A massive Population III star, or two merging black holes, might cause a hypernova—about 50 times more energetic than a “normal” supernova.

Brian Thomas, an astrophysicist at Washburn University in Kansas, and some of his associates have conjectured that a hypernova may have caused the Ordovician–Silurianmass extinction on Earth 440 million years ago.  However, there is no definitive evidence for this hypothesis.
