>Brent Meeker writes: Spacetime could be infinite without "everything >possible" existing. It might even depend on how you define "possible". >Are all real numbers "possible"? Norman Samish writes: 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. Norman
