Causality Loopy

"Many years from now, a transgalactic civilization has discovered time travel. A deep-thinking temporal engineer wonders what would happen if a time machine were sent back to the singularity from which the big bang emerged. His calculations yield an interesting result: the singularity would be destabilized, producing an explosion resembling the big bang. Needless to say, a time machine was quickly sent on its way."

--Barry Dainton, Time and Space, 1958
