REALITY. “Following Wheeler, we believe that space is composed of an ever-changing geometry and topology called spacetime foam and that the foaminess is due to quantum fluctuations of spacetime. We argue for a scenario in which spacetime foam is the origin of both cosmic accelerations.” https://lnkd.in/eA85pA5X View in LinkedIn

HEISENBERG. “One manifestation of spacetime fluctuations is in the induced uncertainties in any distance measurement.” https://lnkd.in/eA85pA5X View in LinkedIn

FOOTNOTE. “Henceforth we will neglect multiplicative constants of order unity.” https://lnkd.in/eA85pA5X View in LinkedIn

HYPOTHESIS. “We can now give a heuristic argument on why the Universe cannot contain ordinary matter only.” https://lnkd.in/eA85pA5X 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

The unique and extraordinary, absolutely spine-tingling, Sagrada Familia by Antoni Gaudí in Barcelona, once considered a madman and who died mistaken for a beggar on the street after being hit by a tram. View in LinkedIn

FRAGMENT FROM NATURE features an intriguing article by Professor Robert Arnott Wilson, who is the retired Emeritus Professor of Pure Mathematics at " "Queen Mary University of London, about his contrarian ideas for a new unifying theory of physics. He was educated at Trinity College Cambridge from his undergraduate degree through to his PhD. https://lnkd.in/egNPUiXr View in LinkedIn

QUANTUM UNDERPINNINGS. “The physical theory of the very small is based on quantum mechanics, which is a very successful theory that underpins almost all of modern technology. The physical theory of the very big is based on general relativity, which is a very successful theory that underpins our understanding of the universe and our place within it, and is also an essential ingredient in modern technology such as GPS.” https://lnkd.in/e-atRRat View in LinkedIn

TWO WORLDS. “There is only one problem—these two theories are incompatible with each other. This problem has been known since the 1930s but we seem to be nowhere near a solution yet.” https://lnkd.in/e-atRRat View in LinkedIn

EXCESSIVE SUCCESS. “Part of the reason for this is that the two theories have been almost too successful. By the 1970s, quantum mechanics had developed into the ‘standard model of particle physics’ which explains almost everything about the elementary particles of which the universe is made. Almost every experiment has confirmed the model in almost every detail, culminating in the discovery of the Higgs boson in 2012.” https://lnkd.in/e-atRRat View in LinkedIn
