This. The institution of science is deeply biased towards the established knowledge base - partly due to monetary interests, partly due to 'simple' social inertia, like when someone doesn't want some kid to come up with ideas that may invalidate things they have seen to (seem to) work.

Like with magnetohydrodynamics - it's useful for modeling some things, but depends on the notion that space (as in, the interplanetary and interstellar medium) is either nonconductive or infinitely conductive - which simply isn't the case.

Plasma cosmologists have made some really nutty assertions. However, ideas should be treated on their merit - and some of what they theorize has a lot of solidity. But in general, it's treated with derision, because (admittedly) it also traffics in unicorns.

If someone who purports to traffic in unicorns also traffics in the Principia Mathematica, it doesn't invalidate the latter.
