Loop quantum gravity might let black holes explode

An interesting article from Nature reports on the what might happen with early blackhole formations and might explain high energy cosmic ray sources.  In the article it describes “ tiny black holes that formed during the very early history of the Universe would now be ready to pop off like firecrackers and might be detected as high-energy cosmic rays or other radiation”

It goes further to explain that "The collapsing star would reach a stage at which its inside can shrink no further, because the loops cannot be compressed into anything smaller, and in fact they would exert an outward pressure that theorists call a quantum bounce”.

This is all based on the idea that timespace is quantum in nature and has a finite size, albeit very small. These are so called loops. Which sounds very much like a version of string theory.
