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 |

The two are entirely different. No, they are both earth-centric concepts invented by man. That makes them alike, not different. -- 73, Cecil http://www.w5dxp.com |

You'd have to be able to demonstrate that relativistic effects single out particular units of measurement to the exclusion of others without having an effect on the observed phenomena and all within the same reference frame before being able to substantiate any claim that the result of a particular measurement is arbitrary. Can you demonstrate that? Relativistic effects certainly single out measurements of time - also length in the direction of velocity. It has been demonstrated numerous times that the velocity of a clock affects the length of its second. What is the velocity of the cesium clock on Earth? -- 73, Cecil http://www.w5dxp.com |
