[edit] Theory?

While I find Tegmark's proposals intriguing, I dispute calling this one a "theory". It's more of a provacative proposal that future theories adopt a particular and controversial featureCH (talk) 21:44, 21 August 2005 (UTC)

Isn't this just one of those ideas that occurs to pretty much everyone independently at some time or another? At least to philosophy students or distracted physics undergrads.

I'm not sure what "feature" you are referring to. Tegmark's "everything" or UE is frequently discussed as a potential TOE (for example in "New Scientist" magazine http://space.mit.edu/home/tegmark/toe_frames.html or... http://scienceweek.com/2003/sc031031-1.htm). It appears to be a theory rather than a tautology (which it is sometimes derided as). Please elaborate on what you mean by "feature" and why it should not be referred to as a TOE. In the meantime I'm going to remove the "feature of" insertion.Joncolvin 07:24, 9 December 2006 (UTC)
Being non-falsifiable, this proposal would not even qualify as science, let alone as a theory of everything. It is perhaps a "theory of everything" in a philosophical sense, but not in a scientific sense. Intriguing and attractive as it is, there is no way that experiment could possibly shed any light on the matter and therefore it lies outside the realms of science.

An extremely positivist viewpoint, Robin. This theory does in fact make predictions: one such prediction is that physics will become more "mathematical" as it progresses deeper towards the ultimate TOE. To date this prediction has been successful. Tegmark does not pretend that his theory is science; it is metaphysics, but metaphysics of a predictive nature. It bridges science and philosophy in a similar manner to the anthropic principle. Joncolvin 05:44, 18 April 2007 (UTC)

The last point of criticism "is self-contradictory because one cannot subsume all possible (partly contradictory) mathematical structures into one structure" is the result of a misunderstanding and has no bearing. The Ultimate Ensemble is not "one structure" ... the parts have absolutely no relation to each other. —Preceding unsigned comment added by 58.179.98.125 (talk) 03:25, 1 March 2008 (UTC)

This is a wikipedia article, not a research paper. It correctly reports what criticisms other physicists have made---there is even a citation showing you where this criticism was made. Just as a matter of interest, however, if the different parts have absolutely no relation to each other, and we are "in" one part, then presumably you agree with the criticism that the proposal is unverifiable, since we could never find any empirical evidence of the existence of the other, absolutely unrelated, parts.
