If the spacetime is distorted, and the light no longer appears to travel in a straight line, does that not mean that spacetime itself and the light that travels in are no longer straight?

How can a straight thing be distorted but still be straight?

I think a better way of explaining it is with the idea of a shortest path, and not nessesarily a straight line. With two points in space the shortest path between them will be a straight line. If there’s a large amount of gravity tugging on space time the shortest path will be curved.

That's called General Relativity and Reference Frames.

Start watching PBS Spacetime if you actually want to get into it.

You're also entirely missing the point of the comment that was a joke entirely re-explaining the "reason" for ghosts ending up at the center of the Earth, which is implied by the original comment.
