Dear Sir,
We have discussed relativity critically in our essay. Since GR is also an inverse square theory, if MOND is correct, GR would also need modification. But for this modified versions to work, some sort of unseen or "dark" presence is a must, which looks a lot like dark matter. It won't be described by particles in the way that dark matter is described - it may be described in a more wavelike form or a more field-like form. In other words, MOND can do away with dark matter but cannot describe the universe simply as the product of a tweaked Einsteinian gravity acting on the mass we can see. It modifies gravity, but through the backdoor it introduces extra fields, which mean that the distinction between dark matter and modified gravity isn't very clear. In a paper "No Evidence for a Dark Matter Disk within 4 kpc From the Galactic Plane" (http://arxiv.org/abs/1011.1289) the authors note that their findings directly contradict the predictions of MOND.
The energy "uncertainty" introduced in quantum theory combines with the mass-energy equivalence of special relativity to allow the creation of particle/anti-particle pairs by quantum fluctuations when the theories are merged. As a result there is no self-consistent theory which generalizes the simple, one-particle Schrödinger equation into a relativistic quantum wave equation. QED began not with a single relativistic particle, but with a relativistic classical field theory, such as Maxwell's theory of electromagnetism. This classical field theory was then "quantized" in the usual way and the resulting quantum field theory is claimed to be a combination of quantum mechanics and relativity. However, this theory is inherently a many-body theory with the quanta of the normal modes of the classical field having all the properties of physical particles. The resulting many-particle theory can be relatively easily handled if the particles are heavy on the energy scale of interest or if the underlying field theory is essentially linear. Such is the case for atomic physics where the electron-volt energy scale for atomic binding is about a million times smaller than the energy required to create an electron positron pair and where the Maxwell theory of the photon field is essentially linear.
However, the situation is completely reversed for the theory of the quarks and gluons. While the natural energy scale of these particles, the proton, meson, etc. is on the order of hundreds of millions of electron volts, the quark masses are about one hundred times smaller. Likewise, the gluons are said to be quanta of a Yang-Mills field which obeys highly non-linear field equations. As a result, strong interaction physics has no known analytical approach and numerical methods are said to be the only possibility for making predictions from first principles and developing a fundamental understanding of the theory. In QCD, the non-linearities in the theory have dramatic physical effects. One coherent, non-linear effect of the gluons is to "confine" both the quarks and gluons so that none of these particles can be found directly as excitations of the vacuum. Likewise, a continuous "chiral symmetry", normally exhibited by a theory of light quarks, is broken by the condensation of chirally oriented quark/anti-quark pairs in the vacuum. The resulting physics of QCD is thus entirely different from what one would expect from the underlying theory, with the interaction effects having a dominant influence.
There is an urgent need to rewrite physics.
