Abstract: It is explained how one factor underlies the various manifestations of gravity. They include: (1) The primary cause of convergent gravity. (2) The secondary convergent gravity effect. (3) The divergent gravity effect —known informally as antigravity and formally as Lambda, or the cosmological constant. (4) The vorticular stress effect —responsible for inward spiral orbits. (5) Gravity waves —an acoustic-like effect. Also explained is the vorticular drag effect (often called the frame-dragging effect) and how it acts as a gravitational amplifier with the remarkable ability to reduce the potency of the centrifugal tendency. This amplification effect has profound relevancy for understanding the cohesion of spiral galaxies and the non-Newtonian nature of their rotation curves. The article essentially describes a comprehensive aether theory of gravity, one that is specifically based on the essence medium employed in DSSU cosmology (which is itself a model that was validated in 2015 per Physics Essays Vol. 28, No. 4, p455).Abstract: It is explained how one factor underlies the various manifestations of gravity.
