A short note on

the universe as black hole reproduction

I did brain science at Cambridge. Now I'm a behaviour science professor. Read my shit.

I’m not going to pretend to understand this properly, but the main thing I took away is that old mate reckons:

  1. direct-collapse supermassive black holes somehow produce universes; then
  2. galaxies form around them and produce a bunch of stellar-mass black holes; then
  3. life evolves, resulting in technology that eventually generates a bunch of tiny black holes for energy.

So universes are black hole reproduction, in the natural selection sense. It’s not even the main point. Something about how the way the black holes produce universes means we don’t need to explain dark matter anymore.

This shorter, more punchy version tells us that people are paying attention to the theory.

And I’m not overly fussed whether this ends up being true or not. Just that this can be true makes me feel like my little articles talking about how we can’t understand the world, so we make everything an ideology are a little more salient.
