Amazing ... and where do waves originate, in your so professional opinion? Do they arise from a source or sources outside of the Universe? Tie your shoelaces, ballerina. The ‘vacuum state’ exists inside the Universe God Created, thus ALL the waves are a product of an already created environment in which they arise. Just keep spinning, ballerina, you may get this turned completely around in readers’ minds and you won’t look so feckless. Enjoy your dance.
The "waves" described in the heuristic explanation aren't really waves, they're wave functions. [A better term is actually state vector.] There argument made in the blog isn't a precise statement of physics. It's a hand waving argument for lay people. They originate out of the vacuum -- that is -- literally -- from nothingness, and certainly not out of the material universe.
