No, Seto. A second is a second. There are not multiple definitions for a second. See: Relativistic Effects on Satellite Clocks http://relativity.livingreviews.org/open?pubNo=lrr-2003-1&page=node5.html Hey Seto, what is the value that Model Mechanics predicts for observed time dilation of a clock in a orbit (eccentricity = 0) at an altitude of 212 km above MSL?

Hey idiot I already told you that the absolute frame have the following special properties: 1. The speed of light is isotropic c. 2. a clock in the absolute frame is the fastest running clock in the universe. 3. a meter stick in the absolute frame is the longest meter stick in the universe. Einstein claimed these special p4roperties of the absolute frame for every ineertial observer and that's why the laws of physics for every inertial frame are the same.

That is wrong, Seto. Those are not the properties of an absolute frame. You have simply assembled a list of properties and attributed them to the string of words "absolute rest frame", but this is not what "absolute rest frame" means to physicists. You are making the same mistake as someone who looks at the properties of a cat, which is a mammal, and then concludes that the following are properties of mammals: 1. Mammals have fur. 2. Mammals have four legs. 3. Mammals give live birth to their young. When in fact, NONE of those properties are properties of mammals, though they are properties of a cat. You cannot *deduce* properties of an absolute reference frame. You have to simply ask physicists what the properties of an absolute reference frame are, as that term is used in science. That is, you have to ASK what the definition of the term is, and accept that definition as it is given to you. It does absolutely no good to reject a definition of a term as used in physics and substitute your own. It just makes you a crank when you do that. > Einstein claimed these special p4roperties of the absolute frame for > every ineertial observer and that's why the laws of physics for every > inertial frame are the same. > > Ken Seto > > - Hide quoted text - > > > > > - Show quoted text - > > |
