Earlier quoted context omitted.
I like to see it as an as-yet poorly evidenced scientific hypothesis rather than an pseudo-scientific "fact". Which indeed may need to go through further revisions before the correct version is found. But I see lots of circumstantial evidence which makes me think it is worthy of further investigation.
Lots of good fiction feels profound. Good fiction feels right and true. But feeling right does not turn the fiction into science.
I think you'd be surprised at how many scientific breakthroughs have come from individuals being bloody minded about things that everyone else thought were ridiculous. Science isn't just about testing hypothesis. The other part of it is about generating hypothesis to test. That part tends to be a lot more fluffy and subjective, but it's just as critical to the scientific process.
