Lukasz Andrzej Glinka ABSTRACT Recently, the author has proposed the global one-dimensionality conjecture which, throughout making use of the method of the primary canonical quantization of General Relativity according to the Dirac-Arnowitt-Deser-Misner Hamiltonian formulation, formally avoids the functional differential nature which is the basic obstacle of quantum geometrodynamics, a model of quantum gravity based on the Wheeler-DeWitt equation and resutling from quantization of the Einstein field equations. The emergent quantum gravity model is straightforwardly integrable in terms of the Riemann-Lebesgue integral, has an unambiguous physical interpretation within quantum theory, and introduces a consistent concept of global graviton. In this article, the axionic nature of the global gravitons, that is the hypothetical particles responsible for gravitation in the global one-dimensional quantum gravity model, is shortly described and, making use of fundamental methods of quantum field theory, the virtual states of such gravitons are generated.

The ramifications of this change Recall that this conjecture formally reduces the are highly non-trivial. Namely, the resulting functional differential nature of the Wheeler- model of quantum gravity significantly differs DeWitt quantum geometrodynamics from the Wheeler-DeWitt equation, because has throughout the primary canonical quantization a manifestly well-defined mathematical of General Relativity in the Dirac-Arnowitt- consistency defined in terms of classical Deser-Misner Hamiltonian formulation integrals and, therefore, is straightforwardly (Glinka, 2012; 2010). integrable. Moreover, the model has both a Let us sketch the state of affairs. The clear and unambiguous physical interpretation reduction follows from a simple and well- within the formalism given by quantum field known Jacobi's formula connecting the theory and, consequently, establishes a new variations of a metric and its determinant, and concept of graviton.
