I've seen some rather philosophical or interpretational questions pop up lately. These questions tend to get closed very quickly. I'm wondering if this is neccessary, since such questions can have interesting or enlightening answers. This is not about purely philosophical questions, nor about speculative or esoteric stuff, but rather about
- philosophy of physics/science
- interpretational issues of physical theories
and to a lesser extent
- epistemological and philosphical issues, as long as they are relevant for physics.
A couple of examples:
- Why is the 'multiverse' critized as being non-physical?
- Is Bayesian 'degree of belief' subjective? If so, how can it be justified?
- Is the universe infinite? (spatially, or in time)
- Why can't physics say something about X?
And some real examples (admittedly not the best):
- Is the quantum measurement problem merely a word game?
- Are there any confirmed examples of epiphenomenalism?
- Are the laws of physics applied mathematics?
- Is the wave function objective or subjective?
If you find better examples, don't hesitate to append them / comment. I'm posting my opinion as an answer. If you disagree, please don't downvote this question, but the answer. Or better, post another answer. :-)
(Edit: Added some fictional questions for clarity.)
