One-loop quantum gravity repulsion in the early Universe
One-loop quantum gravity the early Universe
2010/12/27
Perturbative quantum gravity is used to compute the lowest order corrections to the classical spatially flat cosmological FLRW solution (for the radiation). The presented approach is analogous to the...

Perturbative quantum gravity is used to compute the lowest order corrections to the classical
spatially flat cosmological FLRW solution (for the radiation). The presented approach is analogous to the...
In this article we review the foundations and the present status of loop quantum gravity. It is short and relatively non-technical, the emphasis is on the ideas, and the flavor of the techniques. In p...
We apply a recent argument of Verlinde to loop quantum gravity, to conclude that Newton's law of gravity emerges in an appropriate limit and setting. This is possible because the relationship between ...
The questions I have been asked during the 5th International School on Field Theory and Gravitation, have compelled me to give an account of the premises that I consider important for a beginner's app...
We calculate modifications to the Schwarzschild solution by using a semiclassical analysis of loop quantum black hole. We obtain a metric inside the event horizon that coincides with the Schwarzschild...
Recent Conceptual Consequences of Loop Quantum Gravity. Part III: A Postscript On Time.
Natural Philosophy Philosophy of Science Quantum Gravity
2008/4/22
With a view to the results discussed in the first two parts of this paper, the concept of time is revisited oncemore and chosen as an example in order to demonstrate the meaning of fundamental in both...
Recent Conceptual Consequences of Loop Quantum Gravity. Part II: Holistic Aspects.
Natural Philosophy Philosophy of Science Quantum Gravity
2008/4/22
Based on the foundational aspects which have been discussed as consequences of ongoing research on loop quantum gravity in the first part of this paper, the holistic aspects of the latter are discusse...
Recent Conceptual Consequences of Loop Quantum Gravity. Part I: Foundational Aspects.
Natural Philosophy Philosophy of Science Quantum Gravity
2008/4/22
Conceptual consequences of recent results in loop quantum gravity are collected and discussed here in view of their implications for a modern philosophy of science which is mainly understood as one th...
