Hi. I am fairly new to physics. I have recently read the first half of a book by Michio Kaku called “Beyond Einstein”, and im really struggling to get my head around the superstring theory. The superstring theory seems illogical for the following reasons... 1. Nature demands symmetry. So wouldn't it make sense for the unified field to have an infinite number of planes of symmetry - that of a sphere? 2. The superstring theory suggests that we live in a 10 dimensional universe. Is it possible to have symmetry in 10 dimensions? 3. The unified field is everything and everywhere. It is both the smallest and the biggest. It fills up the universe yet it is still one. So shouldn't it be expanding outwards, just as the universe is? 4. If the unified field is expanding then its mass would never be constant. If the unified field had a mass of 0, but still possess relativistic mass, then the centre point of the unified field would have a mass of 0, since it is not moving, and the outer-most part of the field would have a mass of...erm...whatever the relativistic mass is of a mass-less-particle traveling at the speed of light (not sure about that one). Wouldn't it be able to resonate at different frequencies (like the superstring), if the mass of the sphere had a dynamic range that could unify quantum physics and relativity? Anyway, I can't even find anything on google that clearly shows how the equation works (not that I would understand it) but my question is... Have physicists actually taken into account that the unified field might have a dynamic mass, which represents the expanding universe? Please forgive my ignorance, I just find it hard to learn about something that doesn't appear to conform to any kind of logic. Thanks.
