There is no shortage of cranks generating novel cosmological theories, but this writer doesn't seem to be one of them. He's interested in predictive power!

I think it's fascinating and enjoy this theory a lot, but the epistemics strike me a little funny. The mechanism itself can't be tested. If this mechanism exists, these observations would tend to be expected from a random sample of possible universes. There's absolutely no way to evaluate how "representative" our n=1 observation is.

I'm not yet convinced this kind of approach is valid, although I'm almost certain there's nothing better at a certain scale. empiricism is useless if you need a galaxy-scale particle accelerator.
