NON-COMPUTABILITY. “A random real number is (with probability 1) uncomputable — as follows from simple cardinality arguments. Some proponents of ‘hyper-computation’ consider this is a key fact leading towards their goal.” https://lnkd.in/eu3iHYtJ View in LinkedIn

EXPANDING UNIVERSE. “In this scenario, both the late and the early cosmic accelerations have their origins in spacetime foam.” https://lnkd.in/eA85pA5X View in LinkedIn

TURBULENT AND LAMINAR FLOW. “Furthermore we use the deep similarities between turbulence and the spacetime foam phase of strong quantum gravity to argue that the early universe was in a turbulent regime when it underwent a brief cosmic inflation with a “graceful” transition to a laminar regime.” https://lnkd.in/eA85pA5X View in LinkedIn

IMPLICATIONS. “Applied to cosmology, the holographic foam model predicts the existence of dark energy with critical energy density in the current (late) universe, the quanta of which obey infinite statistics.” https://lnkd.in/eA85pA5X View in LinkedIn

QUANTUM FOAM. “Quantum fluctuations endow spacetime with a foamy texture. The degree of foaminess is dictated by blackhole physics to be of the holographic type.” https://lnkd.in/eA85pA5X View in LinkedIn

“BIOLOGICAL roulettes and of chance they generate. They are at the same time products and engines of the evolution. Without them, life would have disappeared from the Earth a long time ago.” https://lnkd.in/eEFbgDqX View in LinkedIn

THIS POSTING of this very difficult and long paper was probably a one-of-a-kind for me, based on the truly extraordinary nature of this article. More than almost any other that I have read in quantum physics, it goes to great pains to explain in words the rational behind each of the steps in this enquiry. A true masterpiece! https://lnkd.in/eiqmZcSk View in LinkedIn

EVERYTHING COMPUTES. “The Californian philosopher John Searle argues that even your garden wall is a conventional computer; and other philosophers maintain that a simple rock standing motionless on a beach is a (conventional) computer.” https://lnkd.in/eepengBW View in LinkedIn
