By the way, your point is irrelevant as most people including professors don't even care if it is flat or not. They only care about their paychecks.
I would challenge your assumption that most professors only care about their paychecks; they will care for their paychecks to the level you care for yours. Don't assume any moral superiority.
The so-called science is based on memorization of 'known' facts. You memorize the concepts, you get ahead in your career. You challenge the status quo, you get fired and you don't have a job. Pretty easy conspiracy to maintain.
On the contrary: evolution challenged the
status quo, relativity challenged the
status quo, quantum mechanics challenged the
status quo. Barry marshall challenged the
status quo in medicine and received a Nobel prize for it.
Science is frequently challenged by scientists, that is how it progresses.
His attitude towards science and scientists probably explains why Saros works as a part-time cleaner at Walmart. 
I'll let you in to a little secret, the finest human being I have ever known finished his working life as a factory cleaner.
