Bodies that revolve always tend to move away from the centers that they revolve from. But what direction do the stars and heavens tend towards?

Cartesian Inertia as Inherent Motion

A body that ’tends’ towards some direction does not mean that there is a thought or desire inside the body that carries it there. Instead, it means that:

  • It is disposed to move there and
  • There is something preventing it.

‘Tend’ here means that the body is doing an effort to counteract such a resistance.

The body thus tends towards different directions at the same time

There are often diverse causes that act together on the same body.

  • These impede each other’s effect.
  • The same body can be thought of as tending in different directions at the same time.

Centrifugal and Centripetal Forces

Similarly, parts of the Earth:

  1. moves towards the center when they pushed to the center by the external [invisible spacetime particles] air-aether

For example, the stone curving in a sling along the circle AB would tend circularly from A to B, if the cord remained and its length regulated and determined the stone’s motion.

Centripetal Force

  1. moves away from the center when they are considered as a separate identity from that center.

The same stone will tend towards C from point A if the cord uniting it to the center disappeared.

Centrifugal Force

  1. moves away from the center when considered less massive than the other more massive parts [have more difference from the center-identity]

The stone would tend towards E if the circular agitation was ignored and it broke free from the sling’s force.

Superphysics Note:

It follows that centripetal force is from:

  • the unity of 2 identities
  • the external force to unite them

Centrifugal force is from:

  • the difference between 2 identities
  • the internal force to separate them

In Hinduism and Taoism, centrifugal forces are from the Negative Force or Shakti or Yin, while centripetal is from the Positive Force or Shiva or Yang.

In education, this is why external pressure has to be applied to learners who do not want to learn a certain topic. But this pressure is not needed when the topic is something that learners can easily and naturally identify with.

Therefore, parents should ask their children what topics they are naturally interested in, instead of forcing topics that they cannot identify with

Why Do Bodies Move Away From the Center?

To understand why the body leaves the center, imagine that the inclination of this stone to move from A toward C were composed of 2 other inclinations:

  1. Circular inclination along the circle AB
  2. Repelling inclination along the line DY
Centrifugal Force

Imagine the inclinations were in the following ratios:

Position of Sling Position of Stone
A A
B C
F G

1

Thus, the 2 inclinations together make the stone always move along line ACG.

If there were no sling, the stone, with the agitation that would move it along the circle AB, would move along the path DXY.

From this point of view, the stone at A tends (makes an effort) only to move directly away from the center D and towards E.

  • It is not at all more disposed to move toward H than toward I.

We can easily make a mistake and think that the stone would move either to H or I if we forgot the difference between:

  • the motion that it already has going away from D and
  • its inherent inclination to move

The air-aether [invisible spacetime particles] should be thought of as being the same as this stone R.

The gravitational territory of the Earth
In Cartesian Physics, the revolution of invisible spacetime particles around the Earth causes the tides and its oblate spheroid shape

Those that are at E tend of their own inclination towards P.

  • But the resistance of the other air-aether particles above them cause them to move along the circle ER.
    • This resistance is opposed to their inclination to move in a straight line.
  • This resistance when alone would make them move towards M which is the near the center T.

This is how they go towards the places that are directly opposite the center T of their gravitational territory.
