<DIV><FONT color=#000080 size=2 face=Arial>Under Relativity circular motion is
NOT absolute - I have most definitely 'questioned that' in my last several
emails. The whole point of my recent missives is to make it clear that
Relativity allows a person undergoing circular motion to consider themselves at
rest - and that view is as valid as any other, under Relativity.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>That's why GR then has to come into
it. Because even whilst considering themselves to be at rest, that person
will experience a force - and GR allows them to regard that force as a
gravitational effect (and considers that as valid a view as any
other).</FONT></DIV>

<DIV><FONT color=#000080 size=2 face=Arial>The whole point of GR was to extend

Relativity.</FONT></DIV>

Paradox</DIV>

<DIV class=WordSection1>
<P class=MsoNormal>Hi All<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>We have discussed the “twin paradox” and many have said
that there is no paradox. But using SRT alone this is not strictly true.
The postulate that “all motion is relative” is an arbitrary and so far
experimentally unsupported part of SRT. This postulate alone causes a
paradox.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>But there is another way to consider these
issues<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>We have established that circular motion is absolute, and
no one has questioned that, because we have experimentally been able to verify
that is the case.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Now let us take that circular motion toward the limit, and
continue to enlarge the radius of that motion. Still, no matter how
large the radius, circular motion is absolute. At what point, at how large a
radius, would you say that the laws of motion change from absolute to
relative?<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>The fact is, the laws of motion do not change from absolute
to relative, even if the radius is so large that we cannot measure the
curvature. All motion is not relative.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
