Impossibilities of the superstring theory

  1. Mar 21, 2003 #1
    So far in this past century, the theory of the superstring has held most promising oppertunities for unifying all quantum mechanics. However I noticed some very imediate flaws that eliminate the purpose of the theory. The theory is that everything is made of one-dimensional strings, whose vibrations give rise to fundamental particles. This takes place in a ten-dimensional universe requiring nine dimensions of space and one dimension of time. The described universe began with a big bang. The big bang is a theory describing for some reason a singularity where six of ten dimensions curled up, ending one universe, but allowing four dimensions to unroll, begining our universe, with three dimensions of space and one dimension of space. Now to disprove a ten-dimensional universe, lets begin with this.
    The big bang theory is a contradiction of itself. If the six dimensions of an old universe curled up from a big crunch, then for that universe to have existed to have a big crunch, it needed to have a dimension of time. When our universe unravelled, it had to have three dimensions of space, and one dimension af time. It would be impossible to have that dimension of time if it belonged to the old universe, thus when our three dimensions unravelled, separated from time, they would ceace to exist in he time-space continuum.
    Also, if there was a big bang and fundamental particles were made from superstrings, because of the mass and energy of the expanding universe, in accordance with Einsteins theory of general relativity, the universe would have instantly collapsed into a one dimensional cylinder with a diameter equal to that of the length of the superstring, this supercylinder relentlessly expanding upwards.

    The 6 curled dimensions can be curled into strange shapes called Calabi-Yau shapes. These shapes then determine the number of particle families and other properties. The entire theory is required to explain in mathematical terms the forces that govern our universe(or seem to at least).
    The fact that 6 dimensions are curled up need not be taken literally.

    This may help clear things up a bit.

    What is the "Strong Force"?
     
  6. Mar 22, 2003 #5
    The force that holds atomic nuclei together even though protons will repel each other via the electromagnetic force.

    so its only for photons?

    No, it applies to particles made of quarks.

    Does it apply to nuclear forces? Is it the same? I remember reading about how, through nuclear fusion, particles will become thermodynamic, and their energy holds the nucleus of the atom together. Is this true?

    The strong force is a nuclear force. I'm not sure what you mean by "the particles will become thermodynamic."

    To clarify, the strong force applies only to hadrons, which are particles composed of quarks. The two standard nuclear particles, neutrons and protons, are baryons, which are particles consisting of precisely 3 quarks (not 2, which are called mesons). So all nuclear particles are affected by the strong force. Indeed at such distances it is the dominant force.
    There is another nuclear force, the Weak Force. This is (pretty obviously) weak, and has been more or less unfied with EM.
