    My favorite fact from that article (indeed xkcd) isn’t about neutrinos though, but this:

    Which of the following would be brighter, in terms of the amount of energy delivered to your retina:

    1. A supernova, seen from as far away as the Sun is from the Earth, or
    2. The detonation of a hydrogen bomb pressed against your eyeball?

    The answer is the supernova, by 9 orders of magnitude. So the supernova at the Sun’s distance is about a billion times brighter than a hydrogen bomb pressed against your eyeball.
