So I was looking through some articles about primordial black holes the other day and it said that these black holes can be insanely tiny. Some of the articles state the mass could range from $10^{12}$ all the way to 1 solar mass.
But how could this be possible if when the matter is compressed to a black hole, the matter if less than the Chandrasekhar limit just becomes a white dwarf or if below Tolman-Oppenheimer-Volkoff becomes a neutron star.
Thank you in advance.
