New Fundamental Theory Reveals Information As The Bedrock of Reality

KentuckyFC (1144503) writes "One of the great problems of quantum mechanics is that physicists disagree over how to interpret it. That’s quite unlike other fundamental theories such as general relativity, which produces remarkable insights into the nature of spacetime that everyone agrees about. The problem is that quantum mechanics is derived using abstract ideas such as Hilbert spaces that have little or no meaning in the real world. Now theoretical physicists have found a completely new set of postulates based on the nature of information and used them for the first time to derive quantum mechanics. The basic postulate is the existence of a fundamental unit of information called a gbit or 'general bit'. Given a sufficient number of gbits, any aspect of the Universe can be encoded and any physical process simulated with a suitably programmed general purpose simulator. In other words, reality is substrate-independent--it’s always possible to reproduce one aspect of the universe perfectly using some other part. The theorists go on to show how a universe that obeys these postulates must be governed by quantum mechanics. So quantum theory and reality at the deepest level must be intimately connected to the nature of information. Something the theorists can agree on at last...maybe!"
