Most of the time writers just don&#x27;t care about researching what they are writing about - this is not limited to sci-fi. Whenever a writer does any sort of research it&#x27;s magnificent - see: The Martian. With knowledge readily available and basic facts easy to establish within seconds there is really no excuse.<p>I have to admit I&#x27;ve never dropped a book because of that so maybe writer&#x27;s know they don&#x27;t have to do it.
