In contrast to GR, discrete aether is a quantum gravity (QG) that is completely consistent with GR within its limits and QG further defines object futures at both the Planck scale as well as at the black hole scale.
The deflection of starlight by the sun, d, occurs at about twice the value expected by classical Newton's gravity and the mass-equivalent energy of light. Science has known this for many decades. Einstein's general relativity explained this extra deflection in the figure below as a first order expansion of the GR equation that shows how gravity distorts space and time. That is, given the equivalent mass of light, GR predicts twice the deflection of Newton’s classical gravity and numerous measurements validate that fact.
Discrete aether and its QG provide a different explanation for starlight deflection by the sun, but that prediction also agrees with measurements since quantum effects show a factor of two doubling for both charge and gravity. For the quantum spin of an electron the gyromagnetic ratio, g, also has about twice the classical spin of a charged sphere. For an electron, the gyromagnetic ratio is how it oscillates in a magnetic field as
The up or down duality of quantum phase has no classical meaning in GR and in effect quantum spin doubles the frequency or energy of a quantum action from the action of a classical spinning charge. The distortion of space and time embodied within GR emulates the factor of two that fundamentally derives from the nature of QG.
A classical spinning charge will only orient itself up as a precession along a magnetic field and there is no meaning for up versus down in the absence of a magnetic field since the spinning charge would have opposite phase from up and down. A rotating classical charge in a magnetic field radiates with a classical frequency or energy that is one-half of the quantum frequency and a classical spinning charge then slows down as it radiates and loses energy. A quantum spin reorients when it radiates, but since a quantum spin exists in a superposition state of both discrete spin states, a quantum spin cannot radiate without some kind of electric or magnetic field. The meaning for a classical transition to a down spin is to spin in the opposite phase, changing the phase of its radiation by p. But a classical spinning charge always precesses along the magnetic field lines for both spin phases.
The figure below shows how gravity biphotons relate to the photon exchange bonds of charge for atoms and molecules. The hydrogen charge bond is an exchange particle of Rydberg energy at 3.3 fs period, and that exchange particle is in resonance with the electron in hydrogen with a period tB of 1.1e-21 s, the ratio of which what eventually defines c as 3e8 m/s along with a charge radius. The orbital period of the electron relative to the period of the universe is the scaling that defines gravity as proportional to charge force.
