Anti-gravity and/or dark matter contributions from massive gravity
Recently, the static spherically symmetric solution of the gravitational field equations have been found in theories describing massive graviton with spontaneous breaking of the Lorentz invariance [1]. These solutions, which show off two integration constants instead of one in General Relativity, are discussed. They are candidates for modified black holes provided they are stable against small ...
متن کاملMassive Gravity
We review recent progress in massive gravity. We start by showing how different theories of massive gravity emerge from a higher-dimensional theory of general relativity, leading to the Dvali-Gabadadze-Porrati model (DGP), cascading gravity, and ghost-free massive gravity. We then explore their theoretical and phenomenological consistency, proving the absence of Boulware-Deser ghosts and review...
متن کاملFrom Massive Gravity to Dark Matter Desity
Massive gravity previously constructed as the spin-2 quantum gauge theory is studied in the classical limit. The vector graviton field v which does not decouple in the limit of vanishing graviton mass gives rise to a modification of general relativity. The modified Schwarzschild solution contains a contribution from the v-field which can be interpreted as the dark matter mass density. ∗e-mail: ...
متن کاملRecovering general relativity from massive gravity.
We obtain static, spherically symmetric, and asymptotically flat numerical solutions of massive gravity with a source. Those solutions show, for the first time explicitly, a recovery of the Schwarzschild solution of general relativity via the so-called Vainshtein mechanism.
متن کاملNonlinear partially massless from massive gravity?
We show that consistent nonlinear partially massless models cannot be obtained starting from ‘‘f-g’’ massive gravity, with ‘‘f’’ the embedding de Sitter space. The obstruction, which is also the source of f-g acausality, is the very same fifth constraint that removes the notorious sixth ghost excitation. Here, however, it blocks extension of the gauge invariance (appearing for mass to de Sitter...
