on teleportation

Well I thought I was going to sleep but it turns out I just needed to have a three hour mostly-eyes-closed think.

Not the primary part of the think, but I think I have reasonably solved (to my satisfaction) the puzzle of teleportation.

I have spent many years mulling on the physics of the problem, figuring the answer would be along the lines of "most matter is actually space, and that is why monks could walk through walls" or "time actually exists all at once, and so time travel will mostly be a matter of learning to comprehend that truth" ... but then with that latter one comes the problem of time-space: presuming we want to time-travel and end up somewhere on the planet earth (and not, for instance, in the void of space between galaxies), one would also need to comprehend also and compensate for -- quite exactly if one wanted to actually arrive on or very close to the surface of the planet -- the insanely fast motion of the planet (and the solar system, and the galaxy) through space.

And there is the problem, as a person travelling to a new space-time where quite a bit of matter already exists, of what happens to that matter, which is not going to happily co-exist with all the new matter the person is manifesting there-then.

This problem of time-space shift of course also applies to teleportation-by-intuitive-grasp-of-the-physics.  Pretty tricky to not end up in space, real problem of what happens to the displaced matter (/which matter ends up displaced and how painful is that for the matter involved).   It's actually somewhat easier, presuming this mathematical-comprehension problem is the path to a workable solution for teleportation, to move a planet into orbit around another star -- one could theoretically work out where there was likely to be little or no space dust in the proposed new orbit -- than to move a person around "on earth."

So tonight it occurs to me that the primary problems could be solved if astral-projection/out of body experiences are a real thing (which I think they are).  Of course the normal situation is that one's mind/spirit leaves the body, either on purpose or by trauma, wanders about for some bit for whatever set of reasons, and then comes back and flows back into the body -- at least in all the cases where the person comes back to tell us about it.  Some people have cultivated a skill in this.  Some surprising-to-me people have had uncontrolled (trauma-induced) out-of-body experiences.  I don't recall ever playing this game this way myself, except once when it started to slip out and I was like "HEY" and scrabbled it back in, so I have some decent initial instinctual skills or control but am not speaking as some sort of expert.

Anyhow, I think it would be interesting if the actual key to teleportation was about astral-projection traveling to where you wanted to go, and then rejoining your body to your mind/spirit, instead of rejoining your mind/spirit to your body.  It would require some of the same mind-bend that the physics solutions to traveling or walking through solid objects require (one has to fully commit to "physical reality" being just math and energy-states, not "material" in any fundamental sense -- "there is no spoon" and all that).  

This solves the ends-up-in-space and impossible-level-of-precision problems.  And it solves the equally important problems of making sure the body arrives on (or very close to at least) the ground and in clear air (not in space already occupied by a wall, or a tree, or a person, for instance).

It doesn't really solve the matter-already-exists-here problem, and it doesn't make sense that the air would magically exchange places to where you were, since the air can't astral-project itself and in any case has no reason to know where you came from, so one might still die a very messy death, but perhaps the body would show up in some sort of expands-into-reality manner that pushes the air aside ... locally loud, no doubt (interesting that Rowling included the noise in the Harry Potter series), but (presuming it displaced instead of creating a physics paradox) the air pressure change for the volume of one person leaving or arriving would be fairly minimal in terms of damage at point of departure or arrival.

I suppose if one also mastered walking through walls, one might apparate to someplace, air-included, and then move the air out of one's body-space, like a reverse of walking through a wall.  Walk the wall out of oneself.  Same reversal-of-beliefs/understandings as the teleportation proposal, actually, just hold "reality" to be the other side of the coin from what we have been taught to believe.

Anyhow I'm fairly pleased with solving the logic of not ending up in outer space and it being an intuitive process instead of one that requires 15 supercomputers and probably still wouldn't drop a white mouse within 2000 miles of where it was meant to appear.

I have been pretty sure for a long time now that if humans ever achieve time travel or teleportation, it will be by intuitive motion through time-space and not by machine.
