well - it's time for a definition.
O i'm a big fan of Turing; and mathematically i'm
O O O a contructivist. so i'm willing to take a risk
O and restrict myself to computable structures.
O since we started all this with "people living
O O inside numbers", let's stick to numbers. (no
O O worries - computable numbers are isomorphic to
O O computable structures. and heck - Turing's big
OO paper was about these numbers. so.)
O O O definition: the multiverse is the set of
O O O computable numbers.
OO O ...
O OO O
O O O O for the layman - what does this mean?
O O O
O O O O O a computable structure is anything that is
O O OO produced in a step-by-step manner, following a
OO OO O fixed set of rules, where no intelligence is
OOOO O required. its anything that could be produced by
O O O OOO a machine.
O O O OOO
O O OOOO computable numbers are those number that are
O OOOOO O made in the same way. pi is a good example -
O O OO OO there is a well known ruleset for writing out
OOO O O O the digits of pi. it requires a lot of work -
O OO OOOO but the process is simple.
O OOO O OO
OOOO O OO it may not seem like it, but we don't lose
OO OOO OOO anything by considering only numbers. the
OO OOO O O more complicated structures (words, sets,
OO O OOO O hierarchies, arrangements of atoms, ...) can be
OOOO OO OO encoded as big numbers. (trust me, it's okay.)
OOOO OO OO
OOOOOOO O besides - the other universe are bound to be
OOOOO OO O extremely strange to us. maybe they don't have
OOOO OO O movement, only growth? we'd better convert
OOOOO OOOO everything over to numbers so that we're all on
OOOOOOOOOO equal footing.
