Search for Quantum Gravity
A satisfactory theory of quantum gravity may necessitate a drastic modification of our perception of space-time, by giving it a foamy structure at distances comparable to the Planck length. It is argued in this essay that the experimental detection of such structures may be a realistic possibility in the foreseeable future. After a brief review of different theoretical approaches to quantum gra...
متن کاملPerturbative Quantum Gravity in Analogy with Fermi Theory of Weak Interactions using Bosonic Tensor Fields
In this paper we work in perturbative Quantum Gravity and we introduce a new effective model for gravity. Expanding the Einstein-Hilbert Lagrangian in graviton field powers we have an infinite number of terms. In this paper we study the possibility of an interpretation of more than three graviton interacting vertices as effective vertices of a most fundamental theory that contain tensor fields ...
متن کاملGauge/Gravity Correspondence and QCD
String theory has experienced a revolutionary period since around 1995. One of the most important discovery is the D-brane. It has opened up profound relationship between string theory and quantum field theory. Now we have come to the stage to consider realistic physics by applying the techniques developed in string theory to QCD. The purpose of this note is to provide a brief overview on the a...
متن کاملGeneralizing Quantum Mechanics for Quantum Gravity
How do our ideas about quantum mechanics affect our understanding of spacetime? This familiar question leads to quantum gravity. This talk addressed a complementary question: How do our ideas about spacetime affect our understanding of quantum mechanics? Familiar non-relativistic quantum theory illustrates how quantum mechanics incorporates assumptions about spacetime. The Schrödinger equation ...
متن کاملPerturbative Gravity from QCD Amplitudes
We demonstrate that QCD gluon amplitudes can be used to construct a Lagrangian for gravity. This procedure makes use of perturbative ‘squaring’ relations between gravity and gauge theory that follow from string theory. We explicitly carry out the construction for up to five-point interactions and discuss a set of field variables in the Einstein-Hilbert Lagrangian for interpreting the Lagrangian...
