but never in between. Without the aid of math, W gave a very straightforward conceptualization of electron spin (mentioned a few times previously). First, picture the (ground state) hydrogen atom as a modified sphere; it's somewhat oblate and 'dimpled in' at the poles. It's the most primal planform in nature, and common to all rotating systems it displays two hemispheres and a common equator rotating on a polar axis. But in addition to this circumferal spin, there is *axial* spin as the hemispheres roll out from the equator and back in thru the poles. Now strip the electron shell from the H atom's central proton and you have a 'rolling smoke ring' in space; it retains the axial spins of its two hemispheres, the 'N' hemisphere rolling up and back in thru the center, and the 'S' one rolling down and back in: these are the "up" and "down" components of the electron's spin in addition to its circumferal spin. Such a tripartite spin is possessed by no other particle. Now separate the two hemispheres, and what do you have? Two mirror-imaging 'rolling smoke rings' of the same circumferal but opposite *axial* spins: the electron-positron pair. What is called the "positron" is merely the second half the the normal electron. W stated that a true antielectron would have both its hemispheres intact. Other than this brief allusion to antimatter, he was mute on the subject of antimatter. If the above is correct, then PET scan tomography is not seeing true matter-antimatter anihilation but normal electron-'positron' interaction. The same would apply to those oppositely-curving electron-positron tracks observed in cloud chambers. oc |

From Bert:
Glad that one universal force(gravity) is being mentioned ,and all the other forces coming from this one force. When we finally unify the forces. this will be reality Well Bert, if gravity is merely one manifestation of the *flow* of the spatial medium, you gotta ask what is driving the flow(?). Whatever this First Cause is, it would be even more primal than gravity, and by implication, primal to the other forces in the Unified Field of Spatial Flows. Wolter called it the 'supra-cosmic overpressure' (to which Painius assigned the acronym SCO). The SCO is one of the imponderable 'givens' of the expanded model. Along with the pre-BB state, the 'roach motel' issue, and what lies at the 'ends' of eternity, it's one of the "flat Earth"" issues of the new model. The SCO may be criticized as 'ad hoc', but the mainstream's model is rife with ad hoc fixes like dark matter, dark energy, quintessence, extra dimensions etc. etc. So the 'One Force' driving all the flows (including gravity) would have to be the SCO. oc |

Hi Odysseus All matter particles have half spin. The half is,roughly
speaking,a quantum-mechanical measure how fast electrons ROTATE. Positron(electron evil twin) also have a half spin,but I see it rotating in the opposite direction. Interesting Odysseus all of the non-gravitational force carriers photons,weak gauge bosons,and gluons also possess an intrinsic spinning characteristic,and that turns out to be two times that of matter particles,for they all have spin-1 Then physicist having problem on the spin of the graviton(transmitter of force of gravity) came up with spin2,and that is twice the spin of photons,gluons,weak gauge bosons. Tricky stuff when a massless particle like the graviton has a spin at all. I have no problem with thinking spin as a top spinning(why should I?) It is rotational motion. In the sub-microscopic realm it has a quantum twist. I can live with that Bert |

He (Zinni) was just tryin' to p**s you off, you ol' coot! At least i haven't seen him yawn like a baboon, yet. g John got torked because i was trying to coax him into an explanation of why c is constant if there is 'no medium', when all he could do was post some old-hat web page. oc |

Hi oc the particle is the graviton it is the messenger particle. Like
the photon is the messenger particle for EM.Gravity's force gets stronger in the QM realm of the universe,and we give this stronger gravity a different name inside the nuclei of atoms and call the graviton a gluon particle. In the sub-nuclei realm we only give the graviton a structure feature. It is a tiny curled up string,a loop that is vibrating. See what I mean???? oc it is in the realm of particle science that my thinking gets weired enough to fit with QM. I have always felt this to be true. In astronomy we had the Hubble to show us macro reality. We have the electronic microscope and that hopefully could see a blurry bucky ball. In the sub-micro realm only our minds can probe there,and I like that. Bert PS all this gives me my next "what if" |
