Abstract
Confident that black holes of stellar (\( {5-15}\,\, \mathrm{M}_{\bigodot} \)) and super (\( 10^{5}-10^{10}\,\, \mathrm{M}_{\bigodot} \)) mass do indeed exist, astrophysicists began naturally to wonder if black holes outside of these mass ranges also existed. Ones smaller than stellar mass (perhaps very small) may have formed in the early universe – primordial black holes. However, up until now there have been few serious attempts to search for them. The same is true of holes much larger than \(10^{10}\,\, \mathrm{M}_{\bigodot} \); if such objects did exist, they would have to be quite isolated from normal galactic matter to have escaped our detection.
