QUICK SUMMARY

This document examines Complete Meteor & Asteroid Impact Catalog: Earth's Full Bombardment History, a topic within the Cataclysms and Chronology research area. Key areas of investigation include Theia Giant Impact (~4.51 Ga), Late Heavy Bombardment (4.1–3.8 Ga), Barberton Greenstone Belt Impacts (~3.47–3.26 Ga). The analysis spans topics including * meteor, asteroid, comet, impact, crater. Notable findings include: 2020 study (Nature Communications*) by Erickson et al. precisely dated to 2,229 Ma. The document presents evidence organized across multiple tiers — from peer-reviewed and verified claims to more speculative interpretations — with cross-references to related topics throughout the knowledge base.

PURPOSE

This document is a comprehensive catalog of every known, suspected, and mythologically recorded impact event in Earth's history — from the planet-forming Theia collision to modern fireballs caught on dashcam. It also catalogs every significant near-miss event and known future close approaches. This expands E_1_02 with exhaustive detail and additional events.

6.3 Tall el-Hammam — The Sodom Connection (2021, RETRACTED)

[RETRACTED SOURCE] The Bunch et al. 2021 Scientific Reports paper proposing this airburst was retracted by the journal following findings of image manipulation in the original figures (retraction tracked via Crossref + Retraction Watch; retracted April 24, 2025 for errors in analyses, data, and methods; retraction notice DOI: 10.1038/s41598-025-99265-5 (supersedes prior notice DOI: 10.1038/s41598-022-06266-9)). The Tall el-Hammam airburst hypothesis is therefore no longer part of the peer-reviewed cosmic-impact literature. The entry below is preserved for historical context — the underlying archaeological site is real, but the cosmic-impact interpretation should be treated as a withdrawn claim until and unless re-published in a peer-reviewed venue.

15. KEY TAKEAWAYS

  1. Earth has been struck by objects capable of ending civilization multiple times — only one (Chicxulub) killed off the dinosaurs because the others predated complex life.
  2. The human era has seen multiple significant impacts — Kaali, Campo del Cielo, Chelyabinsk — and near-misses that missed by hours (4581 Asclepius, 1989)
  3. Chelyabinsk was completely undetected before impact — a 20 m object at 500 kt energy
  4. 2023 BU passed closer than satellites — only 3,600 km from Earth's surface.
  5. Apophis will pass inside geostationary satellite orbits in 2029 — visible to the naked eye.
