I did not mean to imply that I had actual knowledge of QM, just that I had more now than before. If I was interested in understanding QM in more detail, I would take a course on it at my college. It turns out that I am so interested, and that I plan to take such a course in Spring 2013.

I also know that there are people on this site, apparently a greater percentage than with similar issues, who disagree with EY about the Many Worlds Interpretation. I have not been able to follow their arguments, because the ones I have seen generally assume a greater knowledge of quantum mechanics than I possess. Therefore, MWI is still the most reasonable explanation that I have heard and understood. Again, though, that means very little. I hope to revisit the issue once I have some actual background on the subject.

EDIT: To clarify, "similar issues" means issues where the majority of people have one opinion, such as theism, the Copenhagen Interpretation, or cryonics not being worth considering, while Less Wrong's general consensus is different.
