I certainly don't assert the necessity of that anywhere. Perhaps you could
point out precisely where you think I do - maybe there is some

If the generated universe is somehow specified by the output bit string,
then it cannot be the same as the program and TM (combined if you prefer),
which in turn must operate in some dimension analogous to what we think of
as time (for a step-by-step computation to take place). It seems reasonable
to use the term 'universe' for this realm (as Schmidhuber does), but in any
case it requires an explanation just as ours does.

Flying rabbits from contrived universes (ie from some of the more complex
mathematical structures which should outnumber our own (presumed) one if the
challenge to Tegmark's hypothesis is correct) do not have to obey the
