[Physics] Real Time

[carmam at tiscali.co.uk]

Thanks for your input Carl. Your points are certainly valid, but as far as I am concerned your objection is not. The reason that it is not valid is that we take it as read (I do anyway), that the time dilation is from the point of view of the observer - which in this case and in most cases on Earth is the man at the North Pole. If that statement is in error, then why bother mentioning him at all? As for ignoring GR, it is a convenience which makes life simpler and can be used later if required.

Your group certainly has many creative ideas 
regarding Einstein and Relativity.  Unfortunately, nearly all of the 
assumptions are not correct.
 
The Earth provides wonderful evidence for us, 
moostly because we have really accurate data rwegarding its (Equatorial) 
diameter and its precise sidereal rotation period.
 
Specifically regarding your 
discussions:
 
Someone standing at the North Pole does not have 
"velocity" nor "acceleration" and so the Lorentz-Fitzgerald (beta) factor is 
exactly ONE.  (velocity is ZERO).
 
Fine.  The more interesting situation is for a 
man standing at the Equator.  He DOES have a precisely known (v) there 
and so it is easy to calculate the Time Dilation Factor to be 0.999 999 999 998 796 
560
 
And so everyone ASSUMES that he would EXPERIENCE 
Time Dilation there.  There are TWO major errors in those 
assumptions.  (a) HE would not experience any Relativity issues, and only 
the OBSERVER at the North Pole (motionless) would SEE any such effects.  
Nearly everyone is wrong about this error.
 
(b) the other error in assumptions is due to 
everyone IGNORING General Relativity, which happens to have its own time-rate 
effect.  It is called the Equivalency Principle.  (Surprisingly) this 
effect happens to be the OPPOSITE of Special Relativity's Time Dilation.  
Thaht calculation (onn Earth) is also easy and precise to  do, and it is 
1.000 000 000 001 203 
440
 
Oddly enough, since BOTH Relativity time-rate 
effects must constantly apply to our guy att the Equator, we must MULTIPLY these 
two effects to find the ACTUAL Relativity time-rate effect for that guy at the 
Equator.  That simple product is EXACTLY ONE.
 
In other words, the ACTUAL effect due to BOTH forms 
of Relativity exactly cancel each other out.  There is NO DIFFERENCE in 
time rate between the guy at the North Pole nd anyone at the Equator, or 
anywhere else on Earth.
 
Only when someone is in a Non-Inertial Reat Frame, 
that is, accelerating, will an OBSERVER see any time-rate effects.
