Transition to Zero Cosmological Constant and Phantom Dark Energy as Solutions Involving Change of Orientation of Space-Time Manifold
E. I. Guendelman, A. B. Kaganovich
Solutions with degenerate metric ( or ) in the first order formalism (FOF) are physically acceptable: they may describe topology changes (Horowitz) and red…
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.…
Child Universes in the Laboratory
Stefano Ansoldi, Eduardo I. Guendelman
Although cosmology is usually considered an observational science, where there is little or no space for experimentation, other approaches can (and have been) also considered. In p…
Solitons as Key Parts to Produce a Universe in the Laboratory
Stefano Ansoldi, Eduardo I. Guendelman
Cosmology is usually understood as an observational science, where experimentation plays no role. It is interesting, nevertheless, to change this perspective addressing the followi…
Fine Tuning Free Paradigm of Two Measures Theory: K-Essence, Absence of Initial Singularity of the Curvature and Inflation with Graceful Exit to Zero Cosmological Constant State
E. I. Guendelman, A. B. Kaganovich
The dilaton-gravity sector of the Two Measures Field Theory (TMT)is explored in detail in the context of cosmology. The model possesses scale invariance which is spontaneously brok…
k-Essence, Avoidance of the Weinberg's Cosmological Constant No-Go Theorem and Other Dark Energy Effects of Two Measures Field Theory
E. I. Guendelman, A. B. Kaganovich
The dilaton-gravity sector of the Two Measures Field Theory (TMT) is explored in detail in the context of cosmology. The dilaton ϕdependence of the effective Lagrangian appears onl…
