Singularity Avoidance
> s.a. models in canonical quantum gravity; spacetime singularities.
* History: Early work on Gowdy
models using ADM variables was inconclusive; Work on FLRW models and black
holes by Bojowald et al using connection variables, and by Husain &
Winkler using metric variables, indicates that the singularity is avoided there;
Conclusions however seem to be dependent on the approach to quantization.
