If it is true that “In infinite time and infinite space, whatever can
happen, must happen, not only once but an infinite number of times,” then
what does probability mean? In your example below, there must be an
infinity of worlds where Colin Powell is president and an infinity of worlds
where your 6-year old niece is president. Are you saying that the Colin
Powell infinity is bigger than the 6-year old niece infinity?

But there are likely many many more universes where Colin Powell is the next
president than there are where my 6 year old neice is. So it is a meaningful

But again we can make a probabilistic argument that there are many more
universes where house prices continue climbing than there are where all
houses become worthless tomorrow.
