Who discovered theory of the universe was held as law for thousands of years even though you were wrong?

The question seems poorly phrased, but perhaps you are referring to Aristotle.

Aristotle had opinions about EVERYTHING, widely voiced his opinions, and was entirely wrong in almost every particular. In fact, Aristotle may be the wrong-est man to ever live. Millions of needless early deaths were caused by his laughably incorrect medical teachings, which stulted the field of medicine for over 1500 years. His astronomy was wrong, his physics were idiotic, and his chemistry was below the level of "juvenile".
