I am in the process of reading “The Black Hole Wars” by Leonard Susskind. This contains one of the best explanations as to why the universe may be, at its core, simply made up of digital information similar to a huge hologram that I have read. Indeed, this is, together with Vlatko Vedral’s “Decoding Reality”, the best “companion volumes” that will help readers of the last chapter of my forthcoming book, “Opening The Doors of Perception”, appreciate the point I am trying to make.
