A newly published preliminary study by Italian researchers developed a Relative Erosion Method (REM) analyzing the The Great Pyramid of Giza. The method compares two types of erosion on the same rock type in the same location: one with a known date and one from an unknown period. By applying this to exposed surfaces of the pyramid, the study attempts to estimate construction age through statistical analysis of erosion patterns. This dating methodology is worth watching. 🧱🔬
Relative erosion method dates Great Pyramid to 25,000 years

Key facts
- Italian engineer Alberto Denini developed Relative Erosion Method (REM) analysis of the Great Pyramid's base
- The 675-year-old earthquake loosened limestone casing stones, exposing underlying bedrock to weathering
- Denini analyzed 11 points around the pyramid base comparing known 675-year erosion to older exposed surfaces
- Statistical analysis yielded a mean date of approximately 25,000 years for the pyramid's construction
- Some dates reached close to 40,000 years
- This is within one thousand years of one traditional great year (precessional cycle)
