I use the word "conjecture" slightly differently than a mathematician
would. I use this word because it is the best word to describe the
tentattive kinds of relationsships I seek to manipulate. Yet at the
same time, a conjecture can never be proven or disproven.

My usage of the word conjecture is not the same as the common usage. A
conjectural statement, in my scheme, is a statement which is based on
existential indeterminacy which would form a valid mathematical
statement under the assumption of either existence or nonexistence.
Such objects are different from the standard conjectures that are
common in math, science and elsewhere. Conjecture, in my usage, cannot
be proved. All you can do is demonstrate consistency with mathematics.
If a conjecture forms a valid mathematical statement under the
assumption of existence, then it's a valid conjecture in the sense
that it will be consistent with every other conjecture in this
construction.
