Albrecht:
I originally started this question because I tried to show that
Einsteins SRT was wrong and then go on to propose some fixes. What I ran
into was the comment that I did not understand SRT. Conclusion to date
is that there apear to be many interpretations and fixes to what
Einstein said and how his theory has be reinterpreted and updated. It is
simply no good talking further unless one specifies which SRT one is
taking about.
My last E-mail to Graham included a quote from Einstein's original paper
which clearly stated that a clock moving around a closed circuit would
lose time. if I read the 1905 paper further the example Einstein uses is
to compare a clock on the equator with one on the pole claiming the
equilateral clock will run slower. This statement even shows that
Einstein had no qualms about including an accelerated reference frame.
Until the ground rules as to what interpretation of SRT one is talking
about I think it is not worth going on.
I would much rather continue the diussion along the Synchotron lines.
That is why I i said "New"
To respond to your comment empty space is flat it does not matter how
far away you are from local masses you are surrounded by masses and that
introduces symmetric forces that determine the gravitational potential,
speed of EM interactions, the speed of light , and clock rates.
Einsteins GRT has gamma dependent on the gravitatinal potential , and
obviously there are stars surrounding us so gravity determins the
property of intergalactiv space.
If you do not agree with this tell me why?
