Smallest primordial black hole
WebbIt is believed that primordial black holes (PBHs) could have formed in the early universe from the collapse of large density fluctuations, and if so, could have observational implications - either from their gravitational effects, or the effects of their Hawking radiation (see [1, 2] for recent lists of the constraints).
