1) After reading the source material one discovers that, this is an 'hypothesis.'
2) A contributing author, Adrienne Ertel, graduate student, University of Illinois, Champagne-Urbana, states that their hypothesized killer star supernova is actually outside the ' kill distance' from Earth, in which any damage would have ( could have ) occurred.
3) In order to 'prove' their hypothesis, they'd need radio-isotopic 244Pu, 146 Sm evidence from the appropriate-aged terrestrial stratum.
4) No search for the properly-aged stratum has been conducted.
5) No collection of the stratum has been accomplished.
6) No laboratory analysis of samples has been conducted.
5) No evidence exists, one way or another, to confirm or disprove the hypothesis.

Unless the reader made the effort to examine the 'evidence,' the headline might pass as 'fact.'
