Late Heavy Bombardment Cause

TNRTB Archive - Retained for reference information

Planetary scientists have strengthened the evidence that Earth’s core is fine-tuned for the support of advanced life and also for an extremely rapid origin of life. They discovered the means by which the late heavy bombardment could be heavy enough to restructure Earth’s core. They found that the era during which inner solar system planets grew through the accretion of asteroids ended with the remaining inner solar system asteroids left on highly inclined orbits. These leftover asteroids caused a very heavy bombardment of the inner solar system planets, with a decay time of 60 million years. The high inclinations imply extreme impact velocities, which imply that the late heavy bombardment indeed was energetic enough to restructure Earth’s core so that Earth could later support advanced life. The 60-million-year decay time shatters the naturalistic origin-of-life hypothesis in that it establishes that there was virtually no time for life’s origin on Earth (late heavy bombardment peak = 3.85 billion years ago; first positive evidence for life on Earth = 3.80 billion years ago).
