Big Bang Theory: Does general relativity accurately model space's birth-growth?

“Yes, after all…
  • General relativity makes very accurate predictions

    Several lines are spiraling into a ball in the middle.

    General relativity has made remarkably accurate predictions, and continue to be in accurate in whatever it models.

    These are four things general relativity accurately predicted:

    • Gravitational waves from black holes merging.
    • The rate change of Mercury's orbital ellipse orientation.
    • The bending of light in gravitational fields.
    • The universe’s general expansion (from a hot-dense phase)

    This is relevant because the radical and highly precise things general relativity predicts seems so improbable that “chance” is a bad explanation for the theory’s success.

    So? Plausibly General Relativity's success is limited in scope.1

  • Space expanded from a hot dense state

    There is a ball with 12 arrows all pointing away from it surrounding it.

    The universe (all of space, time, and matter) really did expand from a single hot dense state, whether or not it began as a singularity.

    See this page to check out these 3 arguments,:

    This is relevant because it is a very surprising confirmed prediction of General Relativity, and might inductively warrant a tentative belief that the backwards contraction reaches the singularity point based on its clear past trajectory.

    So? Plausibly General Relativity’s success is limited in scope.1

“No, after all…
  • General relativity may fail at Quantum Sizes

    A barricade.

    General relativity “breaks down” in quantum-sized settings insofar as its predictions may no longer apply; we need a theory of quantum-gravity to unify quantum mechanics and general relativity.

    After all…

    • Quantum influences may rub out predictions of General Relativity

    This is relevant because the size at which singularities are predicted and modeled by general relativity is less than the Planck length (i.e. quantum size).

    By way of response, however…

    • We ought to give General Relativity's predictions benefit of the doubt.
    • Independent lines of evidence for a singular beginning supplement General Relativity's prediction, amplifying the likelihood that it's prediction is accurate.
