      This is one of those things regarding space where you think about the numbers involved and it makes your head hurt. Just the fact that a star will go supernova in my lifetime (well, it already has ) is mind boggling.
      It's never too early to start the Pre-game festivities

        In the context of space and numbers, it's mind boggling that anything would happen during your lifetime, it is so short.

        A tale told by an idiot, your nanosecond upon the stage.

          would (could) it not already have happened?
          how long does it take that light to get here?

            I think that is why Race parened "well, it already has," though he didn't say in prior lifetimes.

              mookie read that as perhaps another star. we don't see them all. that's why they call it space

                Yeah, the possibilities of what he meant are infinite.

                  Google says Betlegeuse is 642 Light years away. So if we are gonna see the "boom" in the near future, the actual event happened in the late 1300's.

                    FWIW I understood what you meant.

                    But it actually brings up a philosophical question about what time is. The idea that something is happening "now" but we won't see it for 700 years still assumes there is such a thing as a universal objective time ticking away in the background. But... there isn't. Time and space are tied together so it is equally valid to say that it hasn't happened "yet."

                    Time is one of those things like being and consciousness and causality and even extension in space that seems extremely simple until you start thinking about it and which then has no bottom. That's kept guys like Heraclitus and Parmenides and Zeno and Plato and Aristotle and a bunch of Muslims named al-Something and Leibniz and Berkeley and Kant and McTaggart and Bergson in business.

                      This is the exact reason why I like to keep focused on our own grain of sand (our solar system) and end it there

                          Imagine if you were 'right next to it' as it happened and survived long enough to notice it.

                            That would be unpleasant. Betelgeuse is large enough that if placed in our solar system at the position of the sun its surface would extend beyond the orbit of Jupiter. It's... big. (It's really light, though. Only about 20x the mass of the sun.)

                            To put it another way, Betelgeuse has an absolute magnitude of -5.14, a distance of 428 light years, and an apparent magnitude of +0.45.

                            Now, luminosity at distance A = (luminosity at distance B) × [(luminosity B)/(luminosity A)]^2.

                            If Betelgeuse was as close as the next nearest star, Proxima Centauri, 4.24 light years away, more than 100 times closer to us, then it would be more than 100^2 = 10,000 times the apparent magnitude. The stellar magnitude scales are reverse logarithmic. An object with a magnitude 5 higher than another's magnitude is 100 times dimmer. So Betelgeuse would have an apparent magnitude of approximately -10. All the time. The brightest star is Sirius, -1.5. Venus is -3. The full moon is -13. In other words Betelgeuse would be easily visible during bright daylight. On a moonless night with it high in the sky in a dark place, it would make you cast a shadow.

                            And that's before it explodes.
