But in a world of geeks where science fiction is apart and time travel exists, one can still travel back to before the annualment, research the question and declare that Penny (last name unknown) is really married and her name is officially Penny Johnson. The entire Big Bang world is fictional so anything is possible, even this premise since these guys are invovled with the sciences that might make that possible. Fiction is the world of the possible and can consider any "what-if" scenario including going around some legal exception. In the fictional world of Big Bang, Penny did have the last name Johnson in one of the many alternate universes, though not all of them.
