Some hypothesis but could it be true? http://www.captaincynic.com/thread/66271/excerp_the_solar_system.htm
Earth's orbit varies over million of years. It stretches and shrinks. This accounts for 7 ice ages.
Earth tilts on its axis 23 1/2 degrees. This tilt causes seasons. The northern and southern hemispheres alternately lean into and away from the sun. When it is summer in the United States, it is winter in Australia.
Hmm . . . This last statement seems to default my hypothesis? If the electro magnetic axis of the earth were pointed toward a distant reference (focal) point then would not the elliptical orbit of the earth cause the poles to align with that focal point?
Film exposed through a telescope are rotated to stay fixed upon a point (star) otherwise the spin of the earth (24 hour) would produce a vague smear of light.
That at the earth's furthest point of orbit (elliptical) and it's closes point would point toward the same reference or focal point? Assuming that the earth orbital rotation is separate or distinct from the focal point => that the earth's rotation (orbit) does not include the focal point such as the rotation of a volume.
On several occassions I have made apologies for my inability to communicate effectively. Returning to this page, certainly reinforces my lack of communication skills! Be that as it may is that this mindless dripple disrupted my sleep most of the night . . . it took me that long to come to understand (at least in part) what it was that I wasn't comprehending?
A simple principle which had to be related in order for me to make the distinction between rotation & spin?
