Does a photo show Elon Musk reading a book titled "The Flat-Earth Conspiracy"? No, that's not true: The image in the post has been digitally altered. The photo, which originated from another author's official social media page, displays Musk reading a book with a different cover and title.

The original photo of Musk reading a book shows the cover of "The Dinosaur Hunter." A reverse image search produced a November 22, 2010, Facebook post from the official account of Homer Hickam, the author of "The Dinosaur Hunter." That's where the image of Musk reading Hickam's book originated.
As seen in the Facebook caption below, Hickam thanks Musk for promoting his book, which is about a cowboy/ex-cop who discovers dinosaur fossils beneath the Earth's surface on Montana farmlands -- not about a conspiracy theory that the Earth is flat.
