Such technology cannot be used to transfer living technological bodies to higher frequency physical realities, as when reaching there the matter does not consists from protons electrons and neutrons, and the living body, takes a completely different immateriality, with different finer particles (and periodic system)., due to an ability of the living life to hold together inherited by the spiritual origin of life. But technological objects from protons electrons and neutrons do not have this spiritual property as life does. A migration to a higher frequency physical reality is possible only for the living bodies not the inorganic and technological, and it requires that the consciousness and mind of the living body, has sufficient high quality principles , so that also the frequency of the living aether sub-bodies of the living body have also higher frequency, so that life can go on when reaching the higher frequency physical reality. In the traditional metaphysics this is called migration due to initiation and is a long transformation processes of the consciousness of the individual. This migration atomic or collective is the standard direction of evolution of life, in other words it is the mystic "return" to its higher realms closer to its spiritual origin and creation.
Besides this travelling by pairs of field gates which is in the technological reach of the current galactic civilizations there is also another almost instantaneous traveling of similar nature but by far more difficult construction which is the "galactic highways" There are 17 "highways" of travelling through "Gates", in this galaxy, made most probably by the first and Founders of living biospheres (those that for the first time by lowering the frequency of the spin of the matter of the living life that pre-existed and pre-created by higher spiritual creators , in higher frequency invisible realities made life appear for the first time in our visible physical reality) . But due to the galaxy expansion, many of them have snapped, and only 2 still function. The current living civilizations in the 3rd density do not know how to repair them. It is speculated that "The Founders" that created the fist living biospheres new how to, and created the travelling "Highways" that helped them too initiate living planetary biospheres. Most probably it was "The Founders" who have created also the found in galactic archaeology, devices, that create 3rd density matter (probably through 3rd density anti-matter and not only) and appropriate information programming for this. Modern galactic travelling is also to other galaxies. Our solar system is at the outer "suburbs" of our galaxy, and an old idea was to make it a center of information exchange of extra-galactic travelling.
