通古斯大爆炸
William H. DeSmedt is an American author of science fiction. His debut novel, "Singularity" (2004), explores the 1908 Tunguska event and the speculative hypothesis that it was caused by a submicroscopic, primordial black hole. Although "Singularity" is a work of science fiction, in the tradition of Michael Crichton, its premise is anchored in real-world science.
