Gravitationally collapsed objects of very low mass

It is suggested that there may be a large number of gravitationally collapsed objects of mass io- g upwards which were formed as a result of fluctuations in the early Universe. They could carry an electric charge of up to I 30 electron units. Such objects would produce distinctive tracks in bubble chambers and could form atoms with orbiting electrons or protons. A mass of 1017 g of such objects could have accumulated at the centre of a star like the Sun. If such a star later became a neutron star there would be a steady accretion of matter by a central collapsed object which could eventually swallow up the whole star in about ten million years.
