> Fly to distant galaxies

Unless AI can change the laws of physics, extremely unlikely.

I see, Fly was perhaps the wrong word to use here. Phase-Shift to new galaxies is probably the right term. Where you change your entire system's resonant frequency, to match what exists in the distant galaxy. Less of transportation, and more of a change of focus.

Like the way we can daydream about a galaxy, then snap-back to work. It's the same mechanism, but with enhanced focus you go from not just visualising > feeling > embodying > grounding in the new location.

We do it all the time, however because we require belief that it's possible in order to maintain our location, whenever we question where we are - we're pulled back into the reality that questions things (it's a very Earth centric way of seeing reality)
