Maybe this will help:
The All contains all possible output states of all Turing machines [among all manner of other info such as states of really messy universes] simultaneously. These states are given "Physical reality" by evolving Somethings in random order over and over. Some such sequences can arbitrarily closely approach or even exactly match those that would be output by a Turing machine for long runs of states [but not infinite runs of states due to the random input factor - no selection allowed]. All other sequences of all kinds of states also take place.
