Physical Review D, 1992
We describe a new approach to quantum gravity, based on a kind of mean-field approximation. The action, which we choose to be quadratic in curvature and torsion, is made polynomial by replacing the inverse vierbein by its mean value. This action is used to compute the effective action for the vierbein and hence its vacuum expectation value.

The cell in the field of gravity and the centrifugal field
Journal of Theoretical Biology, 1984It appears that the literature and logic that the earth's gravity has been one factor in the limitation of cell size, as well as being an important influence on the diversity of cell types and sizes throughout biological evolution. Analysis of the literature reveals an inverse relationship between the centrifugal force needed for intracellular ...

Physical Review D, 1986
We propose a Yang-Mills field theory of gravity based on a unitary phase gauge invariance of the Lagrangian where the gauge transformations are those of the SU(2)\ifmmode\times\else\texttimes\fi{}U(1) symmetry of the two spinors. In a classical limit this microscopic theory results in Einstein's metrical theory of gravity, where we restrict ourselves ...

We have seen how all matter and forces are build up from waves. These waves use the vacuum as medium to wave in. However, we did not say anything about gravity yet. Einstein’s general theory of relativity explains gravity from a geometrical perspective.

General Relativity and Gravitation, 1988
The authors define the covariant derivative of a single massive fermion field on a Riemannian manifold. A spin gauge theory of gravity is developed based upon: (i) local bivector spin gauge transformations of the elements of the Clifford algebra associated with a curved spacetime; (ii) the factorization of the mass term \[ -m{\bar \psi}\psi ={\bar \psi}
