Brent, to me this is cryptic. Can you enlarge on what you mean? Your
statement seems to contradict what I've read, more than once; "In infinite
space and time, anything that can occur must occur, not only once but an
infinite number of times." I don't know the author or source, but I've
assumed this is a mathematical truism. Am I wrong?
As for "Are all real numbers 'possible'?" According to the definitions I
use, the answer, of course, is yes. I obviously do not understand the point
you are trying to make.
