'Black Holes' | 'For when God is lonely.' — a crude joke implying that appeals to black holes as evidence relevant to God are absurd or ad hoc.

As with the Big Bang joke, this is mockery, not argument, and it should be named as such rather than answered as if a real claim had been advanced. It is important, however, to be honest and precise about what the serious version of this point does and does not claim, since overclaiming here would be just as much an error as the joke's dismissal. What is true: general relativity predicts that at the center of a black hole (and, symmetrically, at the initial cosmological singularity) curvature and density become infinite, at which point the equations of the theory break down and cease to yield meaningful predictions — this is a genuine, uncontroversial feature of classical GR, acknowledged by physicists across the spectrum (Hawking and Penrose's singularity theorems formalize this). It is also true that most physicists expect this breakdown signals the limits of classical GR rather than a literal physical infinity, and that a full theory of quantum gravity (not yet available) would likely replace the 'singularity' with some better-behaved description. So singularities are, honestly, evidence of an incomplete physical theory at least as much as they are evidence of a metaphysical boundary — this is a point where intellectual honesty requires conceding real uncertainty rather than treating black holes as some kind of clinching argument. What the serious, modest philosophical point does claim: it is nonetheless notable, and worth taking seriously rather than dismissing with a joke, that our best current physical theory of gravity independently predicts boundary conditions (at the universe's origin and at black hole centers) where the theory points beyond its own domain of applicability. This is not 'proof' of God from black holes, and any apologetic argument that claims otherwise should itself be resisted as overclaiming. It is, at most, a data point consistent with — and mildly suggestive of — the older philosophical claim (developed independent of modern physics, going back to Aquinas's argument from contingency) that a complete, self-contained physical account of reality, closed under natural law with no external explanatory ground, is metaphysically incomplete: physical law-governed description, even our best available version of it, keeps generating boundary conditions it cannot itself explain from within.

Classical theism's account of God as the necessary, non-contingent ground of all contingent reality does not depend on black hole physics, but it is compatible with, and mildly corroborated by, the fact that even our most successful physical theories keep discovering edges — places where the theory says 'here my own descriptive resources run out.' This is consistent with the Thomistic claim that any purely physical account of reality, no matter how developed, describes a chain of contingent causes and conditions that, taken as a whole, still requires a non-contingent explanatory ground outside the chain (Aquinas's Third Way, the argument from contingency) — a claim about the metaphysical structure of explanation that physics, being itself a description of the contingent order, cannot in principle either fully vindicate or foreclose.
