Entanglement in a multiverse with no common space-time
Inter-universal entanglement may even exist in a multiverse in which there is
no common space-time among the universes. In particular, the entanglement
between the expanding and contracting branches of the universe might have
observable consequences in the dynamical and thermodynamical properties of one
single branch, making therefore testable the whole multiverse proposal, at
least in principle.Comment: 4 pages. Prepared for the proceedings of the Multiverse and

The entangled accelerating universe
Using the known result that the nucleation of baby universes in correlated
pairs is equivalent to spacetime squeezing, we show in this letter that there
exists a T-duality symmetry between two-dimensional warp drives, which are
physically expressible as localized de Sitter little universes, and two
dimensional Tolman-Hawking and Gidding-Strominger baby universes respectively
correlated in pairs, so that the creation of warp drives is also equivalent to
spacetime squeezing. Perhaps more importantly, it has been also seen that the
nucleation of warp drives entails a violation of the Bell's inequalities, and
hence the phenomena of quantum entanglement, complementarity and wave function
collapse. These results are generalized to the case of any dynamically
accelerating universe filled with dark or phantom energy whose creation is also
physically equivalent to spacetime squeezing and to the violation of the Bell's
inequalities, so that the universe we are living in should be governed by
essential sharp quantum theory laws and must be a quantum entangled system
