Impossibilities of the superstring theory

Click For Summary

Discussion Overview

The discussion revolves around the theoretical framework of superstring theory, its implications for unifying quantum mechanics, and the challenges it faces. Participants explore concepts related to the dimensionality of the universe, the nature of fundamental particles, and the compatibility of superstring theory with established physical theories.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant argues that the big bang theory contradicts itself regarding the existence of time in a ten-dimensional universe, suggesting that if dimensions curled up, time could not exist for the new universe.
  • Another participant mentions that the six curled dimensions in superstring theory can be represented by Calabi-Yau shapes, which influence particle properties, but notes that this need not be taken literally.
  • A modification to M-Theory is proposed, suggesting a different starting point involving two separate space-times, one being a 2D manifold and the other a 6D Higgs-type space-time.
  • Concerns are raised about the lack of observational evidence for supersymmetry partners and extra dimensions in nature, which some participants view as problematic for string theory.
  • String theory is described as a potential solution to issues in quantum field theories, particularly regarding singularities and the unification of general relativity with quantum mechanics.
  • Questions arise about the nature of the strong force and its relation to nuclear forces, with clarifications provided about the role of quarks and baryons in the strong force.

Areas of Agreement / Disagreement

Participants express various viewpoints on the validity and implications of superstring theory, with no consensus reached on the criticisms or modifications proposed. The discussion remains unresolved regarding the foundational aspects of the theory and its observational support.

Contextual Notes

Some limitations noted include the dependence on definitions of dimensions and the unresolved nature of the mathematical steps involved in the proposed modifications to existing theories.

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, beginning our universe, with three dimensions of space and one dimension of space. Now to disprove a ten-dimensional universe, let's 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.

A possible modification to M Theory.

This modification differs from the standard theory in that the universe starts with two separate space-times. One is a 2D manifold that meets the requirement for a Near-Kerr solution to Blackhole Geometrodynamics in 2D format. The other is a 6D Higgs type space-time of a size greater than 10^50th power in light years. The first starts smaller than the Plank scale by an equal amount.

But even in spite of String Theory solving a lot of problems(ie. Entrophy of Blackholes) it still in its current form commonly called M-Theory for Membrane or Magic has many problems of its own.

String Theory from it's start has always been based upon another theory called SuperSymetry. With SUSY type theories all matter particles have their counter-part in force carriers. The idea being that Fermions can transform into Bosons and back. The problem is that nature,as we know it, has no observational evidence for the Supersymetry partiners.

Another problem to some people is the added extra dimensions. These again have no direct observational evidence in nature.

The Theory that is proposed here is a modification to M-Theory that explains the problem of SUSY and those hidden dimensions. For the most part it is basic M-Theory. But its starting point is different.

Here's some basic ground work.

The original field theories of the Standard Model pictured particles as points in space-time. There are two standard field theory models, which while giving accurate data on the particles, has several problems inherent within.

The first of these is Quantum Chromodynamics. This is the theory that describes the Strong Force carrier.

The second is Quantum Electrodynamics. This deals with the combined electromagnetic and weak forces.

The problem with these theories is that not only have the two never been acurately combined, they both exclude General Relativity from their fold. Thus, at best, they are incomplete.
String Theory replaces the point particle with something that does not inscribe a point and as such avoids the singularity problem that normally generates infinities as an answer.

Also, instead of a long list of different particles one has different particles as manifestations of the same basic string vibrating in different modes.

String Theory is also the only theory where General Relativity not only can be combined with it. In fact, the basic fundamental state of the String is the Spin-2 carrier of gravity, the Graviton.
 
The first of these is Quantum Chromodynamics. This is the theory that describes the Strong Force carrier.

What is the "Strong Force"?
 
so its only for photons?
 
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?

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.
