    Whenever I read about the latest thing Astronomers have seen, I have to do a little mental reminder that they are really looking back in time, and what we see is quite possibly no longer there.

    In Larry Niven’s Ringworld, there is a subplot that the center of the Milky Way has exploded and it’s a growing concern, but not terribly so, because the shock wave from the explosion that will wipe everything out will take 25,000 years to reach known space.Report

    • no longer there

      Whatever that means, relativistically speaking 🙂Report

      And now, for something completely different (but very similar)

      Dogs, and other animals with a highly developed olfactory sense, “see” (smell) the world differently than us. They can “see” backwards in time to what was there before, and not just what it’s there now, and can “see” al their surrounds at the same time.

      Every once in a while I think this could be great material to write a story truly from a dog’s POV, in which the dog relies more on smell and sound to explain his world and his actions

      (famous New Yorker cartoon: one dog to another, who looks a bit cross with the first: “It doesn’t matter he’s a jerk, of course I smelled his ass. It’s the polite thing to do”)

      And re Ringworld, the wave is actually an important thingReport
