This was fascinating to me because I never even considered the possibility that black holes could be inside stars, acting as initial seeds for star formation.
Turns out that primordial black holes (PBH) are a candidate for dark matter which has recently become more plausible with supporting evidence from LIGO/Virgo gravitational wave detections.
There is something quite elegant about black holes being responsible for dark matter, at least because that means we don’t need some unknown particle to explain it.
Yet it would be odd for black holes to transform immediately from exotic to mundane if it turns out they are everywhere all at once.
