I was curious to how long it will be until the stars are not able to be seen due to light pollution. I started wondering this after reading Yummie's Flash comic Knite.

$\begingroup$ @TildalWave That is less an issue of light pollution as it is smog: fine particulate air pollution. A pretty shocking thought all the same. $\endgroup$– zibadawa timmyApr 13, 2015 at 0:42

$\begingroup$ @zibadawa timmy If skies were perfectly clear, as they are for example on the moon, we could have all the lights we wanted shining into the sky and it wouldn't affect limiting magnitude. Backscatter and haze are the problem; humidity, cloud, dust and pollution. $\endgroup$– Wayfaring StrangerApr 13, 2015 at 11:34

$\begingroup$ @TidalWave Then why is Hong Kong considered the most light polluted city in the world? $\endgroup$– zibadawa timmyApr 13, 2015 at 23:29

$\begingroup$ @TidalWave The first photo seems to indicate that you can still see stars in the Hong Kong night sky. Whereas earlier you were asserting that not just Beijing but almost the entirety of China was so light polluted that an entire generation has never seen a star or planet, and barely even the moon. So what is the definition that makes Hong Kong #1? $\endgroup$– zibadawa timmyApr 14, 2015 at 1:34
