Just a Jojo depiction of:

If a Stand has infinite range, could it travel to outer space?
Could a Stand with limited range lift it's user to outer space?
If Koichi made the word "Rocket" on himself, would he be blasted off to space?
If a meteor crashed to Earth, could Josuke fix it to go back to it's original source planet and hitch a ride to that planet?

These are the sorts of questions we need to be asking!
