Planetary collision that formed the Moon made life possible on Earth

Click For Summary

Discussion Overview

The discussion centers on the hypothesis that the planetary collision which formed the Moon contributed to the conditions necessary for life on Earth by introducing excess Carbon, Nitrogen, and Sulfur into the Earth's crust. Participants explore the implications of this event on the chemical composition of Earth and its potential role in the development of life.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants reference a claim that the excess Carbon, Nitrogen, and Sulfur in Earth's crust resulted from the planetary collision that formed the Moon, noting an unexpected Carbon/Nitrogen ratio of 40/1.
  • Others mention the extensive study involving approximately 1 billion scenarios to understand the conditions in the solar system, suggesting that the collision had a significant role in shaping Earth.
  • One participant draws a parallel to Velikovsky's theories, implying alternative explanations for planetary interactions.
  • Another participant emphasizes the computational feasibility of running a billion scenarios quickly with modern supercomputers and clever algorithms.
  • There is a mention of Velikovsky's ideas contrasting with traditional gravitational theories, suggesting a divergence in understanding planetary dynamics.

Areas of Agreement / Disagreement

Participants express a range of views on the implications of the Moon's formation for life on Earth, with some supporting the hypothesis while others introduce alternative theories. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

The discussion reflects varying assumptions about the role of the Moon's formation in Earth's chemical evolution and the methods used to study these scenarios, including the reliance on computational models and the interpretation of historical events.

Finding the answer involved varying the starting conditions, running approximately 1 billion scenarios and comparing them against the known conditions in the solar system today.
That is some kind of study - a billion scenarios.
I have often thought that the moon - er rather the collision that resulted in the Earth - has had a role to play.
 
Shades of Velikovsky ?

A billion scenarios can be calculated with a supercomputer within a couple of days at most ! A clever algorithm can reduce that calculating time by orders of magnitude !

Shades of Velikovsky would invoke electrostatic forces rather than plain old Keplerian orbital evolution. He didn't "believe" in gravity.
