- But it isn't a real event. The universe doesn't "split up" according
- to Everett. The whole beauty of Everett's work is that "collapse" is
- not a physical event and neither is some bizarre "splitting up" of the
- universe. Given the concerns you express in your article you should be
- in love with this work, except that you currently have no clue as to what
- it's really about.
-
- Conrad, you seem pretty interested in the interpretation of QM. Just
- get up from the keyboard now, walk over to the library, and look up Hugh
- Everett's book. Take 20-30 *minutes* to read his introduction, and
- then skip the rest if you want. You'll already have improved your
- understanding 100%, to the point where you won't talk anymore about the
- "splitting up" of the universe as some kind of bizarre physical event.
-
- Pretty good return on a half-hour investment, wouldn't you say? Go for
- it, you and Paul Budnik both. What's a half-hour, if your interest in
- QM interpretations is even mildly serious? It's not like there's
- thousands and thousands of interpretations which come as highly
- recommended (and admittedly, criticized) as Everett's.
