Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.

Observations from the James Webb Space Telescope have revealed a surprising number of young galaxies containing massive black holes at their centers, churning up the gas within only a few hundred million years after the Big Bang. Spectroscopic data indicates that these “hidden little monsters” harbor black holes weighing millions of solar masses. The abundance of growing baby black holes challenges theories about how supermassive black holes could have formed so early in the universe’s history. While astrophysicists expected JWST to find some early black holes, the sheer number uncovered has shocked astronomers and could rewrite models of galaxy and black hole formation. If confirmed, these observations suggest that massive black holes may have grown much faster than previously believed possible in the infant universe.

    With all due respect to Penrose – who is indisputably brilliant – in probability when you start to say things like, “X is 10^10^100 times more likely than Y,” it’s actuall much more likely that there’s some flaw in your priors or your model of the system than that such a number is actually reflective of reality.

    That’s true even for really high probability things. Like if I were to claim that it’s 10^10^100 times more likely that the sun will rise tomorrow than that it won’t, then I would have made much too strong a claim. It’s doubly true for things like the physics of the early universe, where we know our current laws are at best an incomplete description.
