That is a too general statement. I can agree with some definition of observation. But then we never observe anything mathematical, still less infinite. Anyway, you seem to use “observation” as a criteria of reality.

OK. That is where we will be led, in the computationalist frame. > Incidentally, I don't think the Wiki article refutes Tegmark as you claim; > rather it just describes it. Read more carefully. I have refuted Tegmark in this list. Then I say that that wiki entry is very bad. Those are independent statements.
