" Researchers still don’t know what’s involved in Shifting. Have you heard of dark matter?’
‘I know the name but not what it is.’
‘It’s something like another dimension all around us. We can’t see it or touch it, but there’s five times more of it than what we call our world. It isn’t made of atoms in the way that we are. It’s at the edge of our understanding of the universe. It’s like black holes – you can’t view them, but you know they’re there because of the way things act when they’re in close proximity to one. It’s the same with dark matter. We think teleportation involves a dimensional shift.’
