    Multiple Supernovae

    Postulate that a Sufficiently Advanced Technology (ala OAUP) can detonate any star into an artificial supernova, for whatever reason (war, art project, religious worship...).
    Would we notice if there were half a hundred supernovae in one galaxy half a gigaparsec away in a few years? Would that stick out in the noise?

    Tom Mazanec is referring to the Orion's Arm Universe Project, a fictional scenario which includes an event where about thirty artificial supernovae are detonated within the period of a few months in a single cluster.

    If an advanced civilisation somewhere in the Sloan Great Wall performed a similar feat 1.6 billion years ago, the light from this event might start arriving next week. The light from these many supernovae would arrive at slightly different times (they would after all be a few light years away from each other, so they could not all explode simultaneously as seen from a distance). I think that some astronomer or other would notice all these separate events occurring a few weeks or months apart, but it would be interesting to see what the practical considerations would be.

    Ah, that makes sense now. I thought "ala OAUP" was an eccentric spelling of "Allez oup!" the old cry emitted by acrobats and magicians as they were performing a trick. ("Any sufficently advanced technology ..." and all that, you see.)

    But it's " la Orion's Arm Universe Project". D'oh.
