Loop quantum cosmology Part--2
This subfield originated in 1999 by Martin Bojowald , and further developed in particular by Abhay Ashtekar and Jerzy Lewandowski , as well as Tomasz Pawłowski and Parampreet Singh , et al. In late 2012 LQC represents a very active field in physics , with about three hundred papers on the subject published in the literature. There has also recently been work by Carlo Rovelli , et al. on relating LQC to the spinfoam -based spinfoam cosmology . However, the results obtained in LQC are subject to the usual restriction that a truncated classical theory, then quantized, might not display the true behaviour of the full theory due to artificial suppression of degrees of freedom that might have large quantum fluctuations in the full theory. It has been argued that singularity avoidance in LQC are by mechanisms only available in these restrictive models and that singularity avoidance in the full theory can still be obtained ...
