One other possibility to consider: every piece of ‘matter’ in the universe is not merely an object in a location. Rather (this is a big leap), LOCATION (x,y,z) is a ‘vibrational property’ of each object. Such vibrational properties are not yet acknowledged by present day physics.
Darryl Anka channels the ET named ‘Bashar’. Bashar states that their ships create a ‘field’ around the ship, that allows it to uncouple the current vibrational locational variable of the ship. And then reinsert a new locational variable. The result: the ship ceases to exist in location A, and now appears in location B. Without traveling through the intervening space. No wormholes involved.
Could send you the book by Anka with a longer more detailed description of this technology.
