First one that got me was the black hole. If I dig a hole in the ground, is that not really a hole? If I find a hole in your logic is that not a hole? If I model the flow of charge with positive ‘holes’ between electrons, are they not holes? And… do people really commonly think a ‘black hole’ is a traditional sort of hole? ‘Hole’ seems a perfectly reasonable name for what it really is.

Now what a black hole really is is fascinating stuff, but not in a “see, people are so ignorant to think it’s a hole” kind of way.
