Good day. I'm sure you already know about the parrallel diamention theory. If you don't, then it's basically about there being an infinate number of parrallel universes, each with an infinate number of changes. Becaus of this, there is bound to be an infinate number of universes with technology that has reached every possible limitation. So if inter-diamentional transportation were possible, an infinate number of universes would already have travelled into our universe. Since our universe has not yet been destroyed by an infinate number of inter-diamntional tourists, I don't think that inter-diamentional transportation is possible.
