The problem is all the easy problems have been solved, and even all the hard problems have been solved in science. We're down to the really hard problems, and since our otherwise astoundingly accurate observations of how the universe acts are thrown off by them, everything looks weird and fringe at the very hard edges.

The vast majority of “fringe” stuff comes from people who don’t really understand the standard model or modern consensus. It consists of half-baked ideas that don’t hold up to passing scrutiny by those who understand the field. Not because of any bias… but because the ideas have glaring flaws, don’t explain existing observations well, or are mostly incoherent.

Science is hard, and it takes a lot of work.

I’m guessing this is what the parent comment was referencing.
