Stability, Singularities and Mass Thresholds in Child Universe Production: a concise survey including some recent results and prospects
Stefano Ansoldi, Eduardo I. Guendelman, Idan Shilon
We present a review of selected topics concerning the creation and evolution of child universes, together with a concise account of some recent progress in the field.
Universes out of almost empty space
Stefano Ansoldi, Eduardo I. Guendelman
Baby universes (inflationary or non--inflationary) are regions of spacetime that disconnect from the original ambient spacetime, which we take to be asymptotically flat spacetime.…
Absence of the Fifth Force Problem in a Model with Spontaneously Broken Dilatation Symmetry
E. I. Guendelman, A. B. Kaganovich
A scale invariant model containing dilaton and dust (as a model of matter) is studied where the shift symmetry is spontaneously broken at the classical level due…
Child universes UV regularization?
E. I. Guendelman
It is argued that high energy density excitations, responsible for UV divergences in quantum field theories, including quantum gravity, are likely to be the source of child univers…
Initial Singularity, Lambda-Problem and Crossing the Phantom Divide in Scale Invariant TMT Model
E. I. Guendelman, A. B. Kaganovich
In the framework of the scale invariant model of the Two Measures Field Theory (TMT), we study the dilaton-gravity sector in the context of spatially flat FRW cosmology. The scale…
