GUT's in curved spacetime: Running gravitational constants, Newtonian potential, and the quantum-corrected gravitational equations.
The running coupling constants (in particular, the gravitational one) are studied in asymptotically free GUTs and in finite GUTs in curved spacetime, with explicit examples. The running gravitational coupling is used to calculate the leading quantum GUT corrections to the Newtonian potential, which turn out to be of logarithmic form in asymptotically free GUTs. A comparison with the effective t...
متن کاملString Cosmology and the Dimension of Spacetime
The implications of string theory for understanding the dimension of uncompactified spacetime are investigated. Using recent ideas in string cosmology, a new model is proposed to explain why three spatial dimensions grew large. Unlike the original work of Brandenberger and Vafa, this paradigm uses the theory of random walks. A computer model is developed to test the implications of this new app...
متن کاملGravitational collapse and spacetime singularities
The nature of gravitational collapse was the subject of debate and controversy for much of the last century. During the 1960’s and 1970’s our understanding of general relativity consolidated and culminated in our modern understanding of black holes and spacetime singularities. Since then, there has been significant advances in understanding the dynamics of gravitational collapse and the nature ...
متن کاملGravitational Waves from Warped Spacetime
We argue that the RSI model can provide a strong signature in gravitational waves. This signal is a relic stochastic background generated during the cosmological phase transition from an AdS-Schwarschild phase to the RS1 geometry that should occur at a temperature in the TeV range. We estimate the amplitude of the signal in terms of the parameters of the potential stabilizing the radion and sho...
متن کاملOn the detectability of quantum spacetime foam with gravitational-wave interferometers
We discuss a recent provocative suggestion by Amelino-Camelia and others that classical spacetime may break down into “quantum foam” on distance scales many orders of magnitude larger than the Planck length, leading to effects which could be detected using large gravitational wave interferometers. This suggestion is based on a quantum uncertainty limit obtained by Wigner using a quantum clock i...
