In The Cosmic Computer I have suggested that the Universe consists of tw0 domains of information, each Fourier dual to the other, and separated in the dimension of pure scale at the level of atoms. The fact that the math of Fourier transforms that is a mainstay of information processing

Quantum information theory has now allowed physicists to solve the 50 year old black hole information paradox. When a black hole emits Hawking radiation, the emitted particle is entangled with its partner particle that gets sucked into the black hole, so what happens to all the information carried by the

Phase The word phase is used in many different ways in physics, but just think of it here as the angle that the hand of a clock makes to the 12 o'clock position. In quantum computing, one phase normally means one complete cycle which is 360 degrees or

Causal Set Theory is based on two data domains: first, the causal set of discrete points where events can occur in spacetime; second, second, the connection data of all the causal relations between events.  This is a natural match with the Cosmic Computer view that atoms are where all events

I only recently discovered the ER paper that gave birth to the Einstein-Rosen bridge thanks to this recent article in Quanta magazine by Natalie Wolchover, and it fits extremely well into the scheme of The Cosmic Computer, like a missing link. Einstein’s general theory of relativity has holes in

This is the subject of this video by PBS Spacetime: https://www.youtube.com/watch?v=F__elfR3w8c&t=3s I think PBS Spacetime is one of the best channels for trying to understand physics – excellent graphics and everything well explained. As a subscriber, I have posted this comment

Does quantum mechanics allow 'hidden variables' to decide quantum outcomes, fine-tuning the emergence and evolution of the outer world? While several 'no-go' theorems have ruled out any possibility of local hidden variables playing a part in quantum decision making, the way is still open for global

The 2013 paper Quantum States as Ordinary Information by Ken Wharton offers a new, and realistic, way of understanding quantum mechanics. It also fits very neatly into the dual inner and outer domains picture of The Cosmic Computer, where each domain has its own reference system – spatial coordinates for the

How do our silicon chips compare with Nature's processing? The Margolus-Levitin value for the natural processing rate in matter is 5 x 1050 logic operations per second per kilogram, and the silicon in a typical chip weighs about 2 x 10-3 kg (2 gm), so the natural processing
