چکیده
We consider a timelike geodesic congruence in the presence of perturbative quantum fluctuations spacetime metric. calculate change volume bundle geodesics due to such and thereby obtain quantum-gravitationally modified Raychaudhuri equation. Quantum gravity generically increases convergence congruences production caustics.

Derivation of the Raychaudhuri Equation
As a homage to A K Raychaudhuri, I derive in a straightforward way his famous equation and also indicate the problems he was last engaged in. PACS numbers: 04.20.Jb, 04.2.Cv, 98.80 Dr Let us consider a collection of bodies falling freely under their own gravity. They would all attract each other and would tend to converge. If they are expanding or contracting and their gravitational potential e...
متن کاملFluctuations, Gravity, and the Quantum Potential
We show how the quantum potential arises in various ways and trace its connection to quantum fluctuations and Fisher information along with its realization in terms of Weyl curvature. It represents a genuine quantization factor for certain classical systems as well as an expression for quantum matter in gravity theories of Weyl-Dirac type. Many of the facts and examples are extracted from the l...
متن کاملLarge “Dipolar” Vacuum Fluctuations in Quantum Gravity
We study a novel set of gravitational field configurations, called “dipolar zero modes”, which give an exactly null contribution to the Einstein action and are thus candidates to become large fluctuations in the quantized theory. They are generated by static unphysical sources satisfying (up to terms of order G) the simple condition ∫ dxT00(x) = 0. We give two explicit examples of virtual sourc...
متن کاملSingularity: Raychaudhuri Equation once again
I first recount Raychaudhuri’s deep involvement with the singularity problem in general relativity. I then argue that precisely the same situation has arisen today in loop quantum cosmology as obtained when Raychaudhuri discovered his celebrated equation. We thus need a new analogue of the Raychaudhuri equation in quantum gravity. PACS numbers: 04.20.Jb, 04.2.Cv, 98.80 Dr 1 Singularity and AKR ...
متن کاملStress Tensor Fluctuations and Passive Quantum Gravity
The quantum fluctuations of the stress tensor of a quantum field are discussed , as are the resulting spacetime metric fluctuations. Passive quantum gravity is an approximation in which gravity is not directly quantized, but fluctuations of the spacetime geometry are driven by stress tensor fluctuations. We discuss a decomposition of the stress tensor correlation function into three parts, and ...
