I needed to figure how dimension hopping could work. Just saying it happens is not enough for me as a writer or a reader. Call me old fashion but it's what I grew up reading. Larry Niven, Arthur C. Clark, and Issac Asimov always made their science believable.
This gave me credibility for when I write about the shift to another dimension. My character doesn't go into detail like this guy did but at least it will be believable and not within the category of 'science so advance it's in the realm of magic.' I love a story that has a foot in fiction and the other foot in reality.
