Sholz's star passage and Human bottleneck both happened about 70,000 years ago. Millions of humans were reduced to only few thousands apparently due to the effects of Toba supervolcanic eruption. The paasage of Sholz's star also happened nearly at the same time and possibly it may related to the near extinction of humans.

Rouge stars zipping around the galaxy, make space more terrifying why not.

Maybe what they meant was that Neptune was the nearest planet to the red dwarf.

+Roger Kreil That is how I understood it.

Good job for putting the AU unjt into perspective.

Neptune is the nearest planet eh? That would make sense if perhaps you are broadcasting from Uranus...

1:20 Nearest planet? Whoever writes the script for this should leave this channel. Also, who ever checks these for errors before uploading should leave as well. This isn't a small mistake. I can't believe the person reading this read it and didn't say anything either.

+Njumkiy Lets Play : "How far is four point eight million miles? Well ... it's close to two thousand times as far as OUR NEAREST PLANET; NEPTUNE." It would take a considerable amount of will power to forge that quote into something forgivable.
