Unlike Many Worlds GRW is not deterministic, it adds a random term to Schrodinger's equation that only does 4 things: 1) It makes the new equation inconsistent with special relativity and thus observation. 2) It makes an equation that was already very difficult to solve even more difficult. 3) It makes Schrodinger's equation become nondeterministic. 4) It gets rid of those Many Worlds that so many people hate and fear. Maybe someday GRW Will do better but that would require a complete rewrite, and the prospects are not looking good: Impossibility of extending the Ghirardi-Rimini-Weber model to relativistic particles <https://journals.aps.org/pra/abstract/10.1103/PhysRevA.103.042216> John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> wrd -- You received this message because you are subscribed to the Google Groups "Everything List" group.
