In Peter Pan, what if Neverland means that the entire place is of people never landing? See, Einstein theorized that the faster one moves, the slower time passes for them, though from their perspective, it seems like time is still moving at a normal pace. In order to move through time without aging, one would have to move at the speed of light. So what if flying to the second star to the right is accelerating to just under the speed of light, and Neverland is just a plane over our own where everyone moves at the speed of light, or so fast that we cannot see them, and what they do does not affect us. It would also explain why Peter comes back at the end of the story thinking hardly any time has passed, but Wendy is an adult now. Just a thought.
