Many worlds is one of the more popular realist models, but it's quite rare for physicists to claim they think it represents reality. It's not taught in any textbooks I'm aware of and even now papers often dismiss experiments having multiple outcomes without even mentioning that they are doing so, coming to absurd conclusions as a result.
The situation has certainly improved a lot since the days of Everett, who was basically dismissed as a crack-pot.
- graycat 8y agoBut Everett has a cute case of Lagrange multipliers, or if you will, non-linear duality. :-)
- pbhjpbhj 8y agoI've seen Hawking quoted as saying MWI is obviously right. My statement was based on an IoP survey result I saw some years ago (I'm a theoretical physics graduate); I'll try and dig it up as my recollection could be wrong.
- akvadrako 8y agoHawking said it was right but that it's "just probability". It's not clear what he really thought about all those worlds being real. He didn't seem to believe in quantum immortality, so I don't think he took it seriously. There have been a few surveys over the years, but mostly of conference participants. The results depend heavily on which conference you attend.
