For in much wisdom is much grief, And he who increases knowledge increases sorrow.
(Ecclesiastes 1:18) NKJV
Gravity isn’t merely an implicit property of space-time as popular science (SciPop) has conveniently chosen to believe. That’s merely an opportunistic rationalization of circumstantial evidence.
God created gravity on the second day at the center of creation for the purpose permanently separating light from darkness, good from evil.
The purpose of creation is to bring about the permanent physical separation of light from darkness, day from night, good from evil.
– The Purpose of Creation
This also had the effect of forming the Earth in a specific quantity and mass. God also created instances of gravity for the sun, moon and some of the stars. Each one is unique, and has a specific quantity and frequency which causes the resultant bodies to have the mass and composition that we observe. The sun, for instance, is a created instance of gravity at the specific frequency of hydrogen.
The universe is spherical, Earth is the gravitational center, and it’s enclosed in a rigid crystalline firmament which has gravitational interactions with all stellar bodies which maintains the universe in its present stable state. It’s the %90 of the mass of the universe which SciPop thinks is “missing.” It’s not missing, it’s the firmament, as such there’s no need to fabricate mathematical contrivances like black holes and dark matter.
If there aren’t any black holes then they can’t collide. It seems much more likely that gravitational waves are being emitted from the center of the Earth for some reason. This reason is discernible, and the gravitational wave detections may indeed be a predictive testable hypothesis for it.

Gravitational Waves
We investigate the possibility that hell emits gravitational waves in response to fluctuations in the human death rate.
