Now that I see your response, I am sorry you bothered to too. I was under
the misconception that you were a person that tried to be helpful to people and
that you gave either a good answer or referenced the appropriate material. I am
rather disappointed with your response.

In other responses you tried to look professional but it seems you
gave it up here. What more is the above then an insult and a declaration of
superiority. I did not say, "I did not know what I was talking about". I said to
affect I didn't have the background to speak with authority. I have some
understandings about these things and when Im wrong I hope to be corrected. I
mentioned lack of background so nobody who wasn't as informed as the great Chris,
got the misconception I was speaking out of sources of authority.

You mean unmastered, not worded to your level of formal sophistication and

If your trying to be helpful you neither gave definition of a definition
or an example of how one looks.

So I made a mistake. This is not to important though because I was not
presenting this as a theory. What I was doing was laying out how the axioms should
look so I could present what I was thinking about and so I could find out what I
need to study before I could go snorkeling in such deep water. You said you always
try to be helpful and lay out specific suggestions of material which should be
studied. I see know evidence of this here.

This is merrily the set of instructions/laws whatever the universe would
use to store data if it was a computer.

Not poorly thought out. Not complete, more like it. I thought someone may
help me fix it or lead me to the proper place for me to lean the stuff. I also
thought others may have useful ideas of their own surrounding this subject.

This seems like a comment without foundation. What do you mean by
nonsense? What in the statement are you referring to?

I was merrily referring to the place where an observer receives
information.

This is why I need to learn more. What is a halting problem? Besides I
never said the universe was a computer. I was merrily using it as a tool to see
what you could say about the universe. It is called "lateral thinking by analogy".
The purpose is to develop an alternative way of looking at something.

See this is where your hostile. I did not claim to be doing science. When
I learn what's required and if what I's saying has merit I will derive this.
Besides you can predict some outcomes before you derive them.

It means that you only measure distance by the projecting of arbitrary
units and that lengths are only defined by ratios.

Are you really interested? I left it out because it didn't seem impotent.
I wanted you to deal with the content and not attack my background or wherever I
may of got it from. Your fist guess; a high school student was reasonable but
wrong. You other comment that I may have an undergrad level is close. I
have completed two years of University. I plan to complete an Honors Physics and
an Engineering certificate. To this point I hardly studied any physics because I
have been getting other requirements out of the way. I also have completed most
requirements for my engineering certificate.
So my background may be week now but hopefully in two years it may be up
to a reasonable enough standard so you can call my ideas somewhat coherent? So I
may not have a lot of the background you would like me to have but I am well
poised to learn it.

True but I was only seeking information on what to self study for what I
won't be studying formally. Also I may choose to study some imfomation theory
formaly anyway.

As I said I wasn't trying to sell it, I was looking for help and
interested in the ideas others may have.

I won't say anything about your last two paragraphs but you might want to
make sure that your position is not arrogant. And if it's not make sure that you
have communicated this well enough in the last part of your response.
Thank you for your response but now I don't even care if im on your kill
list. John Creighton
