QUANTUM GRAVITY- THE EL DORADO – NAY A NE PLUS ULTRA --THE FINAL FINALE

摘要

Motivation for quantizing gravity comes from the remarkable success of the quantum theories of the other three?fundamental interactions, and from experimental evidence suggesting that gravity can be made to show quantum effects?Although some quantum gravity theories such as?string theory?and other?unified field theories?(or 'theories of everything') attempt to unify gravity with the other fundamental forces, others such as?loop quantum gravity?make no such attempt; they simply quantize the gravitational field while keeping it separate from the other forces. Observed physical phenomena can be described well by?quantum mechanics?or?general relativity, without needing both. This can be thought of as due to an extreme separation of mass scales at which they are important. Quantum effects are usually important only for the "very small", that is, for objects no larger than typical?molecules. General relativistic effects, on the other hand, show up mainly for the "very large" bodies such as collapsed?stars. (Planets' gravitational fields, as of 2011, are well-described by?linearised?except for Mercury's?perihelion precession; so strong-field effects—any effects of gravity beyond lowest nonvanishing order in ?/c2—have not been observed even in the gravitational fields of?planets?and?main sequence stars). There is a lack of experimental evidence relating to quantum gravity, and classical physics adequately describes the observed effects of gravity over a range of 50?orders of magnitude of mass, i.e., for masses of objects from about 10?23?to 1030?kg.We present a complete Model which probably explains the positivities and discrepancies and inadequacies of each model. Physics is certainly moving in to the subterranean realm and ceratoid dualism of consciousness and subject object duality(Freud vouchsafed only at the mother’s breast shall the subject and object shall be one),like a maverick trying to transcend the boundaries of space time, standing on the threshold of infinity trying to ponder what lies beyond the veil which separates the scene from unseen?
