Abstract
We review recent developments in the physical implications of two loop quantization strategies for the interior of a homogeneous dust cloud. The first is the loop quantization with holonomies and the triads while the second is with holonomies and the gauge covariant fluxes. Although both of the quantization schemes resolve the classical central singularity regardless of the initial conditions, they also lead to a distinct phenomenology. For the first loop quantization, we find that when the dust mass is larger than a threshold value, both black hole and white hole would form and their evolution is symmetric with respect to the bounce point, leading to black hole-white hole twins. In contrast, in the second quantization, the evolution of the outermost dust shell is asymmetric with respect to the bounce point, and as a result the black hole-white hole twins can never form. Even in the situation when both black hole and white hole can form, the mass of the latter is only 2/π of the mass of the former.
