Every good Whovian knows that time is not linear. Timeslips, deja vu, lost time - most of us have experienced one or more of these phenomena, though actual timeslips are the rarest. Most last no more than a few seconds and are often barely noticed or explained as a momentary loss of concentration. But if Time is indeed not a straight line, but just a mass of 'wibbly-wobbly, timey-wimey stuff', then why should they not be real?Worth considering.

After all, anyone who has had more than fleeting dealings with cats and small children knows that the so-called 'laws' of physics are little more than guidelines!
