Mass distorts spacetime, which to an outside observer appears to change the direction light travels. The light travels in a straight line.
Gravity doesn’t alter the particle’s trajectory (or ours, for that matter). The warping of spacetime from Earth’s mass causes our movement through space to accelerate “down” at ~9.8 m/s^2
So the ghosts are in the center of the Earth, in nearly literal hell.
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?
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.
Well that’s just a theory, albeit good, and there’s a good chunk of modern science that refuses to marry it, so let’s not be too sure about it, shall we?
Although general relativity is highly regarded for its elegance and accuracy it is not without limitations: the gravitational singularities inside of black holes, the ad hoc postulation of dark matter, as well as dark energy and its relation to the cosmological constant are among the current unsolved mysteries regarding gravity; all of which signal the collapse of the general theory of relativity at different scales and highlight the need for a gravitational theory that goes into the quantum realm.
I really hate that people just accept these advanced theories as objective truth. It’s just the best theory we have right now, that doesn’t mean that’s how it actually works. It’s good enough that we can almost always just use the theory and get good results, but then people get all pissy when you point out that it’s still just a theory and is not without its flaws.
Massless light is still affected by gravity, though…

It is straight in reference to the distorted spacetime.

But light isn’t a particle it’s a wave. I mean, just look at it… Oh… Forget it. It’s a particle.
It’s neither a particle nor a wave, it’s a photon.
A zebra is neither a horse nor a tiger, though it shares properties with both.
It was a joke – it behaves as a wave until you observe it; then it collapses into a particle.
