Controversial in example sentence
Godwin's book, "The Man in the Moone, or a Discourse of a Voyage Thither," was only published posthumously and anonymously in 1638, likely on account of the number of controversial ideas that it contained, including an endorsement of the Copernican view of the universe that put the Sun at the center of the Solar System, as well as a pre-Newtonian concept of gravity that had the idea that the weight of an object would decrease with increasing distance from Earth.
