<br>
This is already a very bad idea of starting such a thing. If I invent<br>
an example of obvious nonsense, which no scientist will even start to<br>
read, I use "Einstien's logical errors in Relativity". Your title<br>
is already close to this. Trust me: There are no logical errors in<br>
relativity.<br>
<br>
Then, what you provide as evidence, even if much better, does not fit<br>
into that "promise". Essentially, you describe, as an error, that one<br>
should not restrict oneself to SR effects but also has to take into<br>
account GR. Fine. That was the point of inventing GR. And certainly<br>
not an "error in modern physics", but only of some physicists who<br>
thought that GR effects will be negligible, so that they have not<br>
computed them. (Or they were too stupid to compute them, whatever.)<br>
<br>
A logical error is on your side: you make an approximate computation<br>
(yes, 18 digits is quite precise, but it is only an approximation,<br>
even 1800 digits would be, from a logical point of view) and name the<br>
0 result a "precise mathematical proof". It is, of course, not.<br>
<br>
> General Relativity has exactly the opposite time-rate effect from what all Physicists believe to be true.<br>
<br>
False. Too lazy to search, but even wiki level physics would tell you<br>
that SR and gravity effects for, say, GPS satellites act in different<br>
directions, thus, will at least partially cancel each other.<br>
<br>

<br>
GR is necessary because gravity plays a role. Acceleration can be<br>
handled with SR too, no necessity for GR.<br>
<br>
> They always exactly cancel each other's net effects out for us!<br>
<br>
No. This is simply false. For the surface of a planet, say, idealized<br>
as an ideal liquid, the time dilation on the whole surface may be,<br>
indeed, the same everywhere on the surface. But the clock showings<br>
are already different at different heights, and for modern clocks this<br>
effect is visible already for a few meters or so (don't know the<br>
actual value) difference in height.<br>
<br>

<br>
No. Such claims are based on general formulas, in GR (which has to be<br>
used) inertial frames play no role at all, they are not even<br>
well-defined.<br>
