Comment on 'Are the spectra of geometrical operators in Loop Quantum Gravity really discrete?' by B. Dittrich and T. Thiemann

Autor: Rovelli, Carlo

I argue that the prediction of physical discreteness at the Planck scale in loop gravity is a reasonable conclusion that derives from a sensible ensemble of hypotheses, in spite of some contrary arguments considered in an interesting recent paper by

Backreaction in Cosmology

Autor: S. Schander, T. Thiemann

Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 8 (2021)

In this review, we investigate the question of backreaction in different approaches to cosmological perturbation theory, and with a special focus on quantum theoretical aspects. By backreaction we refer here to the effects of matter field or cosmolog
