Tegmark does not say his model has "zero information" (at least not in
the classic 1998 paper). His words were (pg 25 of my copy):

"In this sense, our "ultimate ensemble" of all mathematical structures
has virtually no algorithmic complexity at all."

Note, this is not zero, but simply small (at least compared with the
observed complexity of our frog perspective).

There is only one zero information object, and that is the set of all
descriptions (all infinite length bitstrings).
