A friend once said the following hilarious quote: "I have thought of a theory so insane that even myself doesn't believe in it!
I just thought of a single one after walking out in the city and eating two gyros :)
When they ask me if I believe in extraterrestrials I like to reply that I don't. My last view before this one was that I surely believe there must be intelligent life (in so many galaxies, so many stars, blabla.. it MUST have evolved). Although the real question here is whether they have visited us or not. Nevertheless, I recently like to reply (maybe less seriously and just to surprise people) that I don't believe in extraterrestrials. And that is concluded from my belief in the multiverse :)
I have an obsession with an idea of the multiverse. It was derived from some scientific theories I might have heard somewhere but my own vision of it could reach a religious point of view. It's the acceptance of all possibilities.
Actually not exactly :)
The multiverse as a science fiction theory is a big set of all the possible infinite parallel universes. First of all it supports a better alternative of time travel theory and helps us to avoid the well known time traveler paradoxes. In a parallel universe I am not just sitting right here writting this blog but I may be still outside or I may be coding something on my computer or I may be 20 pounds lighter or I may be dead right now. The set of these parallel universes is all alternative realities I could be living right now, all alternative history events, all alternative possible worlds. Our universe is only one single posibility of all that exist in parallel. Some suggest another form of parallel universes where not only the different outcomes occur but also different set of physical laws. Through these kind of thoughts your perception can go far far away and maybe you will loose it as I did :)
Anyway, the point about aliens is: It's very improbable that a universe with billions of galaxies and each one bearing billions of stars, would not be host to at least one other intelligent species except us. But in the multiverse of infinite possible universes there must exist also those that happen to accommodate only us. There must exist those few but still sub-infinite sets of universes where for one or another reason it renders us totally alone inside them. Who can say that we haven't been unlucky (or lucky?) and our universe happens to be one of those lonely ones that out of seer luck happened to favor life on earth and nothing else? Or imagine some other sets of possible universes where a small number of intelligent species did exist somewhere else but at our current time they have all been destroyed by war or physical catastrophes. It's one improbable posibility but who can prove our universe is not amongst them?
And yes, we have not reached the improbable theory I was thinking at the way home yet!
I made a similar question about god. Ok, god is something that they ask me if I believe in but what I can't understand is what the heck is the definition of god. This is another big matter that I have made various strange thoughts about and I'd like to stretch it on one of my next posts.
I am not sure what god is and whether it can be defined. But let's assume that it's very improbable that he exists. According to Dawkins, the idea of all infinite, all powerful, all seeing god is like a skyhook coming from nowhere. If god created the universe then who created god? And who created the god of god? The idea of god just existing without needing a creator is so improbable in the views of science and evolution that the other alternative is simply to imagine an infinite perfect uberbeing or something. But then we simply put god outside the equation. So in order for such a perfect ultimate being called god to exist it has to not being able to be measured by scientific methods. But if we can't measure it then how can we prove it? In a nutshell that's how I think that god (or actually the notion of god) is highly improbable.
And then we come to the multiverse point of view. I know, I know, it's predictable, there is a universe or a few sets (yet sub-infinite) of universes in the multiverse where this improbable god entity exists. Then I come to the following question: "But if the ultimate being exists then why being a part of only a small sub-portion of the multiverse?". And then somehow I remember to have reached the conclusion that since we have proven that he exists in a single universe of the multiverse and since it's the ultimate being then he should be the god of all multiverse. And therefore I thought for once that I have proven the existence of god. Until it sounded so absurd right now I am writing this that I abandoned the idea :)
Crazy, I know. After falling down to the level of BITS, it felt like time to reach the universe of LCF (can't reach his personal site with his weird ideas right now). What's next? Sotsoft???
I am recently thinking of some common pitfalls in my multiverse view. Of course this is just my lousy view derived from the scientific theory about it (I have read somewhere that David Deutsch prooved mathematically that parallel universes exists, not sure what that could practically mean though). One problem with my lousy view of the multiverse (that every possibility I can or even cannot imagine could exist either in this or in another universe) is similar to the problam of god. If god is the ultimate being out there, couldn't we think of a god that is so perfect that is even more perfect than himself? Or the joke about the god who creates a rock so heavy that he even can't lift it?
Similarly, in the multiverse, which is the notion of endless posibilities, where everything can exist somewhere (even fairies and the flying spaghetti monster :), I could imagine of a multiverse that doesn't hold all posibilities, a multiverse with infinite universes in which the laws are same or in all of them there exists no god or where there are always extraterrestrials. With my notion that the multiverse is the infinite set of universe where every improbability exists then there also exist the improbabilities which abolish the great notion of the multiverse of all possibilities since it hosts also the possibility that deny itself. As in the skyhook example I can simply say that the multiverse which hold only half of the possibilities is wrongly called a multiverse but it is an uberverse (a set of parallel universes but not the only one) which is only a part of a greater set of uberverses called the multiverse. Then someone can tease me with an example of a multiverse as a set of uberverses that since it holds all the possible outcomes, it also holds the improbable probability that negates the initial notion of the perfect multiverse. Then I'd continue telling him this is another uberverse (similar to someone saying that there is a god who created god who created god who created god to infinity) or to say it better, the multiverse is the supreme notion that cannot be analyzed. And here I come to an analogy with the not to be analyzed supreme entity called god and I realize that the notion of multiverse I have created with my own philosophical thoughts about it, is a very similar idea to the absurd notion of god and thus the multiverse is a god itself.
Now, something even more crazy that came into my mind. Imagine this whole unreachable multiverse being a computer simulation in which we live inside. And that the people who wrote the software are living in another universe inside an uberverse inside a multiverse which they don't that is simply a part of another simulation of reality software of some other beings which are also...... you got the idea. Now think that to infinity and loose your minds! =)
I need to get a break..
