LACK OF BLACK HOLE BURSTS. “The non-detection of such an event has a few explanations. First, the fraction of PBHs that make up the dark matter must be quite low for PBHs of the relevant mass scale. Thus it is plausible that not enough of these PBHs exist to subsequently evaporate and trigger gamma-ray detectors.” (PBHs = primordial black holes).
