The careers of a lot of these scientists are completely wrapped up in one scientific dogma or another, and any discovery that challenges their specific one is understandably met with jealously, rage, etc.

I agree, but I'd call it scientific assumptions rather than dogma. All the scientists involved in this issue seem to be of the non-kook variety, and they know that eventually their assumptions will either be confirmed or overturned by increasingly improved observations of nature.

Most, but not all. There's always Tom Van Flandren and his entourage of groupies.
