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. 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 Yes, time is about as much related to the vibration of a cesium atom as it is to the pendulum im my grandfather clock. Except we now define its unit in terms of the oscillations of a cesium atom. And sure, it's relative. But, in the same reference frame as the observer, the cesium clock is sufficient. -- Dave Oldridge+ ICQ 1800667 |

Let me rephrase that to be more accurate, "our time" is about as related to the real functioning of RF as is a fairy tale told to children which serves as a "satisfactory" explanation to them on some abstract functioning of reality. Although some type of movement seems to be involved in RF (at least at this present time), it has little to do with our observations of movement of other objects and phenomenon which is unrelated to RF. However, it would be difficult to deny a real and accurate "universal time frame" (UTF) of some sort. It is even quite possible our understanding of RF, antennas, etc. with greatly expand when we finally discover this UTF and are able to devise ways to further expand our manipulations of our use of RF ... time is movement (but the movement of our earth and atoms are defined by the UTF, NOT the opposite!), if you view time as anything else, you are most likely in error ...
