The Universe of Fluctuations: The Architecture of Spacetime and the Universe (Fundamental Theories of Physics (147))

**The Universe of Fluctuations: The Architecture of Spacetime and the Universe is a path-breaking work which proposes solutions to the impasse and crisis facing fundamental physics and cosmology. It describes a cosmological model based on fuzzy spacetime that has correctly predicted a dark-energy-driven acceleration of our expanding universe - with a small cosmological constant - at a time when the popular belief was quite the contrary. It describes how the Universe is made up of an underpinning of Planck oscillators in a Quantum Vacuum. This leads to, amongst other things, a characterization of gravitation as being distributional over the entire Universe, thereby providing an answer to a puzzle brought to light by Weinberg years ago and since overlooked. There is also a simple formula for the mass spectrum of all known elementary particles, based on QCD dynamics. Many other interesting ramifications and experimental tests for the future are also discussed. This apart, there is a brief survey of some of the existing theories. The book is accessible to junior and senior researchers in High Energy Physics and Cosmology as well as the serious graduate student in Physics.** In 1997, contrary to the ruling paradigm which was that of a dark matter ?lled, decelerating universe, my work pointed to a dark energydriven- celerating universe with a small cosmological constant. Moreover, the many supposedly accidental Large Number relations in cosmology, including the mysterious Weinbergformula were now deduced from the theory.

The 1997, and subsequent work was the consequence of mainly three cons- dark energy or the well known Zero Point Field, fuzzy spacetime and ?uctuations. Indeed String Theory and Quantum Gravity approaches have had to discard the smooth spacetime of General Relativity and Qu- tum Field Theory, in a quest for a uni?ed description of these two pillars of twentieth century physics. This book is the result of some seventy ?ve papers published in international journals,andpartlyanearlierbook," to the Hubble Scale" (Nova Science, New York, 2001), as also several lectures delivered in Universities and institutes in the United States, Canada and - rope. It describes how, in a simple and somewhat conventional framework, an underpinning of Planck scale oscillators in the ubiquitous Zero Point Field or dark energy leads to a uni?ed description of phenomena involving elementary particles and the cosmos. In particular, apart from the cosmology mentioned above, these considerations lead to a uni?ed description of all interactions, includinggravitation, thoughinanextended gauge ?eld treatment. The failure of all attempts to unify gravitation with other fundamental interactions has led to an abandonment of point particles and differentiable spacetime of General Relativity and Quantum Theory, including Quantum Field Theory. While Quantum Superstrings (or M-Theory) and other Quantum Gravity approaches work with a lattice-like structure or extended objects, several unanswered questions remain. The book describes another approach in which oscillators at the Planck scale from a background Quantum Vacuum are fundamental. We describe how this leads to the formation of the elementary particles, and also a cosmology that correctly predicted an accelerating Universe with a small cosmological constant, apart from other things. In this context the nature of spacetime and gravitation are reexamined. While it is argued that spacetime has a chaotic underpinning on the one hand, gravitation has a distributional character on the other. It is shown how all these considerations are not only considerations are not only consistent but also explain several, otherwise unanswered features The failure of all attempts to unify gravitation with other fundamental interactions has lead to an abandonment of point particles and differentiable spacetime of General Relativity and Quantum Theory, including Quantum Field Theory.
