At work I discovered the previous day’s sign-in sheet had three signatures each of which was dated 4/16/2012.
There are two explanations of this that I am considering.
The Mistake theory: Somebody goofed up and wrote the wrong date, which was unthinkingly copied by the next two signatories.
The Time Traveler theory: Yesterday, my work place was transported back in time two years because of a break in the space-time continuum.
The time-traveler theory is exotic, sure, but think about the mistake theory: it is ad-hoc. It postulates that someone (a) goofed up and that (b) the next person unwittingly copied the goof-up, and (c) a third person unwittingly copied the goof-up. I don’t know if we can stomach such an ad-hoc theory, especially when we have the much simpler theory that my workplace just traveled back in time (that’s only a single assumption, whereas the other theory has three!).
In case you’re wondering: yes, this post is a parody. It is closely tied into the reasoning I have used concerning miracles (see here and here) and the logic of explanation (see ‘Right Theory, Wrong Theory‘).
