The Galactic origin for the borders in the Earth history

TL;DR

This paper proposes that external galactic factors significantly influence Earth's geochronological boundaries and mass extinctions, supported by correlations in process scales, periodicity, and cause-effect relationships.

Contribution

It introduces a novel hypothesis linking galactic phenomena to Earth's boundary formations and extinctions, supported by empirical correlations and theoretical substantiation.

Findings

Galactic factors influence Earth's geochronological boundaries.

Periodic galactic processes correlate with boundary formations.

Impact origin hypotheses for ocean basins and plumes are supported.

Abstract

The external galactic key factor for developing of massive geochronological boundaries, as well as mass extinctions (ME) is proved based on chronological relationships of the impulses of globally short processes. External galactic key factor is also proved based on the coincidence of the scales of their developing processes, their regular periodicity in the formation of the boundaries of the Phanerozoic epochs and the presence of a unifying complex of cause-effect relationships for boundary processes. The hypotheses of the impact origin of ocean basins and plumes are substantiated, the assumptions about the unsteady nature of the Spiral Arms and the rotational acceleration of the Milky Ways core are confirmed.
