Jef, what I find frustrating about singularity theory is that I have no way
to use my most powerful tools: mathematical modeling.  I use math to
understand everything that I feel I know about.  Without equations, I am
left trying to describe things with words.  I like words, I'm a big fan of
them, but they don't get the job done.  I have yet to see, nor can I
conceive of how to describe the singularity with variables and good solid
system of simultaneous differential equations that can be solved to yield
insights and predictions.

Example: engineers study a field of math called feedback and control theory.
Negative feedback is what prevents most physical systems from reaching
singularities.  A speaker/microphone system would explode without negative
feedback.  Aim the microphone toward the speaker, the system amplifies
random noise until a howl is created, but that howl doesn't keep getting
louder until the system explodes because of the negative feedback imposed by
the physical limitations of the system.

I hafta think there must be negative feedback in the singularity, but I just
don't know what are those mechanisms.
