Respectfully, turning to an 'interdimensional' hypothesis seems unneccessary and doesn't really add anything to the discussion.
While there are possibly up to 11 dimensions (or more) in the universe, they are not accessible to us, being 'wrapped up in the miniscule fabric of
space' is what I've heard them described as. Currently, we travel around by our version of the steam train (rocket ships) but if we had more energy
available to us, we could bend space to create short-cuts through space or speed our ships up to close to the speed of light.
The nature of our universe will not change from one side to the other, what does change is our technology and energy levels to literally bend space to
our will. Michio Ikaku's books give a good run down on this. There are a number of different ways to effect anti-gravity type flight in current
physics theories, using what to us is exotic like gravitons and anti-matter etc but may not be particularly exotic where this material is readily
available or can be created and stored by advanced technology.
There are theories of multiple universes, but one would think they if something visits our universe, they still need to adapt to our physical laws,
and it seems unneccessary, because there should be plenty of life moving around in our neighbourhood from our universe. There are possibly trillions
of planets in our universe.
Basically, if you saw a metallic looking shiny spaceship...it's probably a metal shiny spaceship..powered by better technology than we have, that's
