I responded to the above note in what has proven to be a controversial note.
An apology is in order.

At the time of sending the note, I was not familiar with the measurement
theory discussed by Bricken.  I charged into this newsgroup unfamiliar
with cyberspace and measurement theory like a bull in a china shop and I
wound up bruising myself.  I apologize for remarks which offended researchers
in the subject of virtual reality, etc, and note here that I retract
criticisms of the concept of space in measurement theory.

Please note that I do not withdraw all my criticisms, but here I restate them
in the hope of generating a rational response.  Here are some criticisms.

1. I cannot but interpret this to mean that humans have had the ability to
journey through time.  This to me is not a justifiable scientific statement.

> IMAGINARY:  contradictory spaces. Sqrt[-1].  Both True and False.  EG:

2. I object to illustrating contradictory spaces with wave propagation and
black hole interiors.

3. The above statement originated my confusion about spaces.  Perhaps my
ignorance is coming through again, but I cannot accept that concept of space
in Descartes' sense can be extended to include the measurement theory types
of spaces as perhaps orthogonal extensions.  The article gives me the
impression that somehow the measure theory spaces are somehow tangible 
through perception.

To be precise: I feel that the article submitted by Bricken borders on
science fiction, the merits of measurement theory notwithstanding.
Whereas research on virtual worlds is valid and unassailable, the dis-
cussion by Bricken seems not to add to the quality of the research: rather
concepts are introduced which detract from the metaphysical foundations of
the research field.

I admit that I am an outsider and am neither a mathematician nor am I involved
in research in cyberspace.  However, despite the voluminous hate mail that I
have received telling me to get lost, I intend to continue reading this news-
group.  I intend to learn more about the subject.  However, I feel that even
an outsider should criticise points which are objectionable.  This is a
SCIENCE newsgroup and participants should be meticulous about separating
SCIENCE and science fiction.  And those of you in the field who were offended
by my note should realise that other outsiders read this newsgroup and would
appreciate help in separating fact and fiction.

Perhaps my opinions still require revision.  Perhaps with this apology I can
generate rational responses.  If I am wrong or if I am just misinterpreting
matters, then please enlighten me.
