It is the "magnetic" nature of gravity which is partial to the explanation of the perception of its "easing pull." Also, strangely enough, a quantum reasoning for the concept of "astrology." As this star system, Sol, orbits the galactic center, it experiences different frequencies of existential vibration. Different "magnetic pulls and energetic pushes" from the center of the galaxy if you will.

It perhaps might be easier to think of it as walking around an omnidirectional radio antenna and recording the different frequency variances you encounter as you walk all the way around it and running the frequency counter up and down along the entire length of the antenna.

The Astrology mythology came from the initial observations of the "clockwork" like nature of the movement of the observable universe and the psychoemotional patterns observed over time correlated to those observable movements. Rough "science" at best, but an important step in the right direction....

...Hence, using current relational equations, gravity will seem to be lessening. Add that to the numerous other observed shifts in existence.
