Abstract

In this work we propose an alternative scheme for an emergent universe scenario where the universe is initially in a static state supported by a scalar field located in a false vacuum. The universe begins to evolve when, by quantum tunneling, the scalar field decays into a state of true vacuum. The emergent universe models are interesting since they provide specific examples of nonsingular inflationary universes.

  • A tunneling scenario for the Emergent Universe would necessarily not be eternal.

    “Another alternative is perhaps a tunneling scenario (for instance, [13]). However, then the universe is necessarily not eternal.”

    From Quantum Instability of the Emergent Universe (2013) · cites this paper as [13]

    The Introduction (p. 4) says the initial metastable state in this paper’s tunneling scheme could exist only for a finite time. But the claim’s “necessarily” extends that conclusion to tunneling scenarios generally; the Conclusions (p. 17) propose applying the scheme to models with stable past-eternal static regimes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
