Strings, Uncertainty & Infinity

(disclaimer: I don't have a degree in Physics, Mathematics or Philosophy. The idea I am presenting are not fact. Actually none of the references I used are established as facts. However my ideas are based on my interpretations of theories that are widely accepted as true or highly likely. Keep this in mind, Newton's theories have been considered fact for roughly 350 years. They are now easily shown wrong. They are VERY close to the truth, but not 100%. His theories fall apart at the macro (galactic interactions) and micro (atomic particles) levels.)

I've tossed out a theory of the Omniverse. The Omniverse is infinite and is made up of an infinite number of universes. Michio Kaku states in his book 'Visions', “At present, the fundamental problem with sting theory is that millions of solutions of the theory have been found, but none which precisely matches the known spectrum of quarks, gluons, neutrinos, etc. Many people have despaired of ever finding all the solutions of string theory to find our universe.” I contend they will never find all the solutions because there are an infinite number. This plays right into my theory. But before I get too head of myself, let me explain String Theory, as I understand it.

At its most basic, String Theory states that everything is made up of vibrating “strings”. Their frequency, vibration, determines its properties. Quantum particles are made up of these strings. There should be an infinite number of frequencies, and thus an infinite number of particles. This is what troubles the string theory physicists. If there are an infinite number of solutions, they cannot determine if the theory is correct or not. They need to solve it with the variables that produce the properties that are present in our universe to do this. At present that is the only way we can know with any certainty that the theory is correct.

So String Theory would give us a fundamental understanding of the foundation of the universe. With that understanding we should be able to understand why the universe acts as it does. Steven Hawking has commenting that knowing the theory to everything would be like knowing God. He's right. With that level of knowledge we could do nearly anything. Many String Theory physicists actually do not feel that their solution will be the theory of everything, but just the next step. Only time will tell. We don't know what exists outside our universe. Will String Theory tell us? Perhaps not 100% but it can give us glimpses.

String Theory can calculate millions, perhaps an infinite number of universes. Who's to say they don't exist? There is nothing that states our universe is the perfect one. Many, including Hawking have suggested that because we are here it's proof that ours is the best because of the extremely sensitive thresholds of our physical universe. But with an infinite number of quantum particles couldn't another universe, with totally different physical principles , be created? That universes Newton might come to different conclusions than ours because of the different particles that make it up. If Sting Theory is correct however, those strings would be fundamental to any of the universes, successful or full of a soup made up of quantum particles that cannot interact in a constructive manner.

The Heisenberg's Uncertainty Principle fits in here nicely too. Basically it states you cannot ever know anything for certain without observation/interaction. The classic example is Schrödinger's Cat. This poor cat is in a box. You don't know if it's alive or dead. Without looking in the box you can never know for sure. But rather than leaving the answer in limbo, the answer has to be both. The cat is alive and dead at the same time.

If there are an infinite number of solutions to String Theory then there has to be an infinite number of universes created from that uncertainty. Our universe is far from perfect so it makes logical sense that there has to be more. An infinite number of experiments looking for the perfect universe.
