Story summary

Primordial black holes pose a hidden danger to humanity, with those exceeding 10^17 grams unleashing lethal shock waves and smaller ones emitting deadly Hawking radiation. Fortunately, the odds of facing such a threat are slim, with only one potential fatality every two decades in our vast Milky Way galaxy.

History

Historical Context

Primordial black holes, theorized since the Big Bang, may pose risks through lethal shock waves and Hawking radiation. Historically, Stephen Hawking's 1974 theory suggested their existence in the Milky Way. While their detection remains challenging, advancements in astrophysics, such as the Fermi Gamma-ray Space Telescope, aim to observe their effects, echoing past efforts to understand cosmic phenomena and dark matter.
