Where Has All the Xenon Gone?

LucidBeast writes "Xenon, the second heaviest of the noble gasses, is only found in trace amounts in the atmosphere. Atmosphere contains less xenon than other lighter noble gasses. Missing xenon has perplexed scientists and it has been speculated that it is hiding in the Earth's mantle. Now, a group at the University of Bayreuth in Germany thinks it might have found the answer. It turns out that xenon does not dissolve easily into magnesium silicate perovskite, and thus it cannot hide there. Because it had no place to hide, it is now gone forever."

    Because the a-hat tailgating you in a lifted truck with xenon headlights ruins your nightvision.

    Is this issue really the bulbs, or is it the asshole, the truck, or the tailgating ? My preference if someone is really close and trying to blind me is to turn my lights off, and let them light the road for me. Of course, this wouldnt be safe, so I keep coasting to a slower and safer speed. Eventually the asshole figures it out.
