What was the most 'revolutionary' scientific theory of all time?

I agree. Copernicus. Theology ruled that day so his theory was especially controversial.

Evolution has certainly been good for controversy in more modern time, but it's well accepted and has been from the get go. Darwin and Wallace never were under house arrest and had to pretend they diedn't believe what they believed.

Quantum theory sure made things strange (unintentional pun), but I don't see it being as revolutinary as Copernicus's theories.
