Their minds are too conditioned. Being overly educated is a huge disadvantage when the root assumptions are being re-written/replace/removed. This is mainly due to the mind not being able to build structure because the root assumptions are too ingrained. Think about it as an analogy.
Picture the dogma as a large tree, and the assumptions as its roots. If you remove the assumptions the tree falls over and dies. They literally can't remove their root assumptions, because they give structure and strength to everything they do. When the root assumption is removed, such as planets being older/dead/evolving stars, then every theory and idea that is based on that dies. That is essentially 95% of all astrophysics. Right there. Based on a single root assumption that keeps the entire tree upright.
The root assumption is that planets and stars are mutually exclusive objects, that is what gives "credibility" to literally all astrophysicists. If that is wrong, then their degrees, worldviews, meetings, awards, paychecks, livelihoods are all thrown into a deep crevasse full of lava, along with Elmo. Sorry bro.
It is also a Chinese proverb as well. "When reading, don’t let a single word escape your attention; one word may be worth a thousand pieces of gold." 读书须用意，一字值千金 Meaning, "Reading must be intentional".
Astrophysicists read to memorize and recite and "get along" so they can move to the next steps and get larger and larger paychecks and job security. They have never had the intention to understand or question assumptions, their intention was to fit in and gain a feeling of importance, job security, sense of belongingness, etc.
When astrophysicists start school, they already begin on the wrong foot, they do not read with intention, therefore they miss the GOLD. Planet literally means "wandering star". It has been right in front of them the whole damn time, since the ancient Greeks themselves. That's exactly what a star is, a young, hot, exoplanet or "planet".
