Higgs vacuum stability has important consequences for cosmology.
In particular, we argue that if the Higgs vacuum is metastable, then the dark
matter cannot contain a single black hole of mass less than 1015g
in our entire past light cone. In addition to being the destroyer microscopic black holes,
it may be possible that Higgs vacuum decay is a source of
primordial black holes during inflation.
