Existence of collisional trajectories of Mercury, Mars and Venus with the Earth
This page documents how this source is reused across Claim by Claim. A source can support, challenge, qualify or contextualize different claims; appearing here does not imply endorsement of every linked proposition.
Evidence roles describe what this source helps establish inside each Investigation. They are local to that use, not permanent labels attached to the publication itself.
Long-horizon future instability models and eclipse-based rotation since 720 BCE do not directly measure or validate a Mars–Earth approach in the eighth–seventh centuries BCE.
Per-source study access and uncertainty documented in B09 R02–R03; not independent direct verification of the overarching historical event.
Challenges
Modern simulations can produce future Mars-Earth collision trajectories, but only in rare long-term chaotic solutions after billions of years and with broad destabilization.
Laskar and Gastineau modeled 2,501 possible futures over five billion years, not an ancient comet-like Venus trajectory.
Per-source study access and uncertainty documented in B09 R02–R03; not independent direct verification of the overarching historical event.
Challenges
Numerical integrations do permit rare terrestrial-planet instabilities, but on billion-year chaotic timescales rather than a recently settled historical orbit.
Modern N-body work shows terrestrial-planet collision trajectories as rare outcomes of long-term chaotic evolution, with major destabilization rather than a quiet recent encounter followed by today's orbits.
