I use the term Reality to indicate the sum of everything. If "universe"
is to be used for this, how then would we describe the relation between
our own Big Bang and its subsequent infinitely large spacetime bubble, and
that of other Big Bangs and their subsequent bubbles? In fact, I recall
that during one particular discussion of parent-child lines of Big Bangs,
I was forced to name our own Universe the "Socrates Universe" in order to
keep track. Who knows, maybe someday it'll become official.

Of course this leaves open the question of what to name our own little
nook within the Level IV worlds. Given that some Level IV worlds simulate
and overlap other Level IV worlds, our "location" may not be very well

Nonetheless, I hereby dub our home the Bayes Process.

So my address is currently:

USA, Earth,
