Conscious "events"

I take a particularly rigorous path in approaching the concept of 
consciousness; I'll share below a brief abstract of my current 
speculative position.
The Riemann Observer; Consciousness Coupled to Curvature

I believe that the leap of imagination required to grasp the concept of 
"physical consciousness," is a leap made in two conceptual stages; the 
first requires that we understand "conscious events" in a 4-dimensional 
spacetime, as comprising a minimum of two events, defined with no metric 
imposed.  For the present, we'll call one event "detection," and the 
other "perception."

The second, and most important stage, demands that we understand that 
the relative accelerations of the seperation between the geodesics 
corresponding to arbitrary detection and perception events, are not 
governed by the density of mass-energy, p.  We must instead consider 
relative acceleration as being governed by the Riemann curvature of 
spacetime [Misner, Thorne and Wheeler, 1973].  

As a consequence of this reasoning, I argue that a "conscious event" 
should be defined as an object whose geometry is the interval between a 
"detection event" and a "perceptual event."  Curvature is characterized 
by the Riemann curvature tensor, which is defined by the relative 
acceleration of nearby geodesics.  In the Newtonian limit (i.e., weak 
gravitational fields, low velocities and small pressures), Riemann can 
be given as,

R = G,

where G is the Einstein tensor.  

It follows from this that consciousness can be defined as changes in the 
interval geometry; specifically, the anisotropic component of curvature 
leftover from conscious events, propogated according to the Einstein 
field equation, which, in the absence of all coordinates, can be given 
in the limit as,

G = 8(pi)T = 0 = no matter, 0 curvature;

G = 8(pi)T = 4(pi)p = matter, curvature <> 0,

where T is the stress-energy tensor, and p is the density of
