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:
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
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
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.
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…
