Continental Drift

The continents move. When you rewind them, the ancient sites line up more precisely — peaking at 20 million years ago.

Using pyGPlates with the Müller et al. 2022 rotation model, we reconstructed the positions of 68 ancient sites at multiple geological time periods. The results show the network was positioned for an older version of Earth — not the one we inhabit today.

The Earth Is Not Static

In Plain English

The continents sit on massive slabs of rock called tectonic plates, which float on the semi-molten mantle beneath. These plates move at roughly 2 centimetres per year — the same rate your fingernails grow. Over a million years that's 20 kilometres. Over 20 million years it's 400 kilometres. Over 50 million years it's a thousand kilometres. Using GPS satellites we can measure this movement with millimetre precision right now, and using geological software we can project those movements backwards through time to calculate where any point on Earth was located at any date in the past — or future.

Notice that at 20 million years ago — the peak period — the sites form more precise geometric patterns.

Why 20 Million Years Ago?

Triangle Precision Score — Lower Is More Equilateral
Score of 0.0024 at 20Ma — 4.5× more precise than today.

The Triangle That Proves It

At 20 million years ago, three sites form a near-perfect equilateral triangle: Nabta Playa (Egypt), Nan Madol (Micronesia), and Tenochtitlan (Mexico).

The three sides measure: 12,395 km / 12,424 km / 12,425 km. A difference of just 30km across 12,400km — precision of 0.24%. These sites are on three completely separate tectonic plates moving in different directions. The probability of this occurring at a specific date by chance is extraordinarily small.

What 20 Million Years Ago Looked Like

During the Miocene epoch, the Earth's magnetic field was unusually stable. The Drake Passage between South America and Antarctica had recently opened, establishing the circumpolar current. Africa was moving northeast, Europe was largely tropical, and the Mediterranean was beginning to close. The continental configuration at this date produced the most geometrically precise relationships between ancient site locations of any period we tested — past or future.

Where Do the Sites Go in the Future?

In Plain English

We also projected site positions forward in time — which nobody had done before. The results were unexpected: the alignment precision doesn't simply degrade going forward. It improves again, peaking at 100 million years in the future when 17 sites align on one great circle — the highest count of any period, past or future. And at 10 million years in the future, three sites form the most precise triangle in the entire dataset — more precise even than the 20 million year past result.

What the Forward Projection Means

The sites don't just look backwards to a better-aligned past. They maintain geometric significance across an enormous sweep of time in both directions. This suggests the sites were positioned at locations that are geometrically special not for one epoch but across hundreds of millions of years. Whatever positioned these sites understood not just where the plates were — but where they were going.

10 Ma Future — East African Rift

The East African Rift Valley completes its split. Somalia, Ethiopia and Kenya become a separate island continent. A new ocean forms. This shifts the African plate sites significantly — yet the alignment between Jericho, Nan Madol and Caral reaches its most precise triangle of any period tested.

50 Ma Future — Mediterranean Closes

Africa fully merges with Europe. The Alps become dramatically taller. The Mediterranean Sea disappears. Australia collides with Southeast Asia. Egyptian sites end up in what is now Scandinavia. Stonehenge approaches the North Pole.

250 Ma Future — Pangaea Proxima

All continents merge into the next supercontinent. Ancient sites currently spread across the globe are brought physically close together again. Alignment precision likely peaks again — a second geometric optimum, 250 million years from now.

What Was Dry Land When the Sites Were Built?

In Plain English

At 10,500 BC — the date when all four major sites achieve perfect star alignment — sea levels were approximately 60 to 70 metres lower than today. The last Ice Age was ending, the ice sheets were melting, and sea levels were rising rapidly. This means enormous areas of land now underwater were above sea level and potentially inhabited. Our analysis only includes currently above-water sites. If any sites existed on what is now the sea floor, we are missing part of the network.

What Was Above Water

  • The entire Persian Gulf — a fertile river valley, not a sea
  • Doggerland — the North Sea between Britain and Europe, dry land
  • Sundaland — Indonesia, Malaysia, Borneo joined to mainland Asia
  • The Sunda Shelf — shallow sea now, dry land then
  • Much of the continental shelf around India
  • Extended coastal plains around all continents
  • The Gulf of Cambay in India — where underwater structures have been found

The Underwater Sites

Several documented underwater structures match our predicted locations for network nodes. The Yonaguni monument off Japan was above sea level at 10,500 BC. The Dwarka ruins off India's coast were above sea level. The Gulf of Cambay structures in India have been carbon dated to approximately 9,500 BC — above sea level at that date.

Our alignment analysis was run including nine known or suspected underwater site locations at their 10,500 BC positions — above sea level coordinates. Adding these sites increased the total alignment count and strengthened the convergence signal toward the Antarctic and Pacific nodes.
