Earth: 15 Million Years Ago

TL;DR

This paper proposes that due to relativistic effects and the solar system's orbit around the galactic center, Earth's axial tilt and seasons have changed over 15 million years, supported by geological evidence of historical ice accumulation.

Contribution

It introduces a relativistic model linking galactic orbit dynamics to Earth's historical axial tilt and climate changes, a novel approach in geophysical and astrophysical studies.

Findings

Earth's axial tilt was aligned with its orbital axis 15 million years ago.

Global ice accumulation was higher 15 million years ago, with sea levels lower.

The Earth's climate has undergone significant changes due to galactic orbital effects.

Abstract

In Einstein's general relativity theory the metric component gxx in the direction of motion (x-direction) of the sun deviates from unity due to a tensor potential caused by the black hole existing around the center of the galaxy. Because the solar system is orbiting around the galactic center at 200 km/s, the theory shows that the Newtonian gravitational potential due to the sun is not quite radial. At the present time, the ecliptic plane is almost perpendicular to the galactic plane, consistent with this modification of the Newtonian gravitational force. The ecliptic plane is assumed to maintain this orientation in the galactic space as it orbits around the galactic center, but the rotational angular momentum of the earth around its own axis can be assumed to be conserved. The earth is between the sun and the galactic center at the summer solstice all the time. As a consequence, the rotational axis of the earth would be parallel to the axis of the orbital rotation of the earth 15 million years ago, if the solar system has been orbiting around the galactic center at 200 km/s. The present theory concludes that the earth did not have seasons 15 million years ago. Therefore, the water on the earth was accumulated near the poles as ice and the sea level was very low. Geological evidence exists that confirms this effect. The resulting global ice-melting started 15 million years ago and is ending now.
