Invention of Gravity
The last thing the commenter has to argue about in this photo is whether or not Newton invented or discovered gravity. In this shot, we can see many wrong things, some of which have nothing to do with gravity! A great deal of it has nothing to do with the lightbulbs, either. This is another instance where we can’t decide which is more ridiculous – the original post or the comment.
Let’s start with computers that weren’t even created until 1822, which is well after the invention of gravity in 1687. Or how about a bit of guy changing what looks like a vent rather than a lightbulb while flying over the heads of his seated students? So many things are wrong with this photograph.
