Don't get ahead of me or yourself snip If all matter expands, the way gases do, this in itself, provides the basis for a model of gravitation to use for thought experiments and possibly for finding unexplored experiments to compare with other models. Do you honestly believe that two "balls" of gas of different sizes would both "expand" and double their size in the same amount of time? If so, then are are wrong. If not, then you are basing your model on a false premise. You are essentially lying to yourself and everyone else when you say "if all matter expands, the way gasses do" because your model requires matter to expand in a way that gasses do not. Stephen |

$ 'GR cannon-ball "feelings"'; By jOE Fischer

Because of most materials, gas, liquid and solid being composed of not only all the elements, changing phase at different temperatures, but also being mixtures and numerous chemical compositions, any propositions concerning all materials becomes very complicated. That is why I try to restrict the discussion to one specific chemical element in the beginning, but everybody wants to get to orbits and other complicated processes right off the bat. It would be nice if you could argue specific points, instead of generalities. OK - electrons are known to be point particles and to gravitationally interact. Explain to me how a point can expand? Bill I am not sure they do, but I also do not think that electrons have ever been tested to be attracting each other gravitationally. I am sure they appear to "fall" like everything else, and they surely add to the mass of an object they are a part of, but I don't know of a specific experiment that suggests they "gravitationally interact", whatever that means. The very reason that everything can "fall" the same, is because nothing "falls" because of gravity. If anybody knows of any claim I make like this that is not essentially the same as im General Relativity, please let me know. Joe Fischer |

Simple well defined math (its called differential calculus) allows us to take the concept of the position of a body and its displacement and define velocity and acceleration. A definition cannot be wrong. It can be inconsistent or useless by not corresponding to anything important in the physical world. But it cannot be wrong. BY DEFINITION a definition cannot be WRONG. |

If they are components of a system of mechanics, then that model defines them. Those terms alone are defined by Newtonian mechanics, but in other models there can be other, more specific terms. Velocity and acceleration are defined as vector quantities as is position displacement. Position relative to what? Referenced to what? In Newtonian mechanics, the surface of the Earth is assumed to correspond to a rigid rectilinear coordinate system, the one described by Euclid, and LET and SR also need this same type of coordinate system. Simple well defined math (its called differential calculus) allows us to take the concept of the position of a body and its displacement and define velocity and acceleration. Provided the mechanics has defined the coordinate system. I don't know what stuck clueless or falling space henry uses for a coordinate system, but personally I don't see any way to define a coordinate system without using material objects as references, it is certain space will not provide any references, and a lot of gravitational physics only uses one large object and one very small test object. A definition cannot be wrong. It can be inconsistent or useless by not corresponding to anything important in the physical world. But it cannot be wrong. BY DEFINITION a definition cannot be WRONG. Is this an English class? There exists a number of different types of velocity and acceleration, all named differently, and they are not just different names for the same process. It may be that the next theory or model that comes along will have to define a certain kind of acceleration and velocity, and perhaps even more than one of each. Have you followed this thread, or are you acquainted with the premise of the subtitle material I was trying to present before responders tried to get ahead of me? If there were such a thing as Divergent Matter, then all the existing definitions would have to be examined. The quarter mile drag strip would be getting longer, doubling in length about every ten minutes. But the meter stick would also double in length every ten minutes, and the second would double in length every ten minutes (longer pendulums have a longer period). On the drag strip, all this would not have much of an effect, but there may be situations where large effects would occur. Sometimes I do things a little bit different, as far as I know, parabolas have always been drawn by ploting points generated by an equation. I don't do that, but I have drawn and machined parabolas with instruments I built. Trying to document the Divergent Matter model is very difficult, because it is very different. I don't think the math would be as difficult as that of General Relativity, but it would be very different, with all differently defined terms. But frankly, over the last 35 years that I have been writing about it, I have not found a single person who approached it in a mature and open minded way. It seems like every person has an agenda, or a fixation, or are rigidly disciplined, or lack the ability to understand even simple physical things. Knowing the mechanism of gravity may not mean much for surface dwellers, it might help a lot in astrophysics and cosmology. And new definitions will be needed. Joe Fischer |

Dear Mr. fkasner:
Please stop trying to fight insanity. He who battles insanity has it transferred to themself once the battle is over. The purpose of Usenet is for a bunch of narcissistic fraternity brats to use up all of America's precious computer memory (isomorphic to fossil fuel depletion) and bring down the General System. No meaningful dialectic is intended. Have a nice day. |

Do you honestly believe that two "balls" of gas of different sizes would both "expand" and double their size in the same amount of time? I do, but why not ask a physicist, this is something that can be tested. You really need to learn some physics. Do you know why gasses expand? You claim to be looking for mechanisms. Do you understand the mechanism behind the expansion of gasses? If gasses behaved they way you claimed, the would spontaneously and continuously increase in temperature. This does not happen in the real world. snip If there were any progress at all being made in finding some other mechanism for gravity, I would be delighted, positive results are the goal, but if no progress is being made, all models remain to be studied. You apparently have no real interest in understanding gravity as you apparently have no interest in learning anything about physics. Try figuring out how gasses behave in the real world and why. It is not that hard. Stephen |
