That was the prediction issued by Deep Thought, aka The God Machine, in response to the query regarding the burning question of when the planet Earth would meet its inevitable demise.
The answer was so pat and succinct, it was shocking in its directness. Still, it gave the denizens of Earth a little over seven hundred years to prepare by terraforming and colonizing Mars. Plenty of time, the Earthlings were assured.
The usual internecine squabbles broke out along the way. Some refused to believe in the infallibility of Deep Thought. Others wanted to stay behind and be destroyed along with the planet.
This led to the development of Boson-Higgs VI, the planet splitter, a bomb capable of cracking the Earth from mantle to core. It seemed like a good idea at the time.
As the final ships from Earth landed on Mars, one of the radical clerics in opposition to Deep Thought detonated the BH VI.
