- Abstract summary: braneworld scenarios postulate that the spacetime we effectively observe is actually a 4-dimensional brane embedded in a higher-dimensional spacetime.
We propose an experimental test that uses a pair of gravitationally interacting identical particles to determine the validity of certain braneworld models.

- Abstract: Various attempts to go beyond the theory of General Relativity start from the
assumption that spacetime is not a 4-dimensional but rather a
higher-dimensional manifold. Among others, braneworld scenarios postulate that
the spacetime we effectively observe is actually a 4-dimensional brane embedded
in a higher-dimensional spacetime. In general, braneworld models predict a
departure from the Newton gravity law in the nonrelativistic regime. Based on
this fact, we propose an experimental test that uses a pair of gravitationally
interacting identical particles to determine the validity of certain braneworld
models and provide numerical results that should be compared with experimental
data. In particular, we consider the Randal-Sundrum braneworld model and study
two cases of 5-dimensional gravity theories: the Einstein-Hilbert gravity with
the negative cosmological constant and the Einstein-Gauss-Bonnet
(nearly-Chern-Simons) gravity.

We find that discriminating between the theories will be very difficult until experimental control over low frequency quantum optomechanical systems is pushed further.

The mass of the universe is a distribution of non-zero values of gravitational constraints.
A formulation of the Euclidean quantum theory of gravity is also proposed to determine the initial state.
Being unrelated to ordinary matter, the distribution of its own mass affects the geometry of space.

We show that there is no clear distinction between entanglement mediated by the Newtonian gravitational field of a body and entanglement mediated by on-shell gravitons emitted by the body.
This suggests that Newtonian entanglement implies the existence of graviton entanglement.
