<UmbralRaptor> APlayer: the null hypothesis got stabbed.
<APlayer> Normal distribution, yes. Standard deviation too
<awang> APlayer: Basically if that thing happened by chance the authors should go buy lottery tickets

<UmbralRaptor> SnoopJeDi, iximeow: As in do a flyby, but colliding not so much.
<APlayer> So it means certain to within 30 std. dev.

<iximeow> UmbralRaptor: that "what" was at the observation, not the tesla :P
<UmbralRaptor> ah
<iximeow> i'm consistently surprised at what we can measure :P
<SnoopJeDi> (recall the 68-95-99.7 rule for full width area under 1, 2, 3 σ)
<APlayer> Alright, got it
<SnoopJeDi> so 3σ is usually considered the cutoff at which you're very confident, except in HEP where 5σ is chosen fairly arbitrarily as the golden rule for discovery (after some large embarassments in the 70s)
<awang> I thought HEP was 6 sigma
<SnoopJeDi> err sorry 6 sigma

<SnoopJeDi> I think 5 sigma was the golden number for Higgs
<UmbralRaptor> Some fields go with 2 σ.
