From big crunch to big bang

Abstract

We consider conditions under which a universe contracting towards a big crunch can make a transition to an expanding big bang universe. A promising example is 11-dimensional M theory in which the eleventh dimension collapses, bounces, and reexpands. At the bounce, the model can reduce to a weakly coupled heterotic string theory and, we conjecture, it may be possible to follow the transition from contraction to expansion. The possibility opens the door to new classes of cosmological models. For example, we discuss how it suggests a major simplification and modification of the recently proposed ekpyrotic scenario.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Each of the other cosmological scenarios (pre-Big-Bang, ekpyrotic/cyclic, Aguirre-Gratton, and Bojowald loop quantum gravity) invokes special low-entropy conditions on some Cauchy surface, either asymptotically in the far past or at some moment of minimum size for the universe.

    “To the best of our understanding, each of these proposals invokes special low-entropy conditions on some Cauchy surface, either asymptotically in the far past or at some moment of minimum size for the universe.”

    From Spontaneous inflation and the origin of the arrow of time (2004) · cites this paper as [97]

    Section VIII, “Cosmological Implications” (page unavailable), describes the ekpyrotic model as beginning in a nearly vacuous, quasistatic state with a specified brane configuration, supporting the claim that this scenario assumes a special early state. It does not characterize that state as low-entropy or place it on a Cauchy surface, and the passages found do not establish the claim for all the other named scenarios. (LLM, conf=0.76)

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.
