>>655422Basically there's some weird shit we can't explain. Not just light, but big ass molecules can act as particles and waves. We have ample evidence of this. What the anon is saying is that one of the proposals to explain such phenomena has been the mutliverse theory. There's no evidence that this theory is correct. It's just a proposal.
There's woo woo spiritual new age peddlers that use whatever thing science is pushing out, such as this purely theoretical proposal. Usually completely misunderstanding the actual science behind it.
Things like quantum medicine are a thing for example.
