Hey idiot how does he do that?? He doesn't measure....he predicts using the SR equation. >But they know that each clock is running at the same > rate .. differences in clock sync make the measurement of a given moving > clock slower Hey idiot...Clocks in relative motion are running at different rates. Clocks in relative motion cannot be in sync without redefining the definition for a clock second in one of the relative frame. The GPS clock is made to be in sync with the ground clock by having its clock second redefined to have 4.446 more periods of Cs 133 radiation than the ground clcok second. > > >> >4.

So your > statements is self-contradictory. It is an exclusive property.....SR hijacked it and claimed it to be the property of all inertial frame.

Sure....SR adopts the exclusive properties of the preferred frame to derive its math. LET also uses the preferred frame to derive its math. That's why SR and LET have the same math.

The rest is all dreamwork upon SR you try to play dice with guys who change the dice as the play go on. There is no such creature like inertial frames. there is only objects with properties within space. They think that time is what clocks measures, you know better time is the absolute invariant rate that goes by during an event. When every observer ***calculate/get*** the same length of passed period during event, you do deal with time, Otherwise you treat time in the same way the early relativists tried to treat mass as relative bullshit, relative mass was not even a unit. Now adays we do have a proper mass unit, unfortunatly we have bullshit dimensional meter and time units (they are none quantifiable) no proper reference exist. This will of course affect the definition of measured velocity see the hogwash definition of lightspeed as isotropic invariant c. But i do like your attempts to define a proper time, it is the only way to go. Maybe i do read about IRT one day. JT
