No, thats a very, very common misconception (perpetuated by crackpots and picked up on by laymen). Einstein is the typical example of a layman (just a lowly patent clerk) overcoming the dogma of the establishment to revolutionize physics. The reality is quite different: he was an educated, accomplished physicist tackling a well-known problem with the existing theory and his work was quickly seen for what it was: correct.
Newton won a contest to derive gravity. His work was well recieved in his time.
Galileo's work was
not generally well recieved, but there is a reason for that: there were few actual scientists to recieve it! The people who persecuted him all did so on a religious, not scientific basis. Scientists, on the other hand,
did recognize Galileo's work.
The BBT is the logical conclusion arrived at from what was, at the time, a startling discovery.
And as for a conspiracy, the evidence speaks for itself, see:...
Fortunately most scientists are honourable, impartial and objective individuals, but it's easy to see how one can become a little cynical.
Those two sentences contradict each other - and that evidence doesn't in any way imply a vast, global conspiracy (especially in light of the second sentence there...).

In general, they are relatively fast: a good theory stands up on its own in front of good scientists. All of your examples were relatively fast paradigm shifts. It must be remembered that it often takes a decade to
develop a new theory: Relativity, for example was accepted in part (SR) before it was even completed. The Galileo caveat has to be emphasized: his work
was well-recieved by his contemporaries. At 28, he was a university department-head. When he built his telescope and scientists looked through it, they
did comprehend what they saw.
The problem was simply that very few laymen knew anything at all of science (since it was in its infancy) and then there was the Catholic church... I cannot emphasize enough that the people who persecuted Galileo
were not scientists.

He needs to learn some basic geometry. The BBT does, in fact make every point in the universe look to itself like its at the center of the universe.
