  Wikipedia (Near-Earth Supernova) says that a 25 ly away supernova would wipe out half the ozone layer so that’s probably the lower bound for what we want

  Pretty sure the curve should turn up on the right side at some point.

    Nah, happiness should asymptotically approach 0 happiness as distance increases, due to decreased brightness. Tho, I guess there could be a discontinuity at the crossover point of where we can no longer observe it and the happiness we can extract from understanding that there are those so far away we can never see them?

      At some distance, we can no longer see the stars or even the galaxy. A supernova will allow us to see in really distant past, maybe at the first generation with some really good lensing.

      Think ereandel but older
