All objects in the universe are in motion and so there is no one object we can say is stationary wrt the universe. All particles of water are in motion in a cloud, but to the extent that the boundaries of the cloud are definable in some way, it's possible to discern the relative speed of any object to the cloud itself. Yeah, that makes more sence I think. It does? How so? It has nothing to do wrt the universe, which is what I was referring to. What you think makes more sense does not contradict what I've said because it is not the same situation. It is only possible to discern the relative speed of an object wrt another object. We cannot discern the speed of an object wrt the universe but only wrt to another object. Even those objects that are stationary wrt each other are moving wrt the universe, although they are moving at the same speed and in the same direction. Both statements should make the same amount of sense to you if you understood them equally well. Maybe I didn't understand you're statement very well, it sounded like you were saying that nothing can be stationary wrt the universe. |

Yeah, that makes more sence I think. Physics is about forces and what we can measure... So any distant event is conditioned by this: http://hyperphysics.phy-astr.gsu.edu...orces/isq.html In between the doctrines of religion and science, stand the philosophical perspective of metaphysical cosmology. This ancient field of study seeks to draw logical conclusions about the nature of the universe, man, god and/or their connections based on the extension of some set of presumed facts borrowed from religion and/or observation. One example is the cosmological argument which is an argument for the existence of God based primarily on the point of view that the mere existence of a universe demands a creator. As a finer distinction between religion and philosophy, esoteric cosmology is distinguished from religion in its more sophisticated construction and reliance on intellectual understanding rather than faith, and from philosophy in its emphasis on techniques of psycho-spiritual transformation. http://en.wikipedia.org/wiki/Cosmology That is not to say the discussion is not a part of physics. Only to point out that a "reference frame" can plot a point three universes down the street and around the corner till the dog barks where Mr. Jones's old cow used to be tied up. )Sue... |

CFran, nothing we can observe has ever been found to be stationary wrt
the universe. In fact, physicists love to argue that there is no center to the universe, as the BB "happened" everywhere at once creating a universe where everything visible in it is in motion and so we cannot locate any stationary object in space from which to measure how fast we are moving in the universe. The BBT claims that space came out of the BB and so that too is expanding still. I tried to explain that there are two qualifying phrases that must be included when talking about stationary objects. It is important to know that in reality nothing can be said to be stationary in the universe. Only when compared to another object can we say something is stationary. So when we say that something is stationary, we intuitively know that we mean it is stationary wrt another object because nothing can ever be stationary wrt the universe. I hope that helps. |

We cannot discern the speed of an object wrt the universe but only wrt to another object. Why is that? Saying so doesn't make it so. Do you believe that there is an infinite amount of matter in the universe? If so, do you agree that at any given instant, there is a center of mass of the amalgam of all of the matter in the universe? If so, why is that not analogous to the location and speed of a cloud? Even those objects that are stationary wrt each other are moving wrt the universe, although they are moving at the same speed and in the same direction. Both statements should make the same amount of sense to you if you understood them equally well. |

"TomGee" wrote in message oups.com... CFran, nothing we can observe has ever been found to be stationary wrt the universe. That's because we cannot observe the boundaries of the universe. But does that mean that the universe in infinately large? In fact, physicists love to argue that there is no center to the universe, as the BB "happened" everywhere at once creating a universe where everything visible in it is in motion and so we cannot locate any stationary object in space from which to measure how fast we are moving in the universe. The BBT claims that space came out of the BB and so that too is expanding still. Space is the absence of matter and energy. Naturally, the absence of something is infinite. However, if you're claiming that space itself is expanding, this means that it has a boundary, and that means that the geometrical ,center of that boundary would be calculable if the boundary could be observed. I tried to explain that there are two qualifying phrases that must be included when talking about stationary objects. It is important to know that in reality nothing can be said to be stationary in the universe. Only when compared to another object can we say something is stationary.

If you like a graphical and geometrical approach, and if you have Mathematica, you may wish to try out the SpacetimeGeometry notebook at my web site. http://home.earthlink.net/~djmp/Mathematica.html Your notebook appears to require a package called DrawGraphics, for which you appear to charge $50. You've already excluded the majority of your audience just by requiring Mathematica, and of those remaining, I can't believe that anyone would pay $50 to see your diagrams without even an example of what they look like. I think that the effort you put into this notebook will largely be wasted unless you at least provide a minimal free version of DrawGraphics to use with it, or better yet convert the presentation to TeX or HTML. -- Ben |
