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.
