The mere idea of geese spontaneously exploding mid-flight makes me giggle like a madman. 108.162.216.26 12:03, 29 October 2014 (UTC)

The explanation should point out that the comic is referring to the common misconception that there is a high chance that a visible star is already dead. The facts are explained but the context is missing. This misconception was also mentioned in a what-if, but I cant find it right now. The Milky Way is 120kly in diameter and most visible stars are much closer. With a lifetime of at least a couple millions of years the probability for a random star being dead is way below 1%. Given that there are 5000 stars visible to the naked eye (under best viewing conditions), this means that statistically there are maybe 5 stars in the entire night sky that are dead already. --108.162.231.215 09:10, 29 October 2014 (UTC)
- "With a lifetime of at least a couple millions of years" True only for the most massive stars. The average star in the Milky Way is around half a solar mass and will last around 50 billion years. So the probability of one of the 5000 stars visible to the naked eye having died in the last 1000 years is even smaller than "way below 1%". 199.27.128.146 16:45, 29 October 2014 (UTC)
- Although you are overstating things a bit, because more massive stars are more likely to be naked eye visible. According to Wikipedia today, no M-class stars are naked eye visible at all. 173.245.52.142 18:00, 29 October 2014 (UTC)
- Almost all stars have a lifetime of at least a couple milions of years. However, some stars have lifetimes that extend on for billions of years after those few million. Mulan15262 (talk) 23:08, 29 October 2014 (UTC) Mulan15262
I think this relates to a previous XKCD 1342: Ancient Stars (http://xkcd.com/1342/) where he makes the same joke of how stars may not necessarily be that far away. 173.245.54.206 17:22, 29 October 2014 (UTC)
No! The moving V of the geese is reminiscent of a light cone! I think that's what triggered Megan's absurdist fantasy. And indeed, we're seeing the geese as they were in the past. By about a microsecond. If enough readers agree I think this belongs in the explanation. ExternalMonolog (talk) 20:49, 29 October 2014 (UTC)
- The light cone thing is important I think. I read the whole discussion in the comic as a play on the concept of abosolute time vs relativity. And I found it hilarious with that interpretation. --108.162.249.220 21:38, 29 October 2014 (UTC)
