On quantization of gravity
The theory of gravity without free gravitational fields is considered. It is assumed that gravitational radiation is some hypothetical matter fields. Gravitational emission is a process of the decay of proton into hypothetical matter fields at the Planck scale. In the Einstein theory of gravity [1] with the Lagrangian L = − 1 16πG √ gR, (1) gravitational field is defined by the components of th...
متن کاملDualities and Emergent Gravity: Gauge/Gravity Duality
In this paper I develop a framework for relating dualities and emergence: two notions that are close to each other but also exclude one another. I adopt the conception of duality as ‘isomorphism’, from the physics literature, cashing it out in terms of three conditions. These three conditions prompt two conceptually different ways in which a duality can be modified to make room for emergence; a...
متن کاملTowards Noncommutative Quantization of Gravity
We propose a mathematical structure, based on a noncommutative geometry, which combines essential aspects of general relativity with those of quantum mechanics, and leads to correct “limiting cases” of both these physical theories. We (algebraically) quantize a groupoid constructed on space-time rather than space-time itself. Both space and time emerge in the transition process to the commutati...
متن کاملThe Perturbative Quantization of Gravity
A suggestion is made for quantizing gravity perturbatively, and is illustrated for the example of a massive scalar field with gravity. 1 The Scheme This short talk is about the renormalizability of Einstein gravity1. It is NOT renormalizable so this might indeed be a very short talk! However the work might best be viewed as a look back over failed campaigns of the past. We are forever rushing a...
متن کاملTriplectic Quantization of W2 gravity
The role of one loop order corrections in the triplectic quantization is discussed in the case of W2 theory. This model illustrates the presence of anomalies and Wess Zumino terms in this quantization scheme where extended BRST invariance is represented in a completely anticanonical form.
