Allen,
I think you you and I are in absolute agreement on every single detail of the
"dual axis proof" except one, which of course, makes the difference, and is
what I've been trying to get accross to you, which you have answered by
basically telling me to look at a globe and/or sweeping it away without any
detail other than to repeat things that I already agree with you on. Please
consider this carefully and prayerfully and with patience. I would prefer to be
wrong, but am afraid I am not. I have spent allot of time looking at a globe,
drawing globes, determining what a camera would record with different motions
and axis's and lengths of axis's, etc.... As have you.
That detail in question being: how much does the earth rotate in 24 hours?
You have said: 1 full 360 degree rotation, which would allow a camera
(regardless of orientation) to record star trails around the yearly axis, since
the camera would rotate about the yearly axis.... I say: 1 full rotation plus a
hair more (something like ~360.9863 degrees), which would allow a camera to
record only a repeat of the nightly cirlce, since that is the axis the camera
has rotated along.
If the earth returns to it's exact location and position and orientation
every 365 days while traveling 360 degrees around the sun, then it moves
0.9863 degrees around the sun per day. So a complete day, midnight to midnight
is 360.9863 degrees. To check this, lets look at the position in 182 days.
Midnight on day 182 would be facing practically 180 degrees away from midnight
on day 1. Your formula would have 182 days times 360 degrees per day = a whole
integer with no remainder.... therefore your midnight would be facing the exact
same direction as 182 days earlier, except that we are now on the opposite side
of the the sun....so you have midnight facing the sun..... midnight does not
happen in the daytime. My formula would be 182 days times 360.9863 degrees per
day = a whole integer with a remainder of ~180 degrees... therefore my midnight
would be facing directly away from the sun, allowing midnight to happen when
it's dark.
The only way to record a yearly star trail about the annual axis is to have
the camera rotate about the annual axis.... and there is no way to do this....
The only path that moves perpendicular to the annual axis is the 23.56 path,
but the camera will not rotate. The 24hour path rotates, but only around the
nightly axis.
If this still doesn't convice you, then please.....please, don't repeat the
things we agree on, which is everything, except what the camera revolves around
on the 24hour path.

I think your drawing has captured it all, exactly. The green circles could
also be described as the camera location at 4 different points of the year
(following the 24hour path), while trying to record a yearly circle, and if you
look at it that way, you'll see why no annual circle can be recorded....you've
moved around the same axis as the nightly.... therfeore you'll have only
recorded the nightly. The red lines show where you would like for your camera
to be, in order to record an annual circle (because the path is perpendicular
to the axis), except that those points only exist along a 23hour 56minute path,
and as shown in a drawing that Allen did, there is no rotation of the camera on
those paths, so no annual circle can be recorded there either. This is why I
have dropped out from those supporting this proof. Since the mechanics involved
make it impossible to record anything other than a nightly trail, the lack of a
yearly trail in recordings is not proof of anything.

Dear All,
This is my attempt to explain more graphically Neville's last drawing showing
the two axes of rotation.
1 The green circles are a fixed spot on the world shown in four different
positions traversing the ecliptic path. The NEP is perpendicular to the grey
ecliptic plane. This illustrates the world's 24 hour rotation. I have tried to
take great care to get the geometry correct within the limitations of my
drawing software.
2 The green circles also represent the world traversing its annual orbit
about the NCP. These are shown as red ellipses. The NEP, according to my
drawing geometry, also traverses the NCP.
Since there are two rotations happening simultaneously but at very different
velocities the illustration can only show an NCP rotation (red ellipses)
extrapolated for a whole year. I value comments by all as to whether I have
understood the problem or not. I do have a series of 12 illustrations, similar
to the one below, showing the position of the ecliptic plane every 30 degrees
about the NCP.
