@Fil Albuquerque,
Lawrence Krauss recently said that we got to redefine the meaning of Nothingness because we learned more about it...
(what a marvelous naive statement that was hehehe
)
My rebutal was simple...we don't get to redefine Nothingness for the same reason we don't get to redefine the meaning of the word Meaning... while its true that language evolves it never does regarding absolute terms.
