That’s how the Earth got destroyed in “The Forge of God.” :)
Plot (spoils about 50% of the book)
A hostile alien probe discovers Earth, builds/grows three wildly different alien races, has them crash one each in the world’s three largest superpowers (one claiming to bring knowledge, one warning of an impending attack, one claiming to seek conquest), while robot ships plant explosives along the Mariana trench, but the primary attack is two singularities, circling earth in a decaying orbit, by the time anyone even begins to theorize about the cause of the anomalous gravity measurements across the world, both are already circling deep under Earth’s crust.
