Have early black holes left lingering traces?

Gribbin, John
June 1991
New Scientist;6/1/91, Vol. 130 Issue 1771, p20
Cites the results of research indicating that tiny black holes left over from the big bang may be responsible for the high energy cosmic rays that reach Earth from extragalactic space. Notion of primordial black holes dating back to the work of Stephen Hawking and his colleagues in 1970; Form of fundamental particles taken by the black holes.
