  1. Crazy to think that there’s so much energy being released that we can detect it 3 billion light-years away. And yet, if I understood correctly, these huge events happen weekly or even daily. The universe is a big place, man…

  2. Oh wow they actually used my colleagues video at 3:45. Really awesome!! I guess if anyone has any questions I can probably answer them.

  3. I wouldn’t be suprised if physicists are sitting on quite a few signals. Astronomy likes to go for five standard deviations for whatever reason when measuring confidence in a signal/event. To the rest of science fields this is borderline neurotic levels of surity, but it does mean we usually don’t get fake discoveries (also where planet 9 with its measly 3.9 standard deviations of confidence by the guy who discovered it gets its controversy from).

    To put this in perspective, 2 standard deviations is 95 confidence that the results are not random chance/error.

    You can still be wrong with that, it just gets progressively less and less likely its due to picking up a false positive. You could still interpret or associate data wrong though.
