It takes an infinite amount time for everything to happen an infinite number
of times. Therefore there is no time T where anything has happened an
infinite number of times (I'm assuming T= infinity has no "real" meaning in
any world). At any *particular* time T (at which we or anyone exists),
nothing will have happened an infinite number of times; thus at any time T
there will be far more universes where Colin Powell is president than my six
year old neice.
