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.

As this system transits its orbital course, noticable shifts in gravimetric measurements, geological arrangement, meteorological patterns, technological functionality, and even psychosocial interaction will be observed. Depending on the total reaction to the shift, particularly during the transit through the mouth of the Dark Rift (which this system is currently experiencing and will continue to for another few years) there can be some extraordinary advancements in understanding and application of quantum physics with both energy generation, technological design and space transportation.

However, if the overall reaction is towards the negative side that understanding can also be used for weapons applications. This would be incredibly harmful for many of the other species inhabiting the local area surrounding this system. Consider that in the few years that intergalactic planetary recognition has been a functional science (less than 20 years) more than 500 planets have since been discovered, several of them possibly capable of supporting life.

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