While my dreams sometimes seem to derive their content at random, often I know the exact inspiration of the odd nightly workings of my mind. A while ago I happened to see a segment on CNN about a young lady who almost died from H1N1 and then that evening I read Heinlein’s recursive time travel tale “By His Boot Straps.” That night I had a rather odd dream about a time traveling bacterium. Yes, I do know that H1N1 is a virus, but even in a dream I somehow knew that only a bacterium would work. So, here is the story of the time traveling bacterium.
Naturally enough, after it goes back it will then move ahead in time at the normal pace and will (let us assume) eventually met up with itself. Then the pair (or rather the one) will also go back in time. Once more they (or it) will go forward in time at the normal pace and the pair (or one) will meet up with itself once more. The four (or one) of them will then go back once again, only to travel forward again, and thus there will be eight (or one). The eight (or one) would, of course, go back again and then there would be sixteen (or rather just one). And so on.
Now imagine that this bacterium dwells within the body of a human being. Naturally, the immune system of the body will attempt to destroy the bacterium. Unfortunately for the host, the bacterium simply travels back in time when it is threatened with destruction. This, of course, merely multiplies the bacterium. It keeps traveling back in time, multiplying and multiplying via this method. Of course, eventually the bacterium will reach half the population that would kill the host. When it makes the next jump back in time and the forward trip to meet itself, this will result in the death of the host. Horribly, the host will seem to die instantly as the lethal population suddenly appears in his/her body.
The bacterium will, of course, end up in other hosts and repeat the process over and over again. With enough time, it would seem that the bacterium would eventually destroy all susceptible organisms on earth and perhaps crowd out everything else-thus resulting in an earth with a population of one.
