This to build the creation machine:

Basically the empty space is simply cobntinuous "creation" of matter+antimatter couple of particles that exist and annihilate (destroy in couples) continuously, so you see nothing. If you can avoid them to collide and annihilate, so if you kick one of the 2 for example to go away, these matter pieces would theorically keep in existence since not annihilated as normally planned by quantum theory. There are a few dimensions so I am unsure we can talk of creation, could be simply they change dimension so creation and annihilation is relative to this our dimension only, but what we do know? Very little.
