What are all the ghost rules?
If a person becomes a ghost,

Can they fly off into outer space?
If I am a ghost, I want to go see the moon.
I can pass through physical objects, right?
I’m not constrained by natural physics as we observe them normally, right?
Like, the whole thing about passing through walls and stuff.
So, I’m flying off to the moon.
How fast can I go?
Can I just kinda teleport there?

To do that, wouldn’t I need to be omniscient?

I hope I won’t be omnisicient.
That’s way too many things to know.

Let’s assume some kind of travel speed.
I wonder what it would feel like to just pick a star and head in that direction for a few million years or however long it takes to get there.
Better pick a good one! It’s gonna be a long trip. But I can do it!
I am a ghost.

Where are all the animal ghosts?
