I'll make this simple for you.


I'll do the same and cut your verbiage.

.. the rotation of the
Earth is determined by a clock as 24 hours per 360 degrees.


We can test your hypothesis this weekend as "daylight
savings" ends: when everyone "put's the clock back",
if you are right the resulting tidal wave will inundate
us here in Europe.

.. the Earth does
not roll around the Sun ...


Still trying to take us back to Ptolemy Gerald?

The sidereal value of 23 hours 56 min is based on the axial rotation
of the Earth in 24 hours through 360 degrees,the pace of all clocks is
set by this rotation


Wrong, the 'pace of all clocks' is set equal to the
_combined_ effect of the rotation of the Earth and its
orbit around the Sun. 23 hours 56 min for its rotation
and the other 4 min comes from the 1 degree it has moved
along its orbit round the Sun.


Accept the sidereal value of 23 hours 56 min as the 'true ' rotation
of the Earth and Kepler's second law goes out the window and takes
Newton's gravitational laws with it.

Go ahead George,make the comparison and you will find you cannot have
your cozy 1 degree daily displacement.

Obviously you still cannot answer the question I set
you, "What time is it in figure 2?", but then you
never were much good with clocks:

Good luck.


Ha,ha,somebody fudged the data and tried to squeeze the Equation of
Time into the 24 hour astronomical day when the Equation of Time
defines the astronomical day by using the Sun as a reference for the
motions of the Earth,both axial rotation and orbital motion.Unless you
did'nt know the meridian alignment at noon when the Earth rotates to
face the Sun directly registers an unequal pace for each axial
rotation,the natural unequal day in other words.

The EoT equalises the distance covered in the Earth's orbital motion
as a reflection of Kepler's second law,the days are not unequal just
because the Earth has an elliptical orbit but also the variation in
the motion through that elliptical orbit.

It is a simple choice George,accept the sidereal value and its cozy 1
degree daily displacement using the Sun and Earth and say goodbye to
centuries of human achievement,you get your relativistic Earth rolling
around 'warped space' but manage to demolish Newton's gravitational
laws based on Kepler's planetary laws in the process.

This is not a taunt but you cannot make these graphics fit,one has to
be valid and the other can only be considered rubbish,your choice.

Kepler's planetary laws are approximations. They are based on two-body
motions and are derived from a curve fit, not an underlying dynamic.
Newton derived the inverse square law from Kepler's work, but his
inverse square law is not right either.

The earth rotates 4 degrees per minute, completing 360
degrees in 1436 minutes (23:56) and 361 degrees in
1440 minutes (24:00). I don't know about you, but I
would call 360 degrees a "true rotation".

I'm dying to hear why a change in the earth's rotation
rate would throw Kepler's second law or Newton's gravitational
law out the window, especially since neither deals with
rotation rate.

Look at that picture. Imagine a planet moving from X to Y. Imagine
a planet is at X and a certain point on the equator is pointed
at the sun. Now imagine the planet moves to Y while the planet
rotates 360 degrees. Notice that the point on the equator
is now no longer facing the sun.


http://www.astro.virginia.edu/class/...olarday-FB.gif


That illustrates exactly this point. Notice the little
man has rotated through 360 degrees. He has the same
orientation in both pictures. But in the second picture
it is no longer noon.


Obviously you still cannot answer the question I set
you, "What time is it in figure 2?", but then you
never were much good with clocks:


It is clearly 4 minutes before noon. In 4 minutes the planet
will rotate another degree counterclockwise, bringing the
sun directly overhead of the little man.

The day is set by the stars ,,not the sun.
Its your mistake.
