Younger-Dryas Period–Mystery Solved?


Starting in about 13,000 (BCE) the Earth experienced three major climatic catastrophes–one after another; i.e. (Bölling-Allerød, Younger-Dryas and Pre-boreal warming periods). They are described here as catastrophic because that 1-2-3 punch is said to have annihilated a significant percentage of life on Earth.

  • The Bölling-Allerød interstadial was a sudden, intense, climatic warming (~12° C; ~21° F) period which caused dramatic melting of large Ice Age ice sheets that covered Canada and the northern U.S., all of Scandinavia, and much of northern Europe and Russia. Sea level that had been 120 m (~400 ft) lower than present rose quickly and submerged large areas that had been dry land during the Ice Age. This warming occurred abruptly in only a few years (Steffensen et al., 2008). This warm period ran from c. 12,800 to c. 10,900 (BCE). It ended abruptly with the onset of the Younger Dryas.
  • The Younger-Dryas was a cold period that reduced temperatures back to near-glacial levels within a decade. It began about 10,900 (BCE) when global temperatures plunged sharply (~8°C; ~14° F), sparking a 1200-year period of glacial re-advance. Its end came abruptly with the onset of Pre-boreal warming about 9,700 (BCE).
  • Pre-boreal warming began about 9,700 (BCE) when, almost overnight, global temperatures rose parabolically (~12° C; ~21° F), marking the end of the Younger Dryas cold period and the end of the Pleistocene Ice Age. The peak rise in temperatures was reached about 9,500 (BCE) 

There has been an abundance of speculation as to the cause of these events (even a book or two) but no one has offered an explanation that ties all three events together. This article argues that all three events may have a physical cause and, if so, their timing may be predictable. The supposition is presented in a logical, well laid-out, manner and is supplemented with ample charts and diagrams. The analysis begins by identifying the underlying motion that is believed to cause the precession of the equinoxes and then introduces a series of harmonic structures that may provide an answer for the abrupt shifts in temperatures occurring between 13,000- and 9,500 BCE (video).

The precession of the equinoxes is the observable phenomena of the rotation of the heavens around the Earth–a cycle that is said to span a period of (approximately) 25,920 years (Platonic year).

The cause of the precession of the equinoxes remains a hotly debated topic. At the heart of the debate is the source of the underlying motion that cause the equinoxes to precess. I believe that motion is a cycle of 80-years and that apsidal precession is the phenomena that produces the 25,920-year precession cycle.

Apsidal or orbital precession is the gradual rotation of the line joining the apsides of an elliptic orbit which are the points of its closest and farthest approach. For the 80-year cycle, the closest point to its center of rotation is “A” (79.753846153-years). The farthest point is “B” (80.24767802-years). Therefore, a mean orbital period of 80-years.

Apsidal Motion


Apsidal motion is like the winding of a clock; the spring is wound by synodic interaction of its two components. Therefore, the spring winds 162.5 turns in one direction (high-potential) and then, unwinds for another 161.5 turns in the other direction (low-potential). The combined synodic motion of 324 turns or orbits is the foot print of the Platonic-year; i.e. (25,920-years), a period commonly associated with precession.

Ancient Mayan Creation Cycles–The Connection

The ancient Maya called themselves the children of the Sun with the Moon being the mother and the Sun the father. They are widely acknowledged as gifted astronomers and were without equal when it came to calendar making. But, rather than using just one calendar, as we do today, the Maya used several calendars—simultaneously—which were all magically integrated into one grand timekeeping system.


Ancient Mayan Integrated Timekeeping System

Their timekeeping system was mechanical in nature and consisted of four intermeshing gears (like what you would find in a pocket watch) and, as the primary calendar is advanced by one day, the others updated themselves proportionately. They were not so much interested in time–their primary focus was timing.

For each of the calendars they built a mathematical model in the form of a stone pyramid which was impervious to the passing of time and able to withstand the cataclysmic forces of nature… the only way of insuring the long-term survival of their sacred technologies.

Mayan cycles are all harmonic derivative’s of the Pleiades cycle which consists of 26,000-tuns (360-day years). Interestingly, the 26,000-tun cycle is also the approximate period of the precession of the equinoxes. Therefore, from the Pleiadean perspective, the Sun would appear to make one full revolution around Alcyone (the central star of the Pleiades group) every 26,000-tuns or 9,360,000-days.

The following illustration shows the two primary intervals of time that makeup the Pleiades cycle. 1. 26,000 /4 = 6,500 Mayan years and 2. 26,000 /5 = 5,200 Mayan years or the 4th and 5th harmonics. The 6,500 year periods define the galactic alignment. The 5,200 year periods are said to be cycles of creation. Naturally, creation implies an ending.


On close inspection of the 26,000 year cycle you’ll see that the cycle oscillates back and forth between 26,000 and 25,840 years with a mean of 25,920 Mayan years (below).


Therefore, the simulation values used in our mathematical model are 6,480 and 5,184 instead of 6,500 and 5,200. Before a simulation of the interactions between the two cycles can be run, however, a start date or end date for the cycles is required. And, there’s only one date that Mayan scholars generally agree on and that is -3112 or -3113 BCE. So, the date chosen for the model was -3/21/3112 BCE. By simply adding 5,184 the calculated end date is 2,072 AD.

The chart below shows the simulated interactions of vibrational frequency  patterns created by the two cycles over a period of 16,000-years–ending in 2072 AD. For context, the results of the calculations are overlaid with Ice-Core temperature data for the same period of time. The apparent correlations between the two cycles and abrupt changes in temperature, such as occurred during the Bölling-Allerød, Younger-Dryas and Pre-boreal periods are striking.

As you can see in the close-up below, the chart leaves little room for doubt that the two cycles are somehow linked to abrupt climate shifts (red dotted lines).

Apparent Correlations

Temperature turning-points appear to correlate with wave amplitudes of +100% or -100% or 0% and, when the waves cross each other’s path. The data has not been manipulated in any way. The cycle components are simply responding to a common ending date of 2072 AD. The sinewave calculations simply work backwards from that point.

How did they know?


Solving the mystery of the ancient 360-day calendar


It appears that ancient 360-day calendars may have been used globally until about the eighth century BCE., a leading internet source, has cataloged eleven different cultures that may have used them at one time. This article is an investigation into the possible source and purpose of such a calendar.

The literature indicates that 360-day calendars were used for at least two-thousand years and, in most cases, were probably an integral part of 365-day calendar systems–using intercalary periods. The question is how did all eleven of these cultures come with the same basic calendar of 360-days with twelve 30-day months which they could modify to efficiently track the seasons.

If the objective was just about tracking season, a 364-day calendar would have been much easier to live with (13-months of 28-days with each month having exactly four 7-day weeks). Add a holiday at the end of the year and you’re done. And, if your birthday, for example, was Tuesday, the 2-day of March, it would fall on Tuesday, the 2-day of March every year thereafter.

It seems unlikely that the original 360-day calendar had anything to do with tracking seasons as it would become out of sync by a full month in just 5-years and would have, almost certainly, been discarded. But, they were not discarded which would suggest that they served another purpose.

Then, there’s still the puzzling question of how the 360-day calendars were propagated. Physical barriers such as mountains, deserts and oceans that separate Mesopotamia, Mesoamerica and China would seem to preclude the merging of proprietary technologies. So, what happened?

The answer may be found in ancient Sumeria.

According to the Ancient History Encyclopedia the ancient Sumerians emerged as a culture around 5,000 BCE and lasted until about 1,750 BCE. Historically, what we call civilization, likely began in the ancient city of Eridu. As the oldest known civilization, it seemed reasonable to assume they were the first culture to embrace a 360-day calendar and so, they became the initial focus of this investigation.

The literature explained how their history and accomplishments had been lost in time–even their name. Their secrets remained buried in the deserts of Iraq until the 19th century AD, when French and British archaeologists finally stumbled upon Sumerian artifacts while hunting for evidence of the ancient Assyrians. Since then, archaeologists have recovered some 500,000 clay tablets, the majority of which are yet to be translated.


By 3,100 BC the Sumerians had already become a highly advanced and sophisticated civilization. They had a writing system (cuneiform script) and a library containing hundreds of thousands of historical documents. They also had a governmental structure and legal system and were building bridges, dams, aqueducts and irrigation systems. They are also said to have invented the wheel and plow. Mathematically, it appears that their skills were well beyond what historians had imagined. The evidence suggest that they could perform advance arithmetic calculations and may have been the initiators of the science that would later become known as astronomy. They are also said to have developed the Sexagesimal structure for measuring time–using sixty-second minutes and sixty-minute hours (like we use today) and created a measure of distance based of miles, feet and inches. It also appears that they may have mastered geometry and were able to calculate areas of rectangles, triangles and trapezoids and some believe that sophisticated geometrical calculations were being used to track the movement of planets.


Unraveling the puzzle

Over the next several years an original concept slowly began to evolve.

The Sumerians divided the 360-day year into 30 day months, the day into twelve 2-hour periods, and these periods into thirty 4-minute intervals. With 1440-minutes in a day, 4-minutes is equivalent to 1/360th of a day. That indicated that they not only divided the Earth’s orbit into intervals of 360, they also divided Earth’s rotation into intervals of 360.

Interestingly, 4-minutes X 360 = 1440-minutes (day) and 1440-minutes X 360-days = 518,400-minutes (year). When 518,400-minutes is multiplied again by 360 the result is 186,624,000 and, curiously, that number happens to be a match for a value listed in the Cannon of ancient numbers as the Earth’s orbital diameter (93,312,000-mile radius X 2). Being uneasy about the implications, I decided to let it set.

A couple of years later I was trying to make sense out of the Sexagesimal system and came up with an idea. I decided to deconstruct the 186,624,000 number that I had previously came up with by the Sexagesimal time structure of a day. First, I divided 186,624,000-miles by 360-days which resulted in 518,400-miles per-day. That figure was then divided by 24-hours which resulted in 21,600-miles per-hour. Next, 21,600-miles was divided by 60-minutes which resulted in 360-miles per-minute. Finally, the 360-miles per-minute was divided by 60-seconds which resulted in 6-miles per-second or 6-hertz (The very same as the frequency for the Earth that was insisted upon by Nicola Tesla).


To summarize what i’d learned up to that point;

  1. The cube of 360 X 4 equals 186,624,000-miles (theoretical diameter of Earth’s orbit).
  2. 186,624,000-miles is the product of a Sexagesimal year.

At this point and time, I was convinced that the Sumerians were the legitimate source of the 360-day calendar, but I was troubled by the size of discrepancy between 186,624,000-miles, the proposed diameter of Earth’s orbit, and the currently accepted value. So, once again I decided to let it set.

Several years later I came across a paper written by researcher Arnold D. Enge which got my attention. Mr. Enge had discovered that the ancient Mayan’s primary calculation for Earth’s orbit was 365.625 days rather than the 365.2422 days that is the commonly attributed. Their name for this period was “uinalhaab” or one-year. The “uinalhaab” turned out to be the missing piece of my puzzle.

It now appeared that ancient astronomers may have viewed the Earth and Moon as a system or binary pair. What follows are a couple of facts in support that supposition.

Sol-Lunar Year

A lunar-year of 354.375-days is consistent with the present-day Islamic calendar which has been in use since ancient times and the 365.625-day “uinalhaab” has now been verified by other qualified authorities. The mean of those two is precisely 360-days.


To verify the validity of the binary supposition I decided to utilize the time-distance formula that I had learned earlier (4-minutes X 360 X 360 = 518,400). But, instead of multiplying 518,400 by 360 as I had done earlier, I multiplied that figure instead by the number of days in the lunar year and the number of days in the uinalhaab.


The results as listed in the above table show that the closest approach to the Sun (semi-minor axis) is 91,854,000 miles and that the farthest approach (semi-major axis) is 94,770,000-miles. The sum of those two equal 186,624,000-miles (major axis). The preciseness of these calculations (using known values from independent sources) was enough to convince me that an Earth-Moon binary is a reasonable hypothesis.

Synodic implications

Apsidal motion of the binary pair produces twelve 30-day mini-cycles or months attributable to the Earth and thirteen 27.69230769-day mini-cycles or lunar months attributable to the Moon. The mean apsidal motion, however, is 28.8-days (see table).


The following diagram shows the outer perimeter of 365.625 days and the inner perimeter of 354.375 days with the mean solunar orbit of 360-days. The oscillating line illustrates the apsidal motion of 27.69230769 days.



How significant are these so-called mini-cycles or months? 

You be the judge.

  • 27.6923076923 X 260 = 7,200-days or 20 solunar years (Mayan Katun)
  • 30 X 360 = = 10,800-days or 30-solunar years (Saturn orbital period)

Both are significant periods and when the solunar values are converted to the 365.242 format, it’s obvious that the values reflect the Jupiter-Saturn synodic and the mean Saturn orbital period of 25.56943615 years.

Another important consideration is the synodic implication of the 354.375- and 365.625 day periods, which is 23,400-days or 65-Solunar years (below).


Why is that important?

The answer: harmonic resonance

  • Earth-Mars synodic period is 780-days X 30 = 23,400
  • Earth-Venus synodic period is 585-days X 40 = 23,400
  • Uinalhaab orbital: 365.625-days X 364 = 23,400
  • Solunar orbital: 360 X 65-days = 23,400
  • Lunar orbital: 354.5454: 66 X 360 = 23,400
  • Venus orbital: 225 X 104 = 23,400
  • Mercury orbital: 87.96992481 X 266 = 23,400

The Grand Synodic
