Here are some very simple observations about the episode of Horizon that was broadcast on the electric television this week concerning the topic of the multiverse (the idea that our universe is one of an infinite number of universes).
I was a little distracted by the fact that Katherine Parkinson was the narrator. I have seen her act in many productions, but listening to her voice I found it impossible to not visualise her as Jen from the IT Crowd, and expected Moss to take over at any minute.
Anyway, the hypothesis discussed is based upon the behaviour of particles in quantum mechanics where they appear to be both waves and particles simultaneously. Physicists are baffled by this, and one theory which is supported by some of the cleverest people on the planet is that there are an infinite number of universes in which every action that occurs causes a division of the physical at that point to cover every possible eventuality. This is far more complex than the simplistic example used in the programme in which a physicist used the example that, on the toss of a coin, he could either remain in the interview that was taking place, or leave. From this comes the idea of the infinite number of universes. For every micro-event since the Big Bang (and why not before?) there is a universe out there which shows the outcome of that event and every possible subsequent one.
Of course this is no new theory. I do not read much science fiction but the idea of parallel universes is not uncommon.
I am sure that all of you are familiar with the Ramacharitamanasa (if not please go and read it before continuing this) where Bhusundi describes being swallowed by Ram and experiencing infinite universes therein.
If there are infinite universes, then there must be an infinite number of them in which the theory of the multiverse has already been proved. Equally, there must be an infinite number of universes where it has been incontrovertibly proved to be total nonsense.
There are even universes out there in which people read this.
In other words it is beyond my comprehension. I have dwelt on it briefly and will now go back to preparing myself for the Rugby World Cup.
