The word “supernatural” is a nonsensical category.
People used to think lightning was supernatural, caused by sky gods flinging weapons at each other. Then we figured out a natural explanation and now we don’t.
People used to think diseases were caused by supernatural demons. Now we know they’re caused by germs.
People used to think the stars, moon, sun, planets, and meteors were gods and various spirits. Now we know what they are so there’s nothing supernatural about them.
Throughout history, “supernatural” has simply meant “ignorance.” It is always a temporary category, a placeholder until we figure out what’s really going on.
So why bother? I mean, we don’t know all kinds of things. We don’t know what the hell happens inside black holes, but we’re trying to figure it out. But why would anyone say that “supernatural magic” happens inside black holes?
