Influencias astron\'omicas sobre la evoluci\'on geol\'ogica y biol\'ogica de la Tierra (parte I)

TL;DR

This monograph explores how astronomical events like meteorite impacts influence Earth's geological and biological evolution, including new explanations for phenomena such as the Tunguska event.

Contribution

It introduces a new model for atmospheric explosions and offers novel explanations for observed phenomena related to cosmic impacts.

Findings

Calculation of atmospheric bubble evolution from cosmic explosions

New explanation for Tunguska event phenomena

Insights into meteorite and asteroid effects on Earth

Abstract

This monograph presents a study of the nature and origin of meteorites, asteroids and comets; and of the consequences of encounters of these cosmic objects with the Earth. The purpose of this monograph is mainly of divulgation for non-specialists, even though we have not avoided some elementary technical aspects and some own proposals: 1) Calculation of the evolution of an expanding bubble originated by the explosion of a cosmic object that releases 50 Mt of energy in the terrestrial atmosphere, at a height of 5 km from the ground. 2) A new explanation of the white nights observed in Eurasia and of other phenomena related to the Tunguska's explosion of 1908.
