From my thread “Does the Moon Rotate?”, I determined that an axis with a point continually facing in the same direction is connected to some thing external to its orbit (exp. your arm could be this external thing holding a pencil as an axle), as opposed to being connected to the center of orbit. In other words, if a point on Earth's axis continually faces the same direction, regardless of its location in orbit, it can't be attached to the sun by gravity.
Physical sciences deal with real physical objects; metaphysical, or the mind; with concepts. Truth is achieved when mental concepts match physical reality. The invisible things of this world are clearly seen, being understood by the things that are made.
An axis is an imaginary axle used to determine truth. As such, an axis must operate like a real axle to match reality. A real axle is always physically attached to some thing: center of orbit or some thing external. If attached to the center of orbit, a point on the axle is constantly facing the direction of motion and is perpendicular to the center of orbit. A point on an object mounted on this axis rotating at a constant velocity, will return to the same position with every rotation: noon is ~noon every ~24 hours of rotation. Also, if a point on the mounted object is continually aligned with a point on an orbiting axle, the object is rotating about the center of orbit; not on its axle. Exp... The nose of a carousal horse mounted on the pole through its back always faces the direction of motion and is perpendicular to the center axle. The horse is rotating about the center axle; not about the pole through its back.
If the orbiting axle is attached to some thing external, and the mounted object is continually facing the center of orbit, it indeed is rotating about the axle, which I call orbital rotation. This velocity of orbital rotation must be independently added to the velocity of axial rotation (point on an object realigning with a point on an axle: one complete rotation). If Earth's axis continually faces the same direction throughout its orbit as proposed by Kepler, and Earth makes one complete rotation about its axis in ~24 hours, noon would be constantly advancing by the value of orbital rotation. However, since noon is ~noon every day, Earth acts as though its axis is attached to its center of orbit (sun). You can't have it both ways. Through observation and experimentation we know that noon is ~noon every ~24 hours, and therefore, we can not assume that Earth's axis continually faces the same direction per Kepler.
Earth rotates 360 degrees on its axis in ~24 hours = one solar day. Earth elliptically orbits the sun 360 degrees in 365.25 days = One Year. In other words, Earth rotates 365.25 times from Spring Equinox to Equinox. 360 degrees / 365.25 days = .9856 degrees. Earth makes one ~24 hour rotation every .9856 degree of its 360 degree orbit.
Conversely, 365.25 days / 360 degrees = 1.0145833 days. Earth rotates 1.0145833 times for every degree of its 360 degree orbit. Orbital rotation would be .0145833 X 24 hrs X 60 min = 20.99 minutes. In other words, if Earth's axis is continually facing the same direction regardless of its location in orbit as proposed by Kepler, noon should occur ~21 minutes later every day. That is not what we experience.
Earth's axis attached to the sun, whether tilted or not, can not account for the seasons. The seasons only work with a tilted axis continually pointing in the same direction. Since neither scenario, axis attached to the sun or to some external thing, matchs reality, an alternative to consensus science must be sought.
