The thing is the mathematical formalism of most if not all theories are directly mandated, as to be the consequences dictated by the logic of the initial premise(s), rather than the other way around.

To be truthful I don’t have a fixed opinion either, yet I am fairly familiar with the central issues. I would recommend if you ever want to look at all this more seriously, that is from the ground up, a book by David Albert entiltled “Quantum Mechanics and Experience”.

If you divide a wavefunction into component "worlds", there is no way to "Lorentz transform" that construction, you just have to start again with the transformed wavefunction. In other words, a division into worlds is frame-dependent (as well as being quantum basis-dependent), just as the Bohmian Mitchellhttps://www.blogger.com/profile/10768655514143252049noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-50783280496652424872010-05-17T22:44:41.615-04:002010-05-17T22:44:41.615-04:00Oy vey, there is always a theoretical way to "...Oy vey, there is always a theoretical way to "Save The Phenomenon" in Ptolemaic fashion, if you do not approve of nature's empirical verdicts.<br /><br />That has become standard operating procedure in theoretical HEP and cosmology in recent decades.<br /><br />Funding and status never need be at risk in the postmodern era.Robert L.
