Isaac Asimov, in his 1979 book A Choice of Catastrosphes: The Disasters That Threaten Our World, raised the possibility that mini-black holes created with the Big Bang may burrow into stars and cause them to wink out (pp. 92-96). Stephen Hawking in 1974 suggested that (to quote Asimov) "... in the first moments of the formation of the universe, innumerable black holes of all masses from that of a star down to tiny objects of a kilogram or less" were produced. The smaller ones Hawking dubbed "mini-black holes." I have two questions related to the above: 1) What is the current thinking about mini-black holes, including the creation of black holes of any size or mass with the Big Bang? 2) Has anyone seriously looked for missing stars? WRT (2), astronomers constantly search for any unusual variation or brightness (e.g., supernova) in any stellar object. Some researchers have also looked for brown dwarfs eclipsing background stars in the Milky Way or the nearby companion galaxies. However, has anyone actively compared past and current surveys of star fields for missing stars?
