Gravity as Space Density, backwards

Space density as gravity is backwards. The denser the space the slower you would fall through it due to its resistance. This is the opposite of reality. Space density would have to go down in free fall rather than up.

Actually, the concept of spacetime density causing gravity works just like the path of light bending inside some material, for example like in a fiber optic cable which has radially varying density, or in the more common case of a glass-air interface. Yes, the medium is denser and the light travels more slowly, but that doesnt stop it from curving. In the case of the fiber optic cable, the light actually spirals around the center....just like a planet orbiting a star! In extreme cases, the increasing density of spacetime can cause the effect of slower movement to "overtake" that of refraction (gravity). Then you get cases where the image of an object falling into a blackhole appears to hover above the event horizon, and also, as is noted in the Felber "antigravity" phenomena, a black hole approaching an object at a speed faster than 57.7% that of light will actually be repelled.

Why do you mean? The light behaves exactly by such way, for example at the case of relativistic aberration and/or gravitational lensing effects near heavy objects.

speed of light is invariant regarding density D of space
all other motion will have slower speed with density increasing
in centre of black holes and neutron stars density D of space is so strong to transform all the particles back into QS of space

D = (m x G ) / dP^2 ...... density in the centre of star
