How the Edge of Our Galaxy Defies Known Physics

Dear Physics Girl,

Perhaps you could explain this fun question.

I provided evidence of that the Universe is a Lightspeed Expanding Hyperspherical Hypersurface.  This is not a solution to Einstein's equations because spacetime curvature is defined only by the age of the Universe and thus it does not care for the Stress Tensor:

This link above refutes General Relativity and provides an alternative theory.
This also eliminates any support for Dark Energy since I was able to predict all SN1a distances from their redshifts.

I explained that DM away:

This explains the Coma Cluster, M33 Spiral Galaxy Rotation Curve, bullet cluster, galaxies without dark matter, weak lensing etc.  My theory does not eliminate the existence of large amounts of hydrogen in the intergalactic space. Those are LOADED MATTER.

The explanation comes from simple geometry. When the Universe is a hypersphere, there is an extra unaccounted for acceleration: Hypergeometrical Acceleration, which is given by v.c/R_0  where R_0=13.8 GLY, the 4D radius of the Universe.

Since it is an acceleration and not a force, matter that is traveling on the right velocity at the right distance will be LOADED into the galaxy and be held tenuously by this force. Notice that the velocity is exactly the Hubble Velocity at that given distance. You might object that the Hubble Velocity is a radial velocity (running away from us), but that is because you don't understand the meaning of angular momentum.

In my theory I used the Silver Surfer Paradigm to explain motion. On the footprint of each particle is a region of space (Fabric of Space or FS) that can be twisted and slanted (like a surfboard). The normal to that FS defines where the particle will land in the next step of the stepwise expansion of the Universe. Each step is equal to the de Broglie (actually, modified Compton Wavelength) of a hydrogen atom (0.19 femtometer).
Not unlike a surfboard, the FS can be slanted forward and twisted around the axis of the surfboard.  
Hence a body traveling at velocity v would have an angle of slope alpha such tan(alpha)=v/c
Interaction with Gravitation would add a rotation ( around the axis perpendicular to that slope)  to that FS until the body is in orbit.
This means that a body in orbit has a velocity that is NOT TANGENTIAL but OUTWARDS RADIAL.  The tangential motion is the result of the rotation angle.

So, not unlike other galaxies, all objects in orbit are actually running away.  That explain the modification to Newtonian Dynamics:
GM/d**2+v.c/R_0=v**2/d

instead of:
GM/d**2=v**2/d

Notice that when d is large:
v.c/R_0=v**2/d

v=(c/R_0)*d

which is the Hubble Law in my theory.

SO, my question to the Physics Girl is why is my theory being censored since it explains all cosmology with a simple epoch-dependent G and a Lightspeed Expanding Hyperspherical Topology. 

I say this here because I am not allowed to post my work anywhere visible.

Please disregard the SDSS data analysis since I retracted that already.  I was wrong because SDSS data was biased and I didn't know about that.
