Earth’s & Time Cycles

I am taking a break from my private research on cycles and put together this partial study. Feel free to point out cycles I missed. Photo links are just to better explain and compliment a subject.

Earth Time Cycles

A Day:

A day is one 360° rotation of the Earth on its own axis and a major cycle. Most living creatures on Earth adapted to this cycle. Some species for day, and others for night living. There are even species with a complete lifecycle of one day. A day is divided in 24 hours (12 in light and 12 in darkness). An hour is divided in 60 minutes and one minute in 60 seconds. The spin of the Earth is currently with a tilt of 23.45° to its rotation around the Sun. Therefore depending on your position on Earth the 12 hours of day and night period will change. As the spin of the Earth slows down over time more hours will be added to a day. It is estimated that Earth had a 7 hour day at birth around 4.6 billion years ago.

A Week:

A week is a 7 day cycle for timekeeping in our Gregorian calendar. Some ancient cultures used a week with different lengths in days with uncounted rest days to resynchronise, but the Romans also had a 7 day week prior to our Gregorian calendar. The seven days seem to come from our planets – Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn which are the sequence they rise in, as seen from Earth. Another theory is that it originates from a Synodic month where 4 x 7 = 28 and a ¼ of 29.53 = 7.3825

A Month and the Moon:

In the Gregorian month, also a human made cycle for timekeeping, the 12 most prominent constellations were used for the 12 months in the year, which originated from the Sumerians; 1) Capricornus - (Water Goat, January 20) 2) Aquarius - (Water Bearer, February 17) 3) Pisces - (Fishes, March 12) 4) Aries - (Ram, April 19) 5) Taurus - (Bull, May 15) 6) Gemini - (Twins, June 21) 7) Cancer - (Crab, July 21) 8) Leo - (Lion, August 11) 9) Virgo - (Maiden, September 17) 10) Libra - (Scales, October 1) 11) Scorpius - (Scorpion, November 24) 12) Sagittarius - (Archer, December 18).
The Synodic month is approximately 29.53 days and one complete Moon orbit around the Earth. Some cultures are still using it today instead of the Gregorian month. The tides caused by the Moon through its gravitational pull do have a direct influence on the life forms on Earth. Some life forms adapted to the tidal cycle and are dependent on it for survival. Statistics prove an increase in the crime rate over a three day period around full-moon and therefore suggest an influence on humans. “Personally I think it is due to the fact that people can see better in the dark, and just plan their activity around it.” We all know that the Moon does not disappear and it is only the shadow that Earth cause on its surface that makes the visible part change shape. As our bodies contain mostly water, some species do seem to be more affected by the Moon’s gravity. (Even two legged ones. He he)

A Year:

There are 365.2422 days in the year (the time it takes Earth to make one rotation around the Sun). The Sun’s most Northerly position is reached on the 22nd of December, and the Southerly position on the 21st of June. The Sun crosses the equator on March 20 at a point called the (Vernal Equinox), and on September 23 at the (Autumnal Equinox). The 23.45° tilt in Earth's axis of rotation gives us the seasons which are a mayor influence for life on Earth.

8-11 Years: (Sun Cycle)

One of the Sun’s cycles currently is around 8-11 years. The resonance between Earth and Venus relative to Jupiter matches the Sunspot cycle in years, not only for the last 400 years but also in 1000 years of historical record of "severe winters". As the Earth directed solar-flares (CME’s) have a direct influence on our weather, it’s clearly an important cycle. The sunspots and magnetic storms the Sun generate is a factor that can even cause Mini Ice Ages, depending on the length of consecutive weak periods. Our current solar cycle No. 24 had a very low solar maximum and an even lower one is predicted for cycle No. 25.

19 Years:

Is a Metonic cycle (named after the Greek astronomer Meton). There should be no effect for life on Earth as this is only the time period when 235 Synodic months are in synchronisation with our current Solar based (Gregorian) calendar.

25 - 30 Years: (Sun Cycle)

Ice core studies over the past several hundred years suggest a 25 - 30 year climatic cycle of global warming and cooling, with a slow rising trend from the Little Ice Age about 500 years ago. Current cooling should have started around 2005 ± 3-5 years to continue up to about 2030, and then renewed warming from about 2030 to about 2060 should occur. The Sun with its current below average solar peak seems to be right on song in this cycle. This seems to fit in the 8-11year Sun cycle with an additional influence.

Resonating Planet Cycles: (Sun Cycle)

Although an ongoing study and with the Jupiter/Saturn resonating cycle’s influence on the Sun already confirmed some years back there are still many breakthroughs to be made. As the data becomes available I personally would like to see the incorporation of the relation to the magnetic plane in these cycles, if not done already. If what I read about the little “Doomsday” comet Elnin and the effect it had because of its trajectory relative to our magnetic plane is correct, we surely need to.

±1 500 Years: (Sun Cycle)

Earth also experiences a proven 1 500-year warming/cooling cycle over the last million years. Multiple research data highlighted this previously unknown cycle. I cannot find information on where this cycle should fit in, therefore tried to look at our movement in the Orion Spur, where I hit a blank.

±4 000-6 000 Years:

A maybe, but no clear global cycle could be established. Although different type of large catastrophic events happened regularly to fit this model the past 50 000 years, some were local and no pattern could be proven on a global scale as per data from Ice core statistics. The uncertainty of this possible cycle seems to scare people into placing every possible catastrophic disaster they can think of on the net.

± 10 800 Years:

Earth is mostly an Ice-Age planet which could last up to several thousand years with warmer periods that seems to lasts on average around 10 800 years inside the Ice-Ages. We are currently 10 500 years into a warmer period. Our current orbital pattern match a previous similar pattern about 400 000 years ago when Ice-Core statistics prove the warm period then lasted for ±28 000 years. (Do not jump to conclusions)

±25 920 Years: (22 000 – 26 000)

The Earth got a wobble while spinning on its axis called precession. The cyclic variance in the position of the equinoxes in the Earth’s orbital path is mostly caused by the gravitational forces between the Sun, Moon, and Earth’s equatorial bulge and to a lesser extends the other planets. Because of this summer and winter will swap around from the Northern to the Southern hemisphere. Plato called this cycle the Great Year. This also controls the health of our oceans, as the upwelling of deep water caused by the wobble directly are responsible for the replenishment of nutrient essentials in the oceans. We reached a turning point in December 2012 in our relation to Polaris and Vega as the North Star.

±43 000 Years:

This is a cycle where the tilt in Earths axis varies between 22.1° and 24.5° with respect to the plane of revolution around the sun. Less of an angle than our current 23.45° means less seasonal differences between the Northern and Southern Hemispheres while a greater angle means greater seasonal differences. We are currently busy moving from 24.5° to 22.1°.

±100 000 Years:

It’s the time it takes the Earth’s orbit around the Sun to changes from a circle shape to more elliptic shape and back. The cycle produces approximately a three million miles variance. Currently Earth's orbital eccentricity is close to the minimum.

Milancovitch Cycle:

Milutin Milankovitch proved that when the different cycles (25 920; 43 000; 100 000) are in relation to each other at certain positions they combined their effects and are responsible for major changes to the earth's climate (even ice ages).

±400 000 Years:

Earth repeats a close to similar orbital pattern in our solar system every 400 000 years.

±800 000 + 1.2 Million Years:

No clear global cycle could be established without doubt; however a cycle is much debated and there seems to be enough grounds for further investigation. This look like some unknown factor is affecting our solar system differently every ±400 000 years.

24 Million Years:

The Vedic texts tell us that a ‘Day of Brahma’ consists of a 12 million years of light and 12 million years of night period. Life starts when Earth is reborn at the beginning of the day of light. All life seized to exist at the end of the day of light. The 12 million years of night is a dormant period without life. We are currently 5.5 million years into the day of light cycle.

25+ – 27 Million Years:

The difference between 25+ – 27 million years extinctions based upon geological findings do suggest a cycle around this time period exists for Earth in the last 500 million years. We are currently supposed to be 10 million years into this cycle therefore another 15+ million years to go before a possible reoccurrence. (No tin hats needed for this one)

60 - 140 Million Years: (Earth’s Internal Cycle)

Earth is alive and goes through notable natural changing processes every 60 to 140 million years without Humans or external influences. This is due to the “Below Earth Surface Activity” and a gradual process.

Milky Way Cycles:

We are oscillating (like a sign-wave or rotating around a larger system) ± every 33 million years through our galaxy’s plane while we rotate around its centre. We went through the plane 3 million years ago busy moving away, and about 30 million years more to go before we reach the plane again.
This is the only place where the 24 – 27 million year cycles could fit in and suggest a rotation around a larger system. It just doesn’t make sense if we were travelling like a sine wave to be constantly hitting a “Doomsday” spot on a cycle.

Our galaxy takes ± 50 million years to rotate 360°

Our solar system takes ± 225 million years to rotate around the galaxy centre.

Ad-hock Cycle:

Our Solar system seems to go through waves of asteroids/comets hitting our Sun. This in turn I believe could also affect the behaviour of the Sun. But because of the different trajectories it is difficult to pinpoint an exact time cycle as the periods vary extensively for object to reach the Sun. We seem to be heading or are already in a busy period. But we were hit and missed before. (Tin hats please)

Unknown Cycles:

We seem to know very little about our solar system’s movement in our local Orion Spur of the Milky Way. Therefore a possible Planet-X or binary Star and its cycle, although unlikely, cannot be ruled out. However people do too little research, get spooked, and then come up with doom porn answers.

Personal Conclusion:

If we are not hit by a large meteor or comet in the nearby future and the Sun behave itself, there do not seem to be an immediate danger to Earth from space. My climate thinking works as follows: Our most prominent cycle is the 100 000year eccentricity cycle and with a 3million mile difference it will be a lot colder when 3million miles further away irrespective of the atmosphere. Actually the atmosphere make-up will determine the level of the intensity. After the previous Yellowstone eruption 640 000years ago Earths atmosphere were also close to that of today and it didn’t prevent the following Ice-age. Earth will enter its next Ice-age with or without us. A tin hat for World War III or a jacket, you choose. Then again maybe we need both.

Thank you very much for all of your hard work. I truly enjoyed reading your post, and I now had much to ponder.

I find this to be fascinating. Considering what equipment with think was available when this was recorded. I'm honestly in awe every single time I use a calculator. Good job.

Wow, nicely written indeed mate! Alot of info I didn't even know.

S&F! These kind of threads make ATS worth visiting.

While most of the information was not new to me, it was presented quite well, and is quite informative. These are the sort of posts ATS needs more of. Excellent work, friend.
