I want to know the answer to the following question:
Who was the author of Conversations on the Plurality of Worlds (1686)?
All the background I'm provided with is that "The first significant work that expressed scientific theory and knowledge expressly for the laity, in the vernacular, and with the entertainment of readers in mind, was Bernard de Fontenelle's Conversations on the Plurality of Worlds (1686).". Is that enough to answer the question?
Answer: yes
