"Magical gods" in the conventional supernatural sense generally don't exist in any universes, insofar as a lot of the properties conventionally ascribed to them are logically impossible or ill-defined, but entities we'd recognize as gods of various sorts do in fact exist in a wide variety of mathematically-describable universes. Whether all mathematically-describable universes have the same ontological status as this one is an open question, to the extent that that question makes sense.
(Some would disagree with referring to any such beings as "gods", e.g. Damien Broderick who said "Gods are ontologically distinct from creatures, or they're not worth the paper they're written on", but this is a semantic argument and I'm not sure how important it is. As long as we're clear that it's probably possible to coherently describe a wide variety of godlike beings but that none of them will have properties like omniscience, omnipotence, etc. in the strongest forms theologians have come up with.)
Thanks, that makes more sense to me. I didn't think qualities like omnipotence and such could actually be realized. Any way you can give me an idea of what these godlike entities look like though? You indicate they aren't actually "magical" per se - so they would have to be subject to whatever laws of physics reign in their world, no? I take it we must talking about superintelligent AIs or alien simulators or something weird like that?
This is for anyone in the LessWrong community who has made at least some effort to read the sequences and follow along, but is still confused on some point, and is perhaps feeling a bit embarrassed. Here, newbies and not-so-newbies are free to ask very basic but still relevant questions with the understanding that the answers are probably somewhere in the sequences. Similarly, LessWrong tends to presume a rather high threshold for understanding science and technology. Relevant questions in those areas are welcome as well. Anyone who chooses to respond should respectfully guide the questioner to a helpful resource, and questioners should be appropriately grateful. Good faith should be presumed on both sides, unless and until it is shown to be absent. If a questioner is not sure whether a question is relevant, ask it, and also ask if it's relevant.
