This is the problem. The research for my book Ancient Battle Formations went on for years, and I gradually learned that I had to distrust the prior authorities. There's a fundamental problem with Academia: academics tend to rely on and quote each other which means they can set up vicious circles: an opinion becomes official wisdom which reinforces itself. A consensus can be established by mutually quoting academics that is sometimes - not always, but sometimes - built on the flimsiest evidence. Academics are specialists which means they are familiar with the ground data of their particular field but not with other fields. If the opinions of specialists in other fields contradicts what their own data tells them the pressure is immense to re-interpret that data to conform with the general consensus. This happens more often than you think. Academics of course don't slavishly follow each other. They disagree all the time, but generally the disagreements do not touch on their fundamental assumptions which they hold in common - and which also need to be questioned.
With hard SF all the writer has to do is propose something that isn't obviously wrong - or at least isn't obviously wrong in popular sources like Wikipedia. It's fortunate that writing a novel isn't the same as writing a book for academics.
