Improved model for Earth

Postby parsoff on May 5th, 2018, 6:39 am 

I think it is about time that there comes an improved model for the Earth. That will help to understand more of the planet were we all live.

Constants are useable. The light needs 8.3 minutes to travel from the Sun to Earth. There is the axis angle of the Earth. There is the turning around the axis direction, to the east. There is the direction the two poles are turning where there is not jet a model for.

If there does not come an improved model then it is for those who want one to make one for them self.

It ranges between 8.167 min and 8.44 min, depending on whether the Earth is at perihelion or aphelion of its orbit.
There is the axis angle of the Earth.
which also varies, from 22.1° to 24.5°
over a period of ~40,000 years.
There is the turning around the axis direction, to the east.
Which also changes over time. Tidal friction caused by the Moon has the period of rotation for the Earth increasing in length by ~1.7 milliseconds per century. In addition, large seismic events (earthquakes etc.) can cause a small changes in the Earth's rotation
There is the direction the two poles are turning where there is not jet a model for.

We have a perfectly good model for this, it is a gyroscopic precession, which presently has a period of 25,772 years, and is caused by the gravitational torque applied to the rotating Earth by the Sun and Moon.
Basically, because the Earth is an oblate spheroid, the differential in gravitational pull across the width of the Earth of these two bodies tries to align the equatorial plane to them. The Earth, being a rotating body resists this and and precession or "wobble" of the rotational axis is produced instead.

If there does not come an improved model then it is for those who want one to make one for them self.
