I couldn't agree more. I don't think anyone should claim to be certain about any of our understanding of the universe. I just say that it isn't very useful to think that way, we make more progress if we have the courage to trust in a theory and dare to be proven wrong, than to go back to the drawing board when we get stuck.

For uncertain things, as long as the courage extends to all feasible (meaning, not outright disproven like flat-earth…) models then we’re in agreement.

What bothers me generally, is how one speculative theory dwarfs others when the scientists themselves will admit that there’s far more wiggle-room.

This has implications in funding and brainpower, hindering progress in the long run.

Yes, in case someone asks: The contrarian side where alt-theories include the outright disproven is also worrisome; but in HN at least everyone seems pretty bright and attentive to good science; far smarter than yours truly, certainly.
