Precession of the Equinoxes explanation

The foundations of timekeeping and where it comes into close proximity with the daily and orbital motions of the Earth (day/rotation and year/orbital circuit) is based on an astronomical event which happens at the end of the fourth 365 day cycle. In antiquity it was the first annual appearance of Sirius at dawn -

".. on account of the procession of the rising of Sirius by one day in the course of 4 years,.. therefore it shall be, that the year of 360 days and the 5 days added to their end, so one day shall be from this day after every 4 years added to the 5 epagomenae before the new year" Canopus Decree 238 BC

In contemporary and dynamical terms, as the Earth moves through space and around the Sun, certain stars close to the orbital plane of the Earth appear to move from the left side of the Sun (twilight) to the right side of the Sun (dawn) like ElNath,Castor and Pollux are seen to do -

Taking a wider perspective, the orbital motion of the Earth creates the apparent annual motion of the stars including the brightest star Sirius which the Egyptians spotted one dawn after being absent behind the glare of the Sun for over 2 months -

As full rotations (day/night cycles) are used to gauge the orbital period of the Earth, the Egyptians understood that an extra day keeps their festivals in close proximity to the Solstices and Equinoxes. In dynamical terms this represents close to 1461 rotations to 4 annual circuits or 365 1/4 rotations to one circuit
..
The calendar formats these 1461 rotations into 3 years of 365 rotations and 1 year of 366 rotations. The orbital drift corresponding to a 1/4 rotation is picked up the the full 24 hours of rotation on February 29th when the Earth returns very close to but not exactly to the same position it was on March 1st 4 years earlier.

The overall perspective is that there are 1461 rotations to 4 orbital circuits to a close proximity and the small additional difference is an added correction. This is only the beginning of the story because what the ancients seen as the Precession of the Equinoxes is really an extension of the original observation and the proportion between rotations and orbital circuits.

With the Precession of the Equinoxes now strictly an issue of the proportion of rotations to orbital circuits as an extension of the observation that Sirius drifts back into the glare of the Sun with each annual cycle of 365 days and rotations (hence it eventually skips a first appearance by one day at the end of the 4th annual cycle),it now leaves the new approach to solar system planetary climate open for technical discussion.

The term 'climate' is now dominated by socio-political issues that have a lot to do with lifestyles and nothing to do with climate . Planetary climate is not restricted to the Earth but to all planets hence the necessity of looking at the common traits which isolate a description of climate common for all planets.

We experience two simultaneous daylight/darkness cycles arising from separate rotational causes that come in under the heading of the seasons. In isolation the North/South poles experience the orbital component exclusively where a single daylight/darkness cycle is coincident with a year whereas all latitudes lower also experience a single day/night cycle due to daily rotation.

To even begin to discuss climate in a meaningful way requires the removal of the flawed axial precession in order to make way for the dual surface rotations where the poles themselves act like a window into the orbital behavior of the Earth -

Over the course of an annual orbit, the North/south poles will be seen to accomplish a rotation with respect to the Sun and to the circle of illumination.The next stage is introducing a climate spectrum between 0 degree and 90 degrees inclination and applying it individually to each planet.

The widest possible view of astronomical history going back over 5200 years and the intentional Solstice and Equinox alignments draws attention to the flawed notion of the dynamic behind the Precession of the Equinoxes insofar as the alignments still maintain the spectacle on the Dec/June Solstices or the March/Sept Equinoxes. Without the additional correction beyond the leap day correction, the orbital drift would be experienced within the calendar framework as a loss of those ancient Solstice and Equinox alignments.

The technical details as to why a false attribution to axial precession was posited existed in the way the geocentric astronomers formatted their observations including the observed motion of the Sun through the Zodiac. The RA/Dec proponents still try to describe orbital positions using the motion of the Sun through the Zodiac in celestial sphere terms of the 'first point of Aries'.

With just the slightest shift in perspective a substantially more productive and creative picture emerges By allowing for a relatively simple adjustment that stalls the Sun at center of the solar system and focusing on the observed effect as the Earth orbits our central star, the background field of stars play a different role -

Many thousands of years ago my astronomical ancestors chose to light up the darkness in a specific way and if readers take the time to go there they can experience the inside of that structure and enter an astronomical heritage at the same time -

This explains why the Tropical year is exactly the same length as
the Sidereal year in Geraldworld.

Here on Earth, there is a clear 20 minute difference, and the Equinoxes
move along the ecliptic about 1 degree every 72 years.

I think the small effect on the alignment at Newgrange is because
the solstice now occurs 1/4 orbit around from where it used to,
and the Earth is therefore at a slightly different distance from
the Sun (1% or something like that), leading to a four minute change.

This is a question of competence in a very technical sense so you are excused as are so many others here.

Again,a question of competence but I will expand on this without considering worthless gibberish about Equinoxes 'moving'.This is an issue strictly about the proportions of rotations to orbital circuits which show up as a drift in the annual position of Sirius and its first appearance far enough to the right side of the Sun where it shows up as a dawn appearance -

http://www.gautschy.ch/~rita/archast...liacsirius.JPG

The long term drift known as the Precession of the Equinoxes is a further refinement that is not attributable to presumed 'axial precession' but rather reflects that the number of rotations within an orbital circuit is not exactly 1461 rotations to 4 circuits nor exactly 365 1/4 rotations to one circuit. The ancient alignment such as Newgrange still reflect the relationship of the North/South poles to the central Sun and to the circle of illumination at the specific date of December 21st

Of course I inhabit a forum that follows a clockwork driven nightmare known as 'solar vs sidereal' time that has no basis in observation and its extension to a belief of 366 1/4 rotations per orbital circuit. With such abysmal reasoning it is really not possible to have a discussion.

The original heliocentric astronomers tried to account for the Precession of the Equinoxes using the antecedent geocentric framework which used the motion of the Sun through the constellations . The new perspective changes all that by concentrating on the observation where the stars drift from the left side of the Sun (twilight) to the right side of the Sun (dawn) as the Earth travels through space . When Sirius skips an appearance by one day/rotation after the fourth 365 day cycle it represents a fact that the proportion of rotations is not 365 rotations to one circuit but close to 365 1/4 rotations per circuit. The further refinement is then tied up with the Precession of the Equinoxes hence it is strictly a matter of a proportion of rotations to orbital circuits and Not an intrinsic 'axial precession' trait -

Nope.

The Gregorian calendar with leap years every 4, except every 100, except every 400, is a way to keep the Solstice at Dec 21st and the seasons from drifting relative to the calendar. This is all based on the tropical year of 365 days, 5 hours, 48 minutes, 45 seconds.

Sirius passing the Sun happens once every Sidereal year, 20 minutes longer than that, so that the position of Sirius in the sky on the Solstice drifts a little every year.

This is caused by precession.

In denying precession, you are not just denying Einstein, Newton or Ptolemy, you are arguing with Hipparchus and the Babylonians, extending your nuttiness back to the dawn of astronomy. Kudos!

The issue is highly technical, doesn't involve clocks and effects everything from the cause of the seasons, the proportion of rotations to an orbital circuit, defining climate for all planets in the solar system, the natural inequality in the noon cycle and many,many more topics.


With a clockwork driven nightmare out there it is difficult to find the right type of people who can discuss the matter in a reasonable way and untangle timekeeping from the dynamics so as to create a streamlined research platform.

It all depends on the proof for the Earth's orbital motion around the Sun and the annual motion of the stars from left (twilight) to right(dawn appearance) due to the orbital motion of the Earth through space -

When you can handle the proportions of rotations to orbital circuits and what the extra rotation represents in terms of that proportion then get back to me but not before then. The Precession of the Equinoxes is an extension of the small orbital drift as the Earth doesn't turn in exactly 365 1/4 times per circuit.

Can you understand this much ?.

If you were right, the equinox would not precess, and the First Point of Aries, named by Hipparchus, would still be in Aries, and not in Pisces heading for Aquarius.

But you are quite wrong.

Telling people to grow up generally alienates them however it still requires intelligent people to bypass the annual or long term ideologies of a geocentric framework where the Sun was seen to move through the Zodiac and then the small additional drift known as the Precession of the Equinoxes.

The shift to the 21st century perspective where the Earth moves around the Sun and causes the background stars to disappear behind the central Sun's glare as they move from a twilight appearance to a dawn appearance is the bedrock of the proportion of rotations to orbital circuits as the crucial event where Sirius was seen to skip an appearance by one day/rotation generates the proportion of 365 1/4 rotations per circuit .

So put away your clocks for a while and join an astronomical tradition which did spot that Sirius skipped an appearance by one day after the fourth 365 day cycle. When you can answer why that happens you can then engage in a discussion on the further refinement which shows up as the Precession of the Equinoxes.

I look forward to reading your explanation of where Precession of the Equinoxes comes from, if, as you say, attributing it to axial precession is an error.
