Galaxy rotation curves in the light of the Spinor Theory of Gravity
Mario Novello, Angelo E. S. Hartmann, E. Bittencourt
We analyze the recently obtained static and spherically symmetric solution of the Spinor Theory of Gravity (STG) which, in the weak field limit, presents an effective Newtonian pot…
Beyond the Equivalence Principle: Gravitational Magnetic Monopoles
Mario Novello, Angelo E. S. Hartmann
We review the hypothesis of the existence of gravitational magnetic monopoles (H-pole for short) defined in analogy with the Dirac's hypothesis of magnetic monopoles in electrodyna…
A new gravitational black-hole
M. Novello, A. E. S. Hartmann
In a recent paper we have analyzed the Spinor Theory of Gravity (STG) which is based on the intimate relation between Fermi (weak) interaction and gravity. We presented the hypothe…
From weak interaction to gravity
M. Novello, A. E. S. Hartmann
We follow an old suggestion made by Stueckelberg that there exists an intimate connection between weak interaction and gravity, symbolized by the relationship between the Fermi and…
A new bifurcation in the Universe
A. E. S. Hartmann, M. Novello
We show that the combined system of general relativity with a non minimally coupled electromagnetic field presents a bifurcation in a cosmical framework driven by a cosmological co…
The cosmological constant and a scalar field coupled non minimally to gravity
M. Novello, A. E. S. Hartmann
We show that the combined minimal and non minimal interaction with the gravitational field may produce the generation of a cosmological constant without self-interaction of the sca…
Is the electromagnetic field responsible for the cosmic acceleration in late times?
M. Novello, A. E. S. Hartmann
We show that in the realm of general relativity a non minimal coupling between the electromagnetic and the gravitational fields may produce an era of accelerated expansion.
