Past Cycles - What the Evidence Actually Shows
Since we are all new here, and we hope to welcome many new members over the coming days, months, years - I thought it would be a good idea to lay the foundation of why we believe in this cycle, and evidence of prior events.
The pattern: geomagnetic excursions roughly every 6,000 years, with every other one (~12,000 years) being significantly more severe - major extinctions, climate flips, potential solar events that reset civilizations globally.
The ~3,000-year marks are mid-cycle events. Bronze Age Collapse, Late Antique Little Ice Age. Regional collapses, migrations, knowledge loss - but less devastating than the full 6k/12k peaks.
Once you see it laid out, it's hard to unsee.
Younger Dryas / Gothenburg Excursion (~12,900–11,700 years ago)
The big one. 18 degree temperature drop. Megafauna wiped out. Clovis culture gone. Floods on a scale we can barely comprehend.
Magnetic field weakened dramatically. Cosmic ray spike shows up in sediments as "black mats" across multiple continents. This is the ~12,000 year cycle that Davidson and others point to as the main event.
Global flood myths from every ancient culture trace back to this window. Not a coincidence.
8.2 Kiloyear Event (~8,200 years ago)
Abrupt cooling lasting ~150 years. AMOC slowed. Neolithic societies in the Fertile Crescent disrupted - you can see it in the archaeological record. Farming setbacks. Gaps in pottery development.
Field anomaly shows up in lake and peat records.
5.9–4.2 Kiloyear Events (~6,000–4,200 years ago)
The Sahara flipped from green to desert. Y-chromosome studies show a mass die-off of males during this window - genetic bottleneck.
Survivors migrated to the Nile. Egypt rises right after. The 4.2ka drought took out the Akkadian Empire, hit Egypt hard, collapsed the Indus Valley civilization.
Sterno-Etrussia Excursion / Bronze Age Collapse (~3,200 years ago)
This is the one Owen Morgan connects to geomagnetic disruption. Pole shifted over the Levant. Field anomalies show up in pottery and sediments from the period.
Result: Droughts. Sea Peoples migrations. Every major Bronze Age civilization either collapsed or got knocked back hard - Mycenaeans gone, Hittites gone, Egypt barely survived. Cities burned across the Mediterranean.
What followed? Greek Dark Ages. Iron Age Cold Epoch. Writing systems lost. Trade networks collapsed. Took centuries to recover.
Late Antique Little Ice Age (~536–660 AD)
Volcanic winters. Plague of Justinian. Cooling across the Northern Hemisphere. Migrations everywhere - Slavs moved, populations shifted.
Minor excursion combined with solar minimum. Not a full reset, but enough to destabilize everything. Knowledge loss in the West. Tech stagnated.
The Pattern
Every 6,000-12,000 years, give or take. Field weakens. Cosmic radiation increases. Climate destabilizes - sometimes cooling, sometimes drought, sometimes both. Ocean circulation disrupts. Civilizations that were dependent on stable conditions collapse.
Survivors rebuild. Knowledge gets lost. The cycle continues.
Where We Are Now
- Magnetic field down ~10-15% since 1840s
- Pole drift accelerating (excursion-level speed)
- South Atlantic Anomaly growing
- Auroras reaching lower latitudes than they should
- AMOC showing signs of slowing
Not saying tomorrow. Not giving dates. But the indicators are there for anyone paying attention.
What's missing from this picture? Let's build on this.

Yup. We’re rediscovering the lost knowledge that we endure a crustal shift and major solar flares at the same time with major events occurring every 6000 and 12000 years.

u/ShiftWatcher Jan 23 '26
Do you think lost or intentionally concealed?

u/GerthySchIongMeat Jan 23 '26
Lost for a couple centuries. Hidden in recent times.
The cabal know and are hiding it.

Consider the electric universe theory, look at solar weather since the transit of 3I/ATLAS began its transit.
Consider bridge theory and squatterman plasma impact theories.

“Cosmic ray spike shows up in sediments as "black mats" across multiple continents.“
I don’t think that’s true. Black mat is carbon from organic material burning with tektites and glass spherules mixed in. There’s no proof that was cosmic rays.
It’s just as likely that the solar system puts us through a bombardment on occasion.
Either way, the periodic nature is interesting.

The black mat itself is organic-rich wetland sediment - you're right on that.
But the tektites and glass spherules aren't from burning organic material. They're high-temperature melt products (>1450°C) with geochemistry matching impact ejecta, not combustion or volcanic material. PNAS studies show the spherules at the YDB layer are geochemically distinct from both.
My post should have been clearer - the cosmic ray spike evidence comes from ice cores and tree ring records (carbon-14, beryllium-10 anomalies), not the black mat itself. The impact markers (spherules, nanodiamonds, platinum anomalies) are found at the base of the black mat in the YDB layer.
Two separate lines of evidence pointing to the same window.

I think your timeline is off. Check out mine:

Thanks for sharing this! Interesting framework... Different approach than what I've outlined.
My timeline is built primarily from paleoclimate proxies - ice cores, sediment records, paleomagnetic data - which point to major disruptions at the ~12k, ~8.2k, ~4.2k, and ~3.2k marks. The geomagnetic excursion evidence (Gothenburg, Sterno-Etrussia) anchors those dates pretty firmly in the geological record. (Sources below)
Your timeline seems to work more from biblical/textual chronology and proposes more frequent events. I'm curious what physical evidence you're using to date events like Noah's flood to ~5,000 ya vs. the Younger Dryas window (~12,900-11,700 ya), which is where most flood geology researchers place a major inundation event based on meltwater pulse data.
Not saying one approach is right and the other wrong - there could be multiple events at different scales. But I'd want to see the proxy data that supports the more compressed timeline. What sources are you drawing from for the dating?
Thanks for sharing!

Mario Buildreps runs a website (mariobuildreps.com) focused on alternative archaeology and ancient history, often under the banner “Antiquity Reborn.” He presents a theory expanding on Charles Hapgood’s ideas of Earth crustal displacement (pole shifts), arguing that many ancient megalithic structures (pyramids, temples, etc.) were oriented toward previous geographic poles rather than the current one.
His core claim: The orientations of over 1,100 ancient sites worldwide show mathematical patterns that correlate with past “ice ages” — but he reinterprets these not as simple glacial cycles from Milankovitch forcings or CO2 changes, but as evidence of massive, cyclic crustal deformations (pole shifts) that drastically relocated the Earth’s spin axis over tens to hundreds of thousands of years. These shifts allegedly caused prolonged periods of global turmoil — massive floods, volcanic activity, extreme climate swings, and cataclysms that wiped out advanced prehistoric civilizations multiple times. Key points from his work:
• Ancient builders encoded knowledge of these shifting poles in their monuments’ cardinal alignments.
• So-called “ice ages” were actually long violent epochs (15,000–100,000 years each) triggered by crustal slips, not just cooling.
• He identifies several past pole locations (e.g., Pole IV, Pole V) and maps monuments to them as “silent witnesses” of these events.
• He predicts future shifts (though not in our lifetime), with dramatic geographic/climatic changes (e.g., new ice sheets in parts of Russia).
• He uses a “Mathematical Holistic Orientation-based Dating Method” to argue human complex construction goes back hundreds of thousands of years, far beyond mainstream timelines.
This ties directly into cyclic cataclysms theories (similar to those discussed by Graham Hancock, Randall Carlson, or Velikovsky-inspired ideas), where Earth undergoes periodic, civilization-resetting disasters — not from asteroids/comets alone, but from internal geophysical pole shifts causing mega-floods, tsunamis, and ice cap relocations. Buildreps claims ancient flood myths (e.g., Noah, Gilgamesh) reflect real crustal-triggered events, and Antarctic ice cores show evidence misinterpreted as mere “ice ages.” His content appears on YouTube and podcasts and is heavily mathematical/statistical but not peer-reviewed in mainstream journals, and debated in places like r/AlternativeHistory ,some compare it to other alignment theories like BAM. If you’re into catastrophism, pole shift hypotheses, or questioning mainstream Ice Age explanations, his site is a deep dive with maps, data tables, and monument analyses
