  > Space and time is quantized at the planck scale, which strongly suggests that our known universe is a simulation. I don't get the reasoning for this part. It seems analogous to, but even more absurd than looking at abstract art and observing that the artist had pneumonia.

  Isn't the actual simulation argument based on information density being bounded in a way that doesn't make sense. Something like we would think information density should be bounded by 3d. You have twice as much 3d space, you can hold twice as much information. But the physics argument (and I think it is still theoretical physics) is that it is actually bounded by the 2D surface area of that space, not the 3D volume. I forget the details of how this ties into simulation. I also think there is some math in general relativity that works out much better if we assume 3D space is actually the 3d-surface area equivalent of a 4d space (and not the 4d space time), which makes us more like a hologram of 4d space. But this is another one where I forget most of the details that actually matter. These combine give us the hologram simulation that pops up in pop culture from time to time, but what you read about in any blog or news article has nothing to do with the actual math and science behind the theories/hypothesis/what ifs.

  > Prove, no - but the best argument for a "God" is the simulation argument. It’s not “the best” argument; it’s just a popular one mostly publicised by people who think they know quantum mechanics. I am sure there is some sampling bias, but I have never seen someone who knew a lot about Physics believing in it (quite a lot of them are religious, though, but mostly in a classical deist way). > Space and time is quantized at the planck scale, which strongly suggests that our known universe is a simulation. There is no proof whatsoever that “space and time is quantized at the Plank scale”. You can build thought experiments about this being the smallest distinguishable length because of black holes, but even that implies making quantum mechanics and general relativity work at scale about which we know nothing. And even that is a far cry from spacetime discretisation. It’s exactly the same mechanism behind the creation of gods: at the time the most powerful things people knew were themselves and awesome natural events, so they imagined them that way. Now that we’re all about computers it is tempting to see them everywhere, but believing that it is the case because of some tenuous superficial similarities is a fallacy. In exactly the same way that von Neumann machines are poor models for a human brain even though on the surface they have similar functions.
