What is the author's style in How to Live Safely in a Science Fictional Universe: A Novel by Charles Yu?

Word choice is central to the inventiveness of this story. The author concocts jargon and theories that sound scientific in a tongue-in-cheek way, which help a narrative to emerge that has the trappings of a plausible world of the future. The science in this book certainly would not stand up to scrutiny by, say, a physicist, but the language is playful and the tone humorous, signaling that no such claims to "authenticity" are being made by the author. Instead, the language is a device for immersion into strange worlds separated not so much by physical distances as by time.
