Actually, the second is defined as a certain exact number of oscillations of a cesium atom in the same reference frame as the observer. The same problem still exists. The cesium atom didn't exist before the first super nova. How can the time be calculated between the Big Bang and the first super nova if cesium didn't exist? There are other entropic processes that can be calibrated against the cesium. -- Dave Oldridge+ ICQ 1800667 |

Seems to me all we can see is back to the point where things are moving away from our relative position at less than the speed of light. Did you know that the red shift is quantitized, i.e. not continuous, even within the same galaxy? -- 73, Cecil http://www.w5dxp.com |

Did you know that the red shift is quantitized, i.e. not continuous, even within the same galaxy? So some people are saying. And we still get to see parts of the universe that were close to us post- inflation, though the universe is really too opaque at that distance to see the really early stuff. But we're nearing the threshold where cesium would be rare or non-existent. In short, we're SEEING some of those early supernovae that made it in the first place. Several cosmologists think that's the cause of the gamma-ray bursts we're experiencing. -- Dave Oldridge+ ICQ 1800667 |

All parts of any given galaxy are not moving toward or away from us at the same speed, unless the galaxy is perfectly perpendicular to us. Is your red-shift issue about the red shift itself, or about the magnitude of the shift? And if "variable seconds" is the culprit, how are blue shifted stars accommodated in your model? - 73 de Mike KB3EIA - |

True, but consider that the red shift frequencies are discontinuous, i.e. quantized. Is your red-shift issue about the red shift itself, or about the magnitude of the shift? And if "variable seconds" is the culprit, how are blue shifted stars accommodated in your model? My issue is that red-shifts are not necessarily 100% Doppler effects. -- 73, Cecil http://www.w5dxp.com |

And if "variable seconds" is the culprit, how are blue shifted stars accommodated in your model? My issue is that red-shifts are not necessarily 100% Doppler effects. Of course there is gravitational redshift too, but I don't think that is what you are referring to. I think you are trying to say that time is variable (forgive if I err) This means that the speed of light is also variable if only by relation to that variable time element Doppler effect is readily observable at audio and RF wavelengths. It is widely accepted that the effect continues at light wavelengths. Any effects that alter Doppler at light wavelengths should also be noticeable at to wavelengths. I have not heard of any such, have you? This then says that we are not in the "fastest time" zone, because there are celestial bodies that are blue shifting toward us, or perhaps not,they are just in a different "time zone"? ;^) BTW, I erred in my perpendicular statement above. I forgot about transverse Doppler shift that we would indeed have in a galaxy at right angles. - 73 de Mike KB3EIA - |

There are other entropic processes that can be calibrated against the cesium. Hi Dave, You have been snookered into answering a complaint manufactured (as usual) from the misapplication of relationships. The resonance of Cesium is not a function of time. Time is not a function of Cesium's resonance (the incorrect correlation drawn, to which you are responding). There is no dependency between the two. It is our dependency in our usage of one to measure the other. The sophism above is much like saying sound did not exist before someone was close enough to hear the falling tree. The excitation of gas molecules we call sound existed long before the appearance of the first amoeba, much less apes in falling trees. Both sound and time are phenomenological terms for simple and rational physical processes that exist without dependence on us. 73's Richard Clark, KB7QHC |
