متن کاملNo consistent bimetric gravity?
Two-tensor, bimetric (or ‘‘f-g’’) gravity (BMG) was born as the fusion of the strong-interaction resonances of the 1960s (specifically that of a massive spin 2 field) with general relativity’s (GR) massless metric [1]. The idea was to join the two symmetrically by giving each its own Einstein-Hilbert action, then coupling the two resulting ‘‘spaces’’ through a nonderivative ‘‘mass term’’ that n...
متن کاملA longitudinal component in massive gravitational waves arising from a bimetric theory of gravity
After a brief review of the work of de Paula, Miranda and Marinho on massive gravitational waves arising from a bimetric theory of gravity, in this paper it is shown that the presence of the mass generates a longitudinal component in a particular polarization of the wave. The effect of this polarization on test masses is performed using the geodesic deviation. A the end of this paper the detect...
متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملBimetric Models of Gravity and Cosmology in the Early Universe
In the last decades, we have witnessed an astonishing progress in our understanding of the Early Universe and its evolution into the actual con guration we observe. General Relativity has been a key ingredient for this achievement, and it certainly provides the correct way to couple matter elds to gravity. However, in other fundamental theories (string theory, for example), we can nd an immense...
