Hello to my google using fellows (the one Bing user out there, get out!),
Yesterday I posted about an argument made in a book I was reading, god actually, which states that a multiverse theory is desperate, has no proof, and is against Occam’s razor. I also showed yesterday how there is indirect proof that multiverses should exist, and that it is logical, not desperate. Today I will be showing you how it is also something which is against Occam’s razor. But first, I will give anybody out there who doesn’t know, the low-down on Occam’s razor.
Occam’s razor is a logical tool to decide on what is the most likely theory to suit observations. It does not mean that what Occam’s razor says is the correct hypothesis, it just says what is the most likely hypothesis, but it is usually correct. Occam’s razor, in a nut-shell, states that the theory which invokes the least amount of new assumptions is most likely the correct theory. This can be applied to our solar system… It is possible to model a solar system which is centered around the earth and holds up to all observations, but this would be highly complex, and it is much simpler to create a solar system which is centered with the sun.
Now I will show how it applies to our god vs multiverse discussion. The stance taken by Roy Williams and Paul Davies is that it is against Occam’s razor to invoke an infinite amount of universes to explain the coincidences of one universe, and it is much simpler to explain these contrivances with a god who designed them to be that way.
This is wrong. In fact, I believe it is quite the opposite. I’m going to list the assumptions made by each side of the argument.
Goddidit: It isn’t really a lot of assumptions, just one MASSIVE assumption, that there is an omniscient, omnipotent, supernatural, existing-outside-of-the-universe deity who, for no apparent reason, decided to create a universe, with intelligent beings in it, just for his amusing.
Multiverses: We know about quantum mechanics and the “all possibilities are achieved” consequences of it, we know how the universe was created, and that if it probably happened for us, then it probably happened for a lot of universes. The only assumption, (if you want to call it that) is the quantum fluctuations occur, and this has been proven.
That means assumptions go as follows, goddidit 1 – 0 multiverse.
Occam’s razor, because it is a scientific tool which requires natural causes, cannot be used to support a supernatural explanation because if there were supernatural forces in the universe, then Occam’s razor is useless.
I will leave you with a quote from Bertrand Russell, “Whenever possible, substitute constructions out of known entities for inferences to unknown entities.” Bertrand Russell, a British philosopher, logican, mathematician, historian and social critic.
