I guess I don't get what's so meta about it. We're not talking about a universe that describes universes. Metaphysics = the physics of physics Metascience = studying science itself with science Metaphilosophy = Philosophy about philosophy itself Metadata = data describing data Gaming 'meta' = the game of how to best play the game 'Meta' is one of those ultra-abstract terms that obfuscates the meaning of whatever word it is attached to unless the listener gives or has given the word a fair amount of thought. Ah, then maybe that is why it is being used here.

I think that in the context of AR they actually are trying to talk about "universes that describe a universe". A "metaverse" is a "universe" in the sense that it's a shared 4D spacetime that you can explore (using some technology to give you a window into it). It's "meta" because it's layered on top of our "base universe": It's there to describe and augment the physical universe we exist in. For example: If, in your vision (via glasses, or a HUD, or a pane of glass or a brain implant), there's a big 3D arrow hovering above a road then the arrow exists in the "metaverse" and the road exists in the physical universe that the metaverse is describing.

> Metaphysics = the physics of physics Metaphysics isn't really the "physics of physics" though. It is part of philosophy, not physics. It isn't even the "philosophy of physics", since that names a branch of philosophy distinct from metaphysics (albeit they do have some points of overlap.) This is an example of where the meaning of a term is different from the sum of its parts. The philosophical implications of quantum theory (and its interpretations) is one part of the philosophy of physics, but the study of those implications go beyond just metaphysics proper and also extends to other areas of philosophy such as the philosophy of mind, epistemology, the philosophy of logic, etc. Conversely, there are some debates in metaphysics with which contemporary philosophy of physics doesn't concern itself with much, such as the relationship between existence and essence, or the problem of universals.

The definition of meta has changed over time. My understanding is it got the current "abstract" "thing aboout itself" definition long after the term "metaphysics" was coined, which probably originally meant "things we don't have a good name for but should probably file after the stuff about physics"

  Exactly, I believe the term comes from Aristotele's work "τὰ μετὰ τὰ φυσικά", literally "the after the physics", which may have just had a very practical meaning: writings that come after the physics writings.
