Finally, the contention of the solar system being the center of the expanding universe is something inferred from facts; any other center or any non-centes is due to a theory which tries to hide unlikely facts. I withdraw, as I did on other occasions, because taking a textbook test is not my style of living. Incorrectness is disagreement or non-compliance with with what is presumed to be true. (Of course, big bangers assume the the Doppler effect is a fact rather than an unproven theory. But dogmatists don't have the time to bother with such minutiae.) I'll sleep on my globally star-surrounded earth -- zenith, nadir, and the twilight zone. Good night. |

It is wrong. It is blatantly incorrect. It is not something inferred from the facts. What is inferred from the facts is that the expansion has no center. What is inferred from the facts is that the solar system is not the center of an expansion. You are contradicted by facts - not just inferences. No valid philosophical system can ignore the facts as you seem to insist on doing. |

In the balloon analogy, the folks on dot A will note that the other dots are receding, and might conclude that they are at the center of expansion. However, if they observe dot B and then perform some vector calculations to see how things would look from dot B (i.e. calculate the movement of all visible dots relative to B), they can note a universal expansion from dot B: or any other dot. The same applies to our Universe. Various galaxies are moving in various directions, but the overall trend is a movement AWAY from our Milky Way galaxy. If astronomers pick "distant galaxy X" and calculate the movement of all other galaxies relative to X, they note a similar overall trend of universal expansion from galaxy X. EVERY galaxy is apparently the center of the expansion. Because, in fact, NONE of them are. |

(Their procedure is logically fallacious, but I am not going to start teaching logic now.) Many of you do not know the difference between facts and theories. Idiotic theories are made everyday. Theories are in the books of physics, in the Bible, and in everydayday thinking, and most people believe in theories rather than facts -- for they themselves do not know what the facts imply. Case in point, I have taken two facts (light-waves have a velocity; perception occurs when and where light-waves strike the eye) and drawn logical consequences which happen to be contrary to certain solid beliefs [theories -- when the beliefs are put into words] people have and we all live by for practical purposes. By their conventional theory I was wrong, but they never found anything wrong with my explicitations. I am sure you mentally behave like them when I state that the sun you see (the visual luminous body in the sky) does not exist outside your eyes; the whole visual field which has the sky as the limit does not exist in front of your tangible eyes. (Join the crowd in the philosophy thread, "What is the star we are gazing at?") Since this Section is about gods and, appropriately, other self-contradictions, I am going to open a thread in the Science section about some Physics facts and theories, to show how certain theories about facts are actually groundless, mere imaginings, or how certain theories distort and even ignore facts. / Continuing in this threat may give the impression that I am rebeling against facts. ----- I'll sleep in my three-dimensional universe rather than a two-dimensional curved space universe without Lucifer above and the pit of hell at the opposite side. |

nor is your model a useful representation of spacetime. We were simply pointing out that your argument is based on fallacy. This seems like a valid criticism to me. Quote:
textbook contains theories, then it is YOU who don't know the difference between fact and theory. In physics, a theory requires rigorous testing and verification. The "theories" in the Bible are nothing but (un)educated guesses. Quote:
Because we found plenty wrong with it, if you'll go back and read. Take this, for instance: Quote:
and below" are meaningless. Any point on the balloon IS surrounded "globally" by other points on the balloon, if you confine movement to the surface. The really confusing part is when you say that you're dumping the balloon analogy but then go on to use it again. Except that now you're re-defining space as existing within the "thick skin" of another balloon, as you did here: Quote:
There are many shapes that spacetime could be, however, a thick hollow sphere is not one of them. We know this because of spacetime curvature, which we can measure very accurately. Spacetime could be saddle-shaped (hyperbolic), it could be a torus, or it could simply be infinite in all directions, none of which behave in the way your "thick balloon" model does. |
