A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

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?
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.
